indicted defendants-appellants Santo Ruiz and  Virgilio Ruiz,

two brothers,  for various crimes  arising out of  a December

1990  fire that  destroyed  their variety  store in  Roxbury,

Massachusetts.  After a  ten day trial, a jury  convicted the

defendants of maliciously destroying  by fire a building used

in interstate  commerce (18 U.S.C.   844(i)),  mail fraud (18

U.S.C.   1341), conspiracy  to commit the foregoing  offenses

(18 U.S.C.   371), and use of fire to commit a federal felony

(18 U.S.C.   844(h)(1)).  On appeal, the defendants challenge

the  district court's denial  of their motions  to acquit and

for new trial.  They also appeal their sentences.   We affirm

their convictions  but vacate their sentences  and remand for

resentencing.

evidence  in the light most favorable to the government.  See

plausible inferences, we "must choose the inference that best

standard  of review  in  mind, we  turn to  the facts  of the

case.1

A.  Facts
                     

          1.  Pre-Fire Events
                                         

           In February  1990, defendant  Santo Ruiz opened  a

retail business named Brothers Fashions and Multiple Services

("Brothers Fashions"), in the  basement area of a three-story

residential  duplex.    Three  of  Santo's  brothers,  Pablo,

Frederico,   and  co-defendant   Virgilio  Ruiz,   shared  an

apartment directly above the store.  The duplex comprised six

residential   apartments  occupied  by  a  total  of  sixteen

residents, including the building's owner.

                    
                                

1.  At the  end of the government's case,  Santo and Virgilio
Ruiz  moved for  judgment of  acquittal, pursuant to  Fed. R.
Crim. P.  29.  Because  the defendants presented  evidence in
their defense after  the denial of  the initial motion,  they
are deemed to have waived review of  the earlier motion.  See
                                                                         
United States v. de la Cruz-Paulino, 61 F.3d 986, 997-98 (1st
                                               
Cir. 1995); United States  v. Amparo, 961 F.2d 288,  291 (1st
                                                
Cir. 1992).   Thus, in reviewing  the defendants' sufficiency
of  the evidence challenge,  we consider,  in the  light most
favorable  to  the verdict,  the  evidence  presented in  the
defense  case.  See 2 Charles A. Wright, Federal Practice and
                                                                         
Procedure   463, at 643-45 (1982).
                     
          We note also that although  defendants' motions for
acquittal and new trial were filed more than seven days after
the  verdicts  were rendered  and  the  jury discharged,  the
motions were  timely because,  within that  seven-day period,
the district court extended the time allowable for making the
motions.   See Fed. R. Evid. 29(c) & 33; see also Carlisle v.
                                                                      
United States, 116 S. Ct. 1460, 1463-64 (1996) (holding that,
                         
absent  proper  time  extension,  a district  court  may  not
entertain an untimely Rule 29 motion).  Thus, we consider the
motions timely  and properly  preserved for our  full review.
See  id. at  1471  (explaining that  a sufficiency  challenge
                    
untimely  brought in  the trial  court  is subject  to "plain
error" review) (Ginsburg, J., concurring).

                             -4-
                                          4


          Santo  borrowed  $10,000   from  another   brother,

William  Ruiz,  as  the   start-up  capital  for  the  store;

additionally, Santo incurred  a debt of $4000  to William for

the store's  fixtures.2  The $14,000 debt  remained unpaid in

its entirety through the time of the fire.

          The  store sold  sundry items,  including clothing,

shoes,  blankets, cosmetics, household products, music albums

and  cassettes,  beverages and  candy.    Santo obtained  the

store's  merchandise  for  cash  from a  variety  of  sources

located in  Massachusetts, New Hampshire,  New York, Florida,

and California.

          Virgilio  Ruiz spent  much  time at  the store  and

frequently assisted  Santo, who  did not speak  English, with

needed  language  interpretation.   Although  Santo  was  the

putative owner of  Brothers Fashions,  the evidence  suggests

that  Santo  and  Virgilio  represented  to  others  a  joint

ownership  and responsibility  for the  store.   For example,

both Santo and  Virgilio signed  the lease for  the space  as

well  as  the business  certificate  filed with  the  City of

Boston.

          In  early   September  1990,  Santo   and  Virgilio

negotiated for the installation of a store security alarm and

jointly  signed  the  agreement  with  the  alarm  monitoring

                    
                                

2.  William had operated a convenience market in the basement
space before the opening of Brothers Fashions. 

                             -5-
                                          5


service.   The alarm, which could detect heat and motion, was

designed  primarily to  trigger  when a  burglar entered  the

premises after hours; a sufficient  amount of smoke from fire

could also trigger a response.  The alarm, however, would not

operate  unless   the  subscriber  activated  the  system  by

entering  the proper pass code.   About two  weeks before the

fire, Santo ceased activating the alarm system.

          In  early November 1990,  approximately nine months

after Brothers Fashions opened and about six weeks before the

fire,  Santo   and  Virgilio  obtained   $40,000's  worth  of

insurance  coverage  for   the  store's  contents.     During

discussions   with  the   insurance  agent,   the  defendants

specifically asked  about the processing and  payment of loss

claims.   Although such information  was not a  usual part of

the agent's initial discussions about  insurance coverage, in

response  to this  inquiry,  he explained  that receipts  and

cancelled  checks   would  be  required  to   prove  a  loss.

Virgilio, representing Brothers Fashions, signed an insurance

finance agreement.   Coverage  began shortly thereafter  when

the brothers  tendered a down payment  of approximately $750.

The  payment schedule  provided that  a first  installment of

approximately $250 would fall due on December 20, 1990.

          Santo kept in  his possession most of  the time the

only  set of keys to  Brothers Fashions.   Before closing the

business each  day, Santo  would secure the  store-front with

                             -6-
                                          6


three heavy  metal security shutters, each  fastened with two

padlocks.   The store's  back door, which  was rarely opened,

measured  three-feet  wide by  four-feet  tall  and could  be

opened only from the inside of the store.  It  was secured on

the inside with a sliding lock and at least one wooden cross-

bar laid across the  door.  An outer iron grate,  locked from

the inside with a padlock, further secured the back door.

          Less  than  two  days  before  the  fire,  Brothers

Fashions was  fully  stocked with  merchandise  displayed  on

clothing racks, shelves, and in display cases.

          2.  The Fire
                                  

          Around 2:00  a.m. on  Sunday, December 16,  1990, a

fire raged through Brothers Fashions.  The close proximity of

the  store  to a  fire  station  resulted in  near  immediate

response.    Nonetheless, the  blaze  was  serious enough  to

warrant   the  services  of   some  seventy  fire  department

personnel and over one dozen fire vehicles.

          Arriving  at  the scene,  fire-fighters encountered

the metal security shutters  lying in the street in  front of

the store;  the shutters  apparently had been  blown off  the

store-front by a  powerful explosion.  A  fire-fighter in the

first group to  reach the  back of the  building noticed  the

store's back door standing open with flames shooting out from

the  basement.    The  fire-fighters  extinguished  the  fire

without forcible entry of the property.

                             -7-
                                          7


          Normally, when a store stocked with clothing burns,

piles  of clothing in various  stages of ruin  remain.  After

the  fire at  Brothers  Fashions was  suppressed, however,  a

casual inspection  of the damaged store  revealed very little

burned or  charred merchandise; rather, all  that was visible

were a  few beverage bottles,  some canned goods  and minimal

charred foodstuffs.   The  dearth of charred  merchandise and

the complete absence of clothing remnants in the store evince

that it was nearly empty when it burned.

          All  of the  apartment  tenants,  except  Virgilio,

escaped  unharmed from  the burning  building.   None  of the

tenants, including Virgilio, required fire-fighter assistance

to evacuate.  Virgilio suffered second and third degree burns

on his  ankles, a severe  cut above  his left eye,  and large

bruises  below his  left  eye  and  across  his  chest.    An

ambulance  carried him from the  scene to the hospital, where

he remained for eighteen days.

          3.  Post-Fire Events
                                          

          Subsequent  investigation  revealed  that the  fire

originated  in two  distinct locations  within the  store and

burned in an unusual manner.   Specifically, the burn pattern

indicated  that an  accelerant,  such as  gasoline, had  been

poured  over  a counter  and  other  areas.   The  building's

electrical  and natural  gas  distribution systems  showed no

sign  of having caused or contributed to the fire.  Following

                             -8-
                                          8


the fire, Boston  Gas Company, the  natural gas provider  for

the building,  conducted  a search  of  its records  for  the

period from 1984 through the time of the fire for any reports

of gas leak  repairs at  the building.   The search  revealed

nothing.

          Sometime within the first two weeks after the fire,

John  Greenaway, who had been hired for carpentry work on the

premises, opened up the boarded-up store so  that Santo could

retrieve an empty clothes  rack.  In January 1991,  Santo and

Virgilio prepared,  jointly signed  and submitted a  claim to

their insurer --  via certified mail -- asserting  a contents

loss  of some $48,000.   The claim detailed  various items of

store   merchandise  and  fixtures,  including  thousands  of

dollars'  worth  of  men's and  women's  clothing,  curtains,

shoes, blankets, music albums and cassettes, videos, watches,

candy, household items and toys.

          Contrary  to the  insurance agent's  earlier advice

and the  insurance company's request, the  defendants did not

submit any  receipts, invoices,  or other records  to support

their  claim of loss.   Instead, the  defendants claimed that

the fire destroyed all such records and submitted a couple of

photographs purporting to represent the  store merchandise at

the  time of the fire  and a cancelled  check from Virgilio's

bank account  for approximately $15  in cigarette tax.   When

                             -9-
                                          9


asked by the  insurance company, Santo  could not recall  the

names of any of his retail merchandise suppliers.

          At various times before trial, Virgilio related his

version of the  fire events  to  his  attending physician,  a

Boston  Fire  Department  investigator,   and,  in  a   sworn

deposition,  representatives of  the insurance  company.   He

professed  a general  inability  to recall  clearly and  gave

somewhat  inconsistent accounts of  the fire events.   To the

extent  Virgilio's  various  stories overlap,  they  indicate

that: he awoke in  the first floor apartment to  the smell of

smoke, went  to the living room  to check the gas  heater and

saw  smoke  coming  through  the  floor;  he  then  heard  an

explosion and ran to awaken his sleeping brothers (Pablo  and

Frederico)  to  warn  them of  the  fire;  he  picked up  the

telephone to call the fire department, but the line was dead;

he proceeded to run out the  front hallway of the duplex  and

down  the stairs toward the building's front exit; on his way

out to the sidewalk in front of the duplex, another explosion

occurred and his  "fuzzy" socks caught  on fire, causing  the

injuries to  his ankles; at some point, he ran into a door --

perhaps the front door  of the apartment unit --  causing his

bruises and the severe cut above his eye.

          4.  The Defendants' Case
                                              

          The defendants  presented a joint  defense, calling

to the stand  members of the  Ruiz family: Pablo,  Frederico,

                             -10-
                                          10


Santo,  and  Rosa  (Santo's   wife).    Pablo  and  Frederico

testified  that, on the night  of the fire,  Virgilio went to

bed around midnight, and they  retired soon thereafter.  They

stated  that Virgilio later woke them up because of the fire.

Frederico  testified  that  he   then  dressed  quickly   and

proceeded  out the  front door.   As  he descended  the front

stairs,  he met Virgilio, who  was bleeding from his forehead

and down his face.   Frederico and Virgilio ran out the front

of  the building together.   Frederico was not  injured -- by

flame  or otherwise  --  as he  exited.   Upon  reaching  the

sidewalk in front of the building, he noticed fire coming out

of the basement store.  Frederico said that he  then told the

fire-fighters that Pablo was still inside the building.

          Pablo testified that his only avenue of escape from

the  burning building  was  the apartment's  back  door.   He

stated  that when  he exited  the building,  he  observed two

fire-fighters, who, he says, had been attempting  to pry open

the  apartment's back door  to let him  out.  Both  Pablo and

Frederico testified  that they  saw fire-fighters force  open

the  store's back door, which, they claimed, had been closed.

They  further claimed that, upon the opening of the back door

-- which measured  four-feet by  three-feet --  fire-fighters

emerged from  within  the store  wearing  full  fire-fighting

regalia, including oxygen tanks and masks.

                             -11-
                                          11


          Santo testified in his  defense.  He explained that

he  initially did  not insure  the  contents of  the Brothers

Fashions  because he  wanted first  to see  how the  business

fared.   He testified that only he  knew the alarm pass code,

and  that he failed to  activate the alarm  for several weeks

before the  fire because of  the recurrence of  false alarms.

He had deduced that  rats entering the store after  hours (to

eat candy) triggered the  alarm, and he wanted to  "kill" the

rodents before further engaging the alarm.  He testified that

he  complained  about  the rats  to  both  the  owner and  to

Greenaway,  who,  in turn,  testified  that  Santo had  never

complained to him about a rat problem.

          Santo suggested  that a  natural gas  explosion may

have contributed to the fire.   Specifically, he claimed that

about one month before the fire, he called Boston Gas because

he smelled  a  natural  gas leak;  contrary  to  other  trial

testimony, he claimed that Boston Gas personnel then came out

to the store  and fixed  the leak.   Santo further  testified

that  there  may have  been paint  and  paint thinner  in the

store, as well as household detergents, that might have acted

as  an  accelerant for  the fire  and  would account  for the

peculiar burn patterns.

          Santo testified that on  December 15, 1990, the day

before the fire, the store was fully stocked.  That night, he

explained, he had closed the store between 5:00 p.m. and 6:00

                             -12-
                                          12


p.m. and secured  the front  entrance.  He  insisted that  he

left the  back door fully secured and that he retained in his

possession the only  set of store keys.  He  then went to his

home in Dorchester.   The next morning, around 6:00  a.m., he

received a call at home informing him of the fire.  He walked

to  the store (his car was  not operational), arriving around

8:00 a.m..

          Santo further testified  that, upon his arrival  at

the  fire scene, he  saw ten to fifteen  people in and around

the  burned  store, including  people  from  Boston Gas,  and

Greenaway's  son.   He said  the  people were  removing half-

burned items  from the store.   He admitted at  trial that he

had never previously mentioned his observance of the looters,

even to the insurance company.  He also testified that he did

not attempt to stop the looting because the merchandise taken

was, in any event, ruined.

          Santo admitted  that, although he did  not speak or

understand  English   and  had   to  rely  on   Virgilio  for

translation, he  fully understood his actions  when he signed

the lease to  the store, the business certificate,  the alarm

system contract, and the insurance  claim for $48,000 in lost

inventory.    Santo  denied  removing, or  asking  anyone  to

remove, the  merchandise  from Brothers  Fashions before  the

fire.  He also denied  lighting the fire or asking  anyone to

light the fire.

          The defendants painted  a picture  of a  prosperous

store that earned some $600 to $1000 in retail sales per day,

suggesting  the  absence of  a  motive  to collect  insurance

proceeds.   The  defendants also  attempted to  establish the

bias of various trial witnesses.   For example, they produced

(contradicted)  evidence of  the  unlawful  absence of  smoke

detectors in the  duplex, suggesting that  the owner had  her

own  motive to  collect insurance  proceeds.   The defendants

also  suggested  that  the  carpenter  Greenaway  was  biased

because  he had married the  owner's niece in  1990 and, upon

the owner's  death, the  owner's niece stood  to inherit  the

building.

          1.  Relevant Law
                                      

          To  prove a  violation of  18 U.S.C.    844(i), the

government   must  establish  that   the  defendants:     (1)

maliciously damaged  or destroyed, or attempted  to damage or

destroy,  (2)  by fire  or an  explosive,  (3) a  building or

personal  property  used in  interstate  commerce  or in  any

activity  affecting  interstate  commerce.    The  government

sought  to prove that Virgilio set the fire, and Santo either

aided  and  abetted him,  or  reasonably  could foresee  that

Virgilio would  set the  fire in  furtherance of  an unlawful

conspiracy.

                             -14-
                                          14


          To prove aiding and abetting on  the part of Santo,

the  government  had to  prove  that  Virgilio committed  the

arson,   and  that   Santo   associated  himself   with,  and

participated in,  the arson "as something he  wished to bring

about, and sought by his actions to make it succeed."  United
                                                                         

States  v.  Loder,  23  F.3d  586,  590-91  (1st  Cir.  1994)
                             

(internal quotation  marks and citations omitted);  see Nye &
                                                                         

Nissen  v.   United  States,   336  U.S.  613,   619  (1949).
                                       

Alternatively, to  convict  Santo of  the  substantive  arson

offense,  the government  had  to establish  that  Virgilio's

setting of the fire was a foreseeable act done in furtherance

of  their  unlawful  conspiracy.   See  Pinkerton  v.  United
                                                                         

States, 328 U.S. 640, 647 (1946).
                  

          To prove  the underlying conspiracy --  a predicate

to Santo's Pinkerton liability as well as a substantive count
                                

in  the indictment -- the  government needed to establish the

defendants'  knowledge  and  voluntary  participation  in the

agreement, and an overt act in furtherance of it.  See United
                                                                         

States v. Sawyer,  85 F.3d  713, 742 (1st  Cir. 1996).   "The
                            

agreement  need  not  be  explicit; a  tacit  agreement  will

suffice."   Id.   To  establish voluntary  participation, the
                           

government must prove both the intent to agree and the intent

to effectuate  the object of  the conspiracy.   See  id.   Of
                                                                    

course,  direct evidence is not required  to prove either the

agreement (which  may be inferred from  circumstances) or the

                             -15-
                                          15


defendants' participation in it.   See id.; United  States v.

          2.  Application
                                     

          The  evidence more than adequately established that

someone deliberately torched Brothers  Fashions with the  aid
                   

of an accelerant.  Further, there is little question that the

store was  used in an activity  affecting interstate commerce

both  because  it  was  a rental  property,  and  because the

merchandise   purchased  for   resale  moved   in  interstate

commerce.   See United States v. DiSanto, 86 F.3d 1238, 1247-
                                                    

48 (1st Cir. 1996)  (holding that "rental property is  per se
                                                                         

sufficiently connected  to interstate commerce"  for purposes

of    844(i)) (explaining  further  that  the  jurisdictional

element is  met where restaurant received  food supplies that

travelled in interstate commerce); see also Russell v. United
                                                                         

States, 471 U.S. 858, 862 (1985).
                  

          The more  troubling question is whether  or not the

evidence sufficiently proved that Santo and Virgilio were the

parties criminally responsible  for the fire.   We note  that

the case  against the  defendants is  largely circumstantial.

Circumstantial evidence does not represent the proposition in

question, but asserts "'something  else, from which the trier

of  fact may  either (i)  reasonably infer  the truth  of the

proposition,  .  . .  or (ii)  at  least reasonably  infer an

increase  in the probability that  the proposition is in fact

                             -16-
                                          16


true.'"  U.S. v. Clotida, 892 F.2d 1098, 1104 (1st Cir. 1989)
                                    

(quoting  1 D. Louisell  & C. Mueller,  Federal Evidence   94
                                                                    

(1977)).    Although   circumstantial  evidence  requires  an

inferential   step  in   its  proof,   there  is   "no  legal

distinction"  between circumstantial  and direct  evidence in

the context of a Rule 29 motion.  Id.; see Olbres, 61 F.3d at
                                                             

971.    We recognize  that  "the government's  proof  may lay

entirely  in  circumstantial  evidence,"  United   States  v.
                                                                     

Valerio,  48 F.3d 58, 63-64 (1st Cir. 1995); we are, however,
                   

"loath to stack inference  upon inference in order  to uphold

the jury's verdict."  Id.
                                     

          The government produced  direct evidence that Santo

had in his possession the only keys to the store on the night

of the fire, that  the store's back door, rarely  opened, was

open at the time of the fire, and that Brothers  Fashions had

been emptied of  almost all  merchandise at that  time.   The

jury thus could rationally infer that, because only Santo had

the means to  access the  store that evening,  he opened  the

back  door from the inside  of the store  sometime before the

fire.   Santo's exclusive access also  permits the conclusion

that  he  was  involved  with  the  removal  of  the  store's

merchandise before the fire.   The jury could infer  that his

new   and  uncorroborated  testimony   about  looters  was  a

fabrication  to  account  for   the  lost  merchandise  --  a

                             -17-
                                          17


fabrication  intended  to  cover  up  his  knowledge  of  and

involvement in its removal.

          The  jury could  conclude that  Santo lied  when he

testified  that he discontinued activating the security alarm

shortly  before the fire because of rats.  From this untruth,

the  jury could  infer  that Santo's  unexpressed reason  for

failing to engage  the alarm  was to nullify  its ability  to

detect both the  removal of  merchandise and the  fire.   The

jury could further find  that Santo lied when he  stated that

he left  the store's back  door secured on  the night of  the

fire and that, in fact,  he left it open for Virgilio  to set

the fire.

          A  jury  could   rationally  infer  that   Virgilio

personally set fire to Brothers Fashions.  Virgilio, the only

apartment tenant injured by the fire, had severe burns on his

ankles, consistent  with  direct and  prolonged  exposure  to

flame;  yet Frederico, who  exited the  building in  the same

manner and  through the  same area  as  claimed by  Virgilio,

testified  that he was not injured in  any manner and that he

did not encounter any  fire until he reached the  sidewalk in

front of  the building,  where he  viewed the  fire emanating

from the  store.  The  jury could  also choose not  to credit

Virgilio's unembellished and confused account of the cause of

the injuries to his face and body and infer that, in fact, he

                             -18-
                                          18


suffered those  injuries escaping the store  (perhaps out the

small back door) after lighting the fire.

          The jury  could further  find that Santo  lied when

testifying that: (1) he had nothing to do with the removal of

the store's  contents, (2) he  observed looters at  the store

the morning after the fire, and (3) Boston Gas repaired a gas

leak at the store one month before the fire.   The jury could

also conclude  that  Virgilio lied  about the  source of  his

injuries.   Lies such as these legitimately support a finding

of guilt.  See  United States v. Hadfield, 918  F.2d 987, 999
                                                     

(1st Cir. 1990)  (finding inference of guilt could  have been

bolstered  by defendant's  "tall  tale");  United  States  v.
                                                                     

Jimenez-Perez,  869 F.2d  9, 11  (1st Cir.  1989) (explaining
                         

that  the  jury's  disbelief   of  defendants'  story  allows

legitimate inference  "that the fabrication was  all the more

proof of their guilt").

          As  to  motive,  although  the  government  did not

produce   evidence  that  Brothers  Fashions  was  a  failing

business,3  the defendants  clearly  stood to  gain from  the

insurance  proceeds.  Moreover, the jury could have given due

weight to the fact that the defendants did not have insurance

for the first nine months of the store's operation,  obtained

it  only six weeks before  the fire, and  expressed  peculiar

concern about claim payments  and proof of loss requirements.

                                          19


Further, the fire occurred just four days before the due date

of  the first installment payment, but after the down payment

had already triggered coverage.

          In sum, although not overwhelming, the evidence was

sufficient to prove beyond a  reasonable doubt that (1) Santo

and Virgilio  conspired to  set afire Brothers  Fashions, (2)

Virgilio set the  fire, (3) Santo  assisted Virgilio in  this

task  by  providing access  to the  store  and by  failing to

engage the alarm, and (4) Santo reasonably could foresee that

Virgilio would set the fire in furtherance of the conspiracy.

Although  the evidence does not compel a finding of guilt, it
                                                  

need not "exclude every reasonable hypothesis of innocence or

be wholly  inconsistent with every conclusion  except guilt."

United  States v. Laboy, 909  F.2d 581, 588  (1st Cir. 1990).
                                   

The jury  was "free to choose  among reasonable constructions

of evidence,"  id.,  and  the trial  evidence,  as  a  whole,
                              

permits a conclusion of guilt beyond a reasonable doubt.  See
                                                                         

id.  We  cannot say that the jury's verdict  on the arson and
               

conspiracy counts was irrational.

C.  Mail Fraud
                          

          Little discussion  of this count is  necessary.  To

prove  mail fraud,  the government  must establish:  "(1) the

defendant's knowing and willing  participation in a scheme or

artifice to defraud with the specific intent to  defraud, and

(2) the use of the mails . . . in furtherance of the scheme."

                             -20-

Sawyer,  85  F.3d  at 723.    There  was  more than  adequate
                  

evidence  to  prove  that  Santo  and Virgilio  intentionally

agreed  to  collect   insurance  proceeds  fraudulently,  and

together  submitted, by  mail,  a false  insurance claim  for

merchandise they knew had not been lost in the fire.  We will

not disturb the jury's verdict on this count.

          The defendants alternatively challenge the district

court's denial of their new trial  motions, claiming that, on

the weight  of the evidence, their  convictions constituted a

miscarriage  of justice.  A district court's power to order a

new  trial is  greater than its  power to grant  a motion for

acquittal.   See United States v. Rothrock, 806 F.2d 318, 318
                                                      

(1st  Cir. 1986).   In  considering a  new trial  motion, the

court  may consider both the  weight of the  evidence and the

credibility of witnesses.  See id. at 321.  Where a new trial
                                              

motion  is based upon the  weight of the  evidence, the court

may not order a new trial "unless it is quite  clear that the

jury has reached a  seriously erroneous result."  See  id. at
                                                                      

322  (internal quotation  marks and  citations omitted).   We

review  the district court's ruling on a new trial motion for

abuse of discretion.  See id. 
                                         

          True,  the trial  evidence  was in  conflict.   The

jury, however, was not compelled to credit Virgilio's account

                             -21-
                                          21


of  the  manner  in  which  he  was  injured,  or  Pablo  and

Frederico's testimony that fire-fighters forcibly entered the

store's  back  door.    The   jury  could  have  agreed  with

Virgilio's   argument  that,   given  the   evident  powerful

explosion in  the store,  his injuries  would have  been more

severe, or worse, he would not have  survived had he been the

arsonist.  The jury was warranted, however, in rejecting this

theory.

          The   strongest   competing  theory   of  innocence

concerns Santo's involvement in  the arson.  Put  simply, the

jury could have  reasonably found that Santo knew  nothing of

the fire  before its  occurrence, but  acted as  an accessory

after  the fact both to  protect Virgilio and  to profit from

fraudulently obtained insurance proceeds.   Santo insisted in

his  testimony, however, that he had the only means of access

to the store on  the night of the  fire and that he left  the

back door secured that evening.  In  contrast, the government

produced direct, credible evidence that the back door was not
                                                                         

closed at the  time of  the fire; while  the jury might  have

found  that Virgilio opened  the door, or,  perhaps, that the

explosion blew the  door open (although no  witness opined as

such),  given  Santo's  staunch  refusal  to  allow  for  the

possibility  that someone  else may  have had  access to  the

store,  the jury  could  and did  plausibly  find that  Santo

opened the door.   The evidence that Santo obtained insurance

                             -22-
                                          22


coverage  and disengaged  the alarm  shortly before  the fire

constitutes  further proof  of  his prior  knowledge of,  and

involvement in, the arson-for-profit scheme.  Finally,  other

than  generally  to  deny  any involvement  with  the  arson,

Santo's  trial testimony  did nothing  to support  the theory

that he was an unwitting dupe in Virgilio's criminal plan.

          The largely  circumstantial nature of the  proof in

this case  gave rise to competing  plausible inferences, some

pointing  to  guilt and  others to  innocence.   The  jury is

charged with choosing between such inferences, see Olbres, 61
                                                                     

F.3d at  972,  and, having  had  the opportunity  to  observe

Santo's trial testimony  and demeanor, it saw  fit to convict

him  on all counts.  While reasonable people could have found

otherwise, "a trial judge  is not a thirteenth juror  who may

set  aside a verdict merely  because he would  have reached a

different  result."  Rothrock, 806  F.2d at 322.   Because we
                                         

cannot say the jury reached a seriously  erroneous result, we

find  no  abuse  of   discretion  in  the  court's  carefully

considered refusal to grant Santo or Virgilio a new trial.

Moreover,  not only  did he  fail timely  to raise  the issue

          Virgilio contends  that  the prosecutor  asked  two

questions  of  Pablo Ruiz  that  were  calculated to  inflame

ethnic  prejudice in  the jury.   Some  context is  in order.

Pablo  testified that,  although  he received  many years  of

education in  the Dominican  Republic and earned  an advanced

degree in agriculture, he  could not find work in  the United

States because he did not speak English.  When later asked by

the prosecutor how  he could  remember at trial  the time  he

went to bed on  the night of the fire  (some three-and-a-half

years earlier) Pablo replied, "Well, if I can remember what I

studied  during 23 years, I should be able to remember a part

of what happened that night."

                    
                                

4.  Virgilio  also suggests  that three  of the  jury members
were  biased  because they  had  relatives  in the  insurance
industry.  Because Virgilio failed to raise the  issue below,
and fails adequately to  develop it on appeal, we  decline to
address it.

                             -24-
                                          24


          After  further questioning  about the  fire events,

during which Pablo's credibility  was called into question by

various inconsistencies, the prosecutor rekindled the subject

of Pablo's inability to find agricultural work in the  United

States.  The following exchange ensued:

          [The Prosecutor]:  What about California,
          .  . .  you ever  tried to  get a  job in
          agriculture in California?

          [Court   overrules   the  objection   and
          directs the witness to answer yes or no]

          [Pablo Ruiz]:  No.

          [The Prosecutor]:   What about Texas, did
          you ever --

          [Court sustains objection].5

          In  its post-trial  order  denying  the  defendants

motions for acquittal and new trial, the district court found

that "the  now disputed  cross-examination of Pablo  Ruiz was

proper,  did not constitute a racist appeal to the jury, and,

when viewed in context,  was not material in any event."   We

agree.   We  have  warned  that  "courts  must  not  tolerate

prosecutors' efforts  gratuitously to inject issues like race

and  ethnicity  into  criminal  trials."   United  States  v.
                                                                     

Saccoccia, 58  F.3d 754, 774  (1st Cir. 1995),  cert. denied,
                                                                        

116 S. Ct. 1322 (1996).  To the extent the disputed questions

here  unnecessarily  (albeit  marginally)  invited  ethnic or

cultural prejudice, we strongly disapprove.  While,  however,

                    
                                

5.  Defense counsel did not press for any further redress.

                             -25-
                                          25


the  inquiries  may have  been  of  borderline relevance  and

materiality,   it  was  Pablo   who  initially   offered  the

explanation that his inability to speak English precluded his

employment in  the field  for  which he  was most  qualified.

Under  the circumstances of this case, we cannot say that the

prosecutor impermissibly  injected into  the trial  a harmful

appeal  to any ethnic  bias in the  jury by asking  these two

questions.  See id.6
                               

          Virgilio also claims that the prosecutor frequently

"bellowed offensively at defense testimony" and "screamed  at

the jury with totally inappropriate accompanying facial moues

and  flailing gesticulation."    Virgilio did  not raise  any

objection to the prosecutor's  style or manner at trial.   In

its post-trial  order, the district court  found that, "while

the prosecutor's closing argument was loudly and passionately

delivered,  it  did  not  exceed the  bounds  of  propriety."

Having failed on appeal to  develop his argument or  explain,

with any detail, how  the prosecutor's conduct prejudiced the

trial, Virgilio cannot prevail on this challenge.7

                    
                                

6.  We also note that the district court carefully instructed
the jury, at some  length, that it must not draw  any adverse
inference from  the fact  that the  defendants were  from the
Dominican Republic and were not native English speakers.

7.  To the  extent Virgilio suggests on appeal that his trial
counsel rendered ineffective  representation, that  challenge
is  not  properly  before us.    United  States v.  Martinez-

          The defendants also challenge their convictions and

sentences under  18 U.S.C.    844(h)(1),  which provides,  in

relevant part: "Whoever  . . . uses  fire or an  explosive to

commit any [federal] felony  . . . shall, in addition  to the

punishment  provided   for  such  felony,  be   sentenced  to

imprisonment for 5 years but  not more than 15 years. .  . ."

The indictment  charged Santo and Virgilio with using fire to

commit  mail fraud,  a violation  of 18  U.S.C.   1341.   The

defendants  claim,  however, that  "fire"  was  not used  "to

commit" mail fraud, but rather, the "mailing of articles" was

used to commit mail fraud.   They contend that fire  may have

been used  to commit the arson,  "but it was not  the letter,
                                          

envelope  or stamp,  or  handwriting/printing/typing used  to

commit  mail fraud."  In the past, we have implicitly assumed

the  legal conclusion  that defendants  now challenge.   See,
                                                                        

e.g.,  United States v. Lombardi,  5 F.3d 568,  569 (1st Cir.
                                            

1993)  (involving   844(h)(1)  conviction for  using  fire to

                    
                                

denied,  116  S. Ct.  1343 (1996).    Further, to  the extent
                  
Virgilio submits new  evidence in support of  his request for
new  trial, that evidence must be brought to the attention of
the  district court in the first instance, either in a timely
motion  pursuant to  Fed. R.  Crim. P.  33, or  on a  writ of
habeas corpus pursuant to 28 U.S.C.   2255.

commit mail fraud where defendant arranged arson fraudulently

to secure insurance proceeds).8

          Defendants'  challenge  calls  into   question  the

meaning of the  phrase "uses fire  . . .  to commit  [certain

crimes]."   We have not  previously been presented  with this

issue.   We begin our  analysis with the  statute's language.

See  Bailey v.  United States,  116 S.  Ct. 501,  506 (1995).
                                         

Because  the  word  "use"  is  not  defined  by  statute,  we

"construe it in accord with its ordinary or natural meaning."

Smith v. United States, 508 U.S. 223, 228 (1993); see Bailey,
                                                                        

116 S. Ct. at 506.   The word is "variously defined  as '[t]o

convert  to one's  service,' 'to  employ,' 'to  avail oneself

of,'  and 'to  carry out a  purpose or action  by means of.'"

Bailey, 116 S. Ct. at 506  (quoting Smith, 508 U.S. at 228-29

International Dictionary  of  English Language  2806 (2d  ed.

1949) and Black's Law Dictionary 1541 (6th ed. 1990))).

          We think  it plain that the  defendants "used" fire

to commit mail fraud within the meaning of   844(h)(1).9  The

                    
                                

8.  We also note that the government has frequently charged a
  844(h)(1)   offense  in   connection   with   mail   fraud,
specifically  where a  defendant  sought to  secure insurance
proceeds for  property  he had  burned.   See,  e.g.,  United
                                                                         
States v. Lombardi, 5  F.3d 568, 569 (1st Cir.  1993); United
                                                                         
States  v. Bennett, 984 F.2d 597, 604 (4th Cir. 1993); United
                                                                         
States v. Schriver, 838 F.2d 980, 981 (8th Cir. 1988).
                              

9.  Defendants also challenge the sufficiency of the evidence
underlying  this  count.   For  the  reasons discussed  above
concerning the  arson, conspiracy  and mail fraud  counts, we

                             -28-
                                          28


defendants set fire to Brothers Fashions "to carry out" their

scheme to  deceive the insurance company  into making payment

for claimed losses.   Specifically, the fire constituted "the

means"  by  which  the  defendants attempted  to  create  the

appearance  of a legitimate loss of insured items.  While the

defendants also "used" the mails in furtherance of the scheme

to   defraud,  that   does  not   diminish  the   fact  that,

additionally, they "employed" or "availed themselves of" fire

to  effect  their  scheme.    Cf.  Smith,  508  U.S.  at  230
                                                    

(explaining that including one  method of "us[ing] a firearm"

does  not   result  in  excluding  others).     Finally,  the

defendants make no argument that the placement and purpose of

the  word  "use"  in  its  statutory  context  undermine  the

applicability of   844(h)(1) here.  See Bailey, 116 S. Ct. at
                                                          

506-07  (considering  disputed  language  in the  context  of

                    
                                

find  the evidence sufficient to  permit a jury  to find that
Santo and Virgilio used fire to commit mail fraud.

overall  statutory scheme).  No basis for such an argument is

apparent.10

          In  conclusion, we  see  no basis  to overturn  the

defendants'  convictions and  attendant  penalties  under  18

U.S.C.   844(h)(1).

          Defendants  appeal the  court's application  of the

federal arson  guideline.   See  U.S.  Sentencing  Guidelines
                                           

Manual  [hereinafter "U.S.S.G."]    2K1.4(a)(1)-(4) (1994).11

In  the sentencing context, we review factual determinations,

which must be  supported by a preponderance  of the evidence,

for clear error.  See United States v. McCarthy, 77 F.3d 522,

cert.  denied, 65 U.S.L.W. 3505 (U.S. Jan. 21, 1997) (No. 96-
                         

5017).    We  review  de  novo  sentencing  issues  involving
                                          

questions of  law, including the applicability  of a relevant

                    
                                

10.  Moreover, the legislative history  of the Anti-Arson Act
of   1982,  which  amends    844(h)(1)  and  other  statutory
sections,  strongly  suggests Congress'  recognition,  in the
context  of this statutory scheme, that one can "use fire" to
effect a number of criminal purposes,  specifically insurance
fraud.  See H.R. Rep. No. 678, at 2 (1982), reprinted in 1982
                                                                    
U.S.C.C.A.N. 2631,  2632 ("Fire is used  extensively not only
for  the  criminal  purposes   of  extortion,  terrorism  and
revenge, but to  conceal other crimes  such as homicide,  and
for fraud against insurance companies.").

guideline.   See id.   Because the sentencing  court enjoys a
                                

unique   vantage  point  and   has  "special  competence"  in

assessing  the  "ordinariness"  of   a  case,  we  afford  it

substantial deference in departure decisions, which we review

only for abuse  of discretion.  Koon v. United States, 116 S.
                                                                 

Ct. 2035, 2047 (1st Cir. 1996).

          The  arson  guideline provides  for  different base

offense levels  depending on the circumstances  of the crime.

Subsection (a)(1) of the guideline authorizes the application

of a base offense level of 24 if:

          the  offense  (A)  created a  substantial
          risk of death or serious bodily injury to
          any  person other  than a  participant in
          the  offense, and  that risk  was created
                                                               
          knowingly;    or    (B)   involved    the
                               
          destruction or attempted destruction of a

U.S.S.G.   2K1.4(a)(1)  (emphasis added).   Subsection (a)(2)

authorizes a lower base offense level, 20, if:

          the  offense  (A)  created a  substantial
          risk of death or serious bodily injury to
          any  person other  than a  participant in

          As  indicated  by the  underscored language  in the

text  of the arson guideline set forth above, the higher base

offense level (24) is warranted  under either the first prong

of    2K1.4(a)(1) --  the knowing  creation of  a substantial

risk of death or  serious bodily injury (  2K1.4(a)(1)(A)) --

or  the   second  prong  --  the   destruction  or  attempted

destruction of a dwelling  (  2K1.4(a)(1)(B)).  The selection

between  this base offense level and the lower level (20) set

forth in the subsequent section,   2K1.4(a)(2),  depends upon

either  the defendant's mens rea (i.e., whether or not it was
                                            

"knowing") in  creating the  requisite risk, or  the type  of
                                                           

structure involved,  i.e., dwelling or non-dwelling.   If the

fire  involved a  dwelling,  the selection  between the  base

offense levels depends on whether the defendant destroyed (or

attempted to destroy) it, or merely endangered it.

          The   defendants  offered  two  rationales  to  the

district court in support of an application of a base offense

level  of  20:  (1)  it  is  inconceivable  that  they  would

intentionally create  a substantial risk of  death or serious

bodily injury  to their family members  living directly above

Brothers Fashions; and (2) they did not destroy or attempt to

destroy  a dwelling,  but rather, a  store; and  the upstairs
                               

residences, only minimally damaged, were  merely "endangered"

incidentally to the arson offense.

                                          32


          The government countered that a  base offense level

of 24  was  warranted  because,  under  the  first  prong  of

  2K1.4(a)(1), the  defendants had only  to "knowingly,"  not

"intentionally,"  create  the   risk  of  death   or  injury.

Moreover, the government argued, the defendants satisfied the

"knowingly" requirement because they committed the arson at a

time  when they knew residents  were in the  very building to

which  they set fire.  The government argued further that the

second prong  of   2K1.4(a)(1)  warranted a level  24 because

the defendants destroyed or attempted to destroy a dwelling.

          The district court observed that a pivotal question

revolved  around  the  meaning   of  the  word   "knowingly."

  2K1.4(a)(1)(A).   The court  opined that the  definition of

"knowingly" was  "a little bit  ambiguous" in the  context of

the arson guideline.  It first observed that, "[o]bjectively,

a  rational person  perhaps should  know that  if he  set the

gasoline fire in the basement,  people living above would  be

injured."   The court,  however, further  stated  that if  it

interpreted   "knowingly"  as  "intentionally,"  it  did  not

believe that Virgilio Ruiz  intentionally put his brothers in

danger; instead, the court observed, "I think subjectively he

may have had the  foolish, but sincere belief that  this fire

could be  started, that everybody could  be quickly evacuated

                             -33-
                                          33


or  even  that the  dwelling where  they  lived would  not be

destroyed, just the store would be."13 

          The court then concluded:

               Well, I'll tell  you what I'm  going
          to do.  I'm  going to rate this as  a 22.
          There is  a  preamble to  the  guidelines
          which I cannot find right [now] that says
          if  something  doesn't perfectly  fit one
          category or another, it is permissible to
          interpolate.
               For  example, there  is  a law  that
          says if somebody  is between a minor  and
          minimal participant, you  can reduce  the
          role in the offense by 3 rather than 2 or
          4  and, in  [another  case],  I [had]  to
          study the interpolation  language at  the
          beginning of the guidelines.  It seems to
          me this is a [case] which generally falls
          between      the      two     provisions,
          [  2K1.4](a)(1)  and (a)(2),  essentially
          for  the reasons [stated  above].   And I
          think  the  fairest  and  legal[ly]  most
          appropriate   thing   to   do    in   the
          circumstances would be to interpolate and
          I'm going to rate this as a 22.14

                    
                                

13.  The court appeared to find inapplicable the second prong
of   2K1.4(a)(1)  -- "destruction or attempted destruction of
a dwelling."    2K1.4(a)(1)(B).   The court observed that the
circumstances   of  the   arson  appeared   to  involve   the
destruction of the  store, and the  endangering, but not  the
destruction,  of the dwelling.  In the apparent absence of an
intent  to destroy  the whole  building, the  court impliedly
found   the   "attempted   destruction"    alternative   also
inapplicable.     The   government  challenges   the  factual
underpinnings  of this conclusion.  Finding no clear error at
this juncture, we leave this ruling undisturbed.

14.  The court eventually adjusted Santo's base offense level
downward, from 22 to  20, for being a "minor  participant" in
the offense, see  U.S.S.G.   3B1.2(b),  which, combined  with
                            
his criminal history category I, yielded a guideline range of
33 to 41 months.  The court declined the government's request
to increase Santo's offense level by two points  for perjury.
The  court selected  a 33-month  prison  term for  the arson,
conspiracy,  and mail  fraud counts,  to be  followed  by the

                             -34-
                                          34


          On appeal, the defendants contend that the district

court  erroneously  "interpolated"  when  applying  the arson

guideline.  They  argue that if the  court found inapplicable

  2K1.4(a)(1), it should have  affixed the lower base offense

level  provided for  in   2K1.4(a)(2),  rather than  apply an

intermediate  level.   The  government  does  not appeal  the
                                                             

sentences  as calculated,  but  nonetheless  argues that  the

higher base  offense level  was clearly appropriate  and that

the   defendants,    who   benefitted   from    the   court's

"interpolation" exercise, have no basis for complaint.

          The  district  court's  use  of  "interpolation" to

affix  an intermediate  base  offense level  was an  apparent

attempt  to   invoke  a   paragraph  (now  deleted)   in  the

Introduction  to  the  pre-November  1989  Guidelines Manual.

See,  e.g.,  U.S.S.G.     1A4(b)  (1987).    The   Sentencing
                      

Commission  had  designated  "interpolation"  as  a  form  of

departure  in  which  a  sentencing  court  could  choose  an

intermediate   point   "between  two   adjacent,  numerically

oriented guidelines rules."  Id.  Effective November 1, 1989,
                                            

however, the Commission deleted that interpolation provision,

                    
                                

mandatory 60 month consecutive  term for his conviction under
18  U.S.C.    844(h)(1)  (using  fire  to  commit  a  federal
felony), for  a total of 93 months' imprisonment.  Virgilio's
base offense  level remained  at 22,  which, combined  with a
criminal  history   category  I   and  the  added   60  month
consecutive term, yielded a total range of 93-111 months.  On
the  government's recommendation,  the  court affixed  a 108-
month prison term for Virgilio.

                             -35-
                                          35


concluding "that  it is  simpler to add  intermediate offense

level  adjustments to the  guidelines where  interpolation is

most likely to be considered."  U.S.S.G. App. C, Amendment 68

(1989).  The Commission also stated, however: "This amendment

is  not intended  to preclude  interpolation in  other cases;

where appropriate, the court will be able to achieve the same

result  by use  of the  regular departure  provisions."   Id.
                                                                         

Thus, although the issue is somewhat unclear, it appears that

interpolation between guideline rules is permissible where it

could  be  properly  justified  under  the  normal  departure

procedures.

          Assuming  that  the  court essentially  effected  a

downward departure when affixing a base offense level of  22,

we  find  that because  the  district  court failed  to  make

specific findings  on the defendants'  state of mind,  we are

unable to resolve either  the defendants' contention that the

facts warranted a level 20, or the government's argument that

a  level 24  was appropriate.   Our  inability to  settle the

sentencing issue  absent such findings requires  us to remand

the case for  further findings and resentencing.   See United
                                                                         

States  v. Valencia-Lucena,  988 F.2d  228, 234-36  (1st Cir.
                                      

1993)  (remanding for  resentencing  where  sentencing  court

failed  to  make  reasonably  specific   findings  concerning

foreseeability of  drug quantity); see also  United States v.

clarification  of  sentencing  court's  specific  willfulness

findings in context of downward departure).

          In  United States  v. DiSanto,  86 F.3d  1238, 1256
                                                   

(1st Cir. 1996), we stated: 

          Given   the   structure   of  the   arson
          guidelines,     we     conclude      that
            2K1.4(a)(1)(A)   requires    that   the
                                                               
          district  court  make a  specific finding
                                                               
          that the defendant 'knowingly'  created a
          substantial  risk  of  death  or  serious
          bodily  injury,  as  opposed   to  merely
          finding  that  defendant  recklessly  (or
          negligently)  created  such a  risk which
          would    more    appropriately    trigger
          application of [  2K1.4(a)(2)]  (emphasis
          added).

Whether  or not the defendant  acted "knowingly" calls for an

inquiry into his subjective state of mind when he created the

requisite risk.   See id.  at 1255 (citing  United States  v.
                                                                     

Karlic, 997 F.2d 564, 568-69 (9th Cir. 1993)).  In this case,
                  

the court explored the various possibilities of a "knowledge"

finding, opining first that a rational person would know that

setting such  a fire would cause injury,  then observing that

Virgilio did not "intentionally" put others in danger because

he "may" have had the "foolish but sincere belief" in a swift

evacuation of  the residents.  In the  end, the court did not

make any specific findings on either of the defendants' state

of mind but, instead, resorted to interpolation.

          The   court's  reluctance  to  make  the  requisite

findings may have  been the result of the  somewhat unsettled

definition in  this circuit  of the  term "knowingly"  in the

                             -37-
                                          37


arson guideline.  See generally, DiSanto, 86 F.3d at 1256-58.
                                                    

In  DiSanto,  we  discussed   at  some  length  the  possible
                       

parameters of the word "knowingly."   See id. at 1256-58.  We
                                                         

explained  that  "'the hypothetical  knowledge  continuum' is

marked  by 'constructive  knowledge' at  one end  and 'actual

knowledge' at the other."  Id. at 1257 (quoting United States
                                                                         

v. Spinney, 65 F.3d 231, 236-37 (1st Cir. 1995)).  In between
                      

these extremes lie various "gradations," including "notice of

likelihood"  and "practically  certain."   Id.   Although  we
                                                          

expressed  our inclination  "to  conclude that  a showing  of

knowledge anywhere along this continuum satisfies application

of    2K1.4(a)(1)(A),"  we  declined to  determine  the exact

level  of knowledge required for the guideline.  Id. at 1257-
                                                                

58 (finding that government had established the somewhat high

standard of defendant's awareness that the requisite risk was

"practically certain").

          Had the district court here actually found that the

defendants  acted knowingly  when they created  a substantial

risk  of death or serious bodily injury to someone other than

themselves,  we likely would  have upheld the  finding as not

clearly  erroneous,  even  under the  stringent  "practically

certain" test.  The  evidence established that the defendants

set  fire to  a  building basement  in the  early hours  of a

winter morning, knowing that the residential units above were

occupied.  "It is difficult to imagine a clearer illustration

                             -38-
                                          38


of the knowing  creation of  a substantial risk  of death  or

serious bodily injury."   United States v. Honeycutt,  8 F.3d
                                                                

785,  787  (11th  Cir.  1993)  (finding  requisite  level  of

knowledge  where defendant, having seen people inside tavern,

threw  a  Molotov  cocktail  at the  outside  corner  of  the

building) (using "practically certain" test).  The sentencing

court,  however,  must make  such  a  finding  in  the  first

instance,  and we will not engage in that initial exercise on

appeal.

          Because  we  remand  this  case  for  findings  and

resentencing, we  think it  necessary to clarify  further the

definition of "knowingly" appearing in subsection (a)(1), but

not (a)(2), of  the arson guideline.   See U.S.S.G.    2K1.4.
                                                      

The guideline's  structure "clearly suggests that  there must

be  a  meaningful  distinction  between  the  two  sections."

DiSanto, 86 F.3d at 1256.  As we noted in DiSanto, 86 F.3d at
                                                             

1257, the Ninth and Eleventh Circuits have  adopted the Model

Penal Code's definition of "knowingly."15  In those circuits,

"a  defendant  can be  found  to have  'knowingly'  created a

substantial  risk of  death  or serious  bodily injury  under

  2K1.4 only  if the defendant  was aware that  a substantial
                                                     

risk  of  death or  serious  bodily  injury was  'practically
                                                                         

                    
                                

15.  The Seventh Circuit has also approvingly cited the Model
Penal Code's  definition of knowingly  in this context.   See
                                                                         
United States v.  Altier, 91  F.3d 953, 957  (7th Cir.  1996)
                                    
(distinguishing "knowingly" from "purposefully").

at 569 (emphasis added); accord Honeycutt, 8 F.3d at 787; see
                                                                         

also Model Penal Code   202(2)(b) (1985).16
                                 

          We agree  with our  sister circuits that  the Model

Penal Code's  definition gives due regard  to the "meaningful

distinction"  between  the   pertinent  guideline   sections.

Indeed,  we have  already held  that a  "practically certain"

finding,  which is akin  to, but something  less than, actual

knowledge,17  satisfies  the   definition  of  "knowingly."  

DiSanto,  86 F.3d at 1257-58.  Thus, we adopt the Model Penal
                   

Code absent a contrary guidelines definition.  We acknowledge

our  earlier inclination  to  include all  gradations of  the

knowledge continuum  in this context.   Id. at 1257.   To the
                                                       

extent, however, that "constructive knowledge"  requires only

                    
                                

16.  The   Model  Penal  Code's   definition  of  "knowingly"
provides that:

          A person acts knowingly with respect to a
          material element of an offense when: .  .
          .
          (ii)  if the element involves a result of
          his  conduct,  he  is  aware that  it  is
          practically certain that his conduct will
          cause such a result.

Model Penal Code    2.02(2)(b) (1985).  The  Model Penal Code
                            
further states that "[w]hen knowledge  of the existence of  a
particular fact  is an element of an  offense, such knowledge
is established if a  person is aware of a high probability of
its  existence,  unless  he  actually believes  it  does  not
exist."  Id. at   2.02(7).

knowledge."  Spinney, 65 F.3d at 237.

or  "should have  known" of  a substantial  risk, see  id. at

something  more is  needed.   For the  purposes of  the arson

guideline,   these    particular   "constructive   knowledge"

formulations  appear  to  establish  only  "recklessness"  or

"negligence," both  insufficient to  trigger the  higher base

offense level.  See DiSanto, 86 F.3d at 1256.
                                       

          On  remand, the  district  court should  articulate

specific findings of each defendant's state of mind regarding

the creation  of the risk.   In order for the  higher offense

level  to apply, the court  certainly need not  find that the

defendants  "purposefully"  or   "intentionally"  created   a

substantial risk of death or  serious bodily injury.  Rather,

the court  need find only  that Virgilio  and Santo  actually

knew that they created such risk, or were aware that the risk

was  practically certain.  If,  on the other  hand, the court

supportably finds  that one or both of them actually believed

that no substantial risk was created under the circumstances,

a  finding of knowledge would not be warranted.  See DiSanto,
