     LYNCH,  Circuit Judge.  Three men have gone to prison as

a  result of  the distribution  of  two kilograms  of cocaine

within  one thousand  feet of  a school  in Carolina,  Puerto

Rico.  Two of the men are guilty, having pled so.  The third,

Fernando Montilla-Rivera  ("Montilla"),  asserts that  he  is

innocent.    He  trusted his  fate  to  a  jury,  and he  was

convicted  of aiding and abetting  the crime, in violation of

21  U.S.C.    841(a)(1)  and 860(a), and  18 U.S.C.    2.  On

appeal, Montilla argues that the government's evidence showed

no  more than that he  was present during  the sale, and that

this "mere presence" is  insufficient to support the verdict.

He also  argues that the  trial judge erred in  denying him a

new  trial  when,  a  year  after  his  conviction,  Montilla

presented affidavits  from the  other two men,  each swearing

that Montilla was innocent.

                              I.

     We  recite the facts  as the jury  could have reasonably

found  them.  United  States v. Andrade,  94 F.3d 9,  10 (1st
                                                   

Cir.  1996).   On  March 22,  1995,  Eladio Valerio,  a  Drug

Enforcement Agency confidential informant,  made a phone call

in  search of  drugs.   He  called Miguel  Calder n-Salmiento

("Calder n"), who  would later  become a codefendant  in this

case.   In  a  taped conversation,  which  was clearly  about

arranging a drug purchase, Calder n told the informant, "Come

on down here to . . . to go over to the mechanic at 12."  The

                             -2-
                                          2


informant explained that he could not "come on down" that day

because the funds were  not ready.  There were  several other

taped  conversations  about the  deal.    At that  time,  the

mechanic  working at  the mechanic's  shop to  which Calder n

referred was Montilla.  

     A  few days  later,  on March  24, 1995,  the informant,

wired and accompanied by  DEA Agent Domingo Carrasquillo, did

meet with Calder n.  The informant and Calder n initially met

at a service station, where Calder n invited the informant to

go "see the  mechanic."   The informant  understood that  "by

seeing the mechanic," Calder n meant they would go "where the

material  or the drug was."  Agent Carrasquillo went ahead to

a shopping  center where he expected the  drug transaction to

take place.  

     Calder n  drove the  informant to  an auto  repair shop,

behind  the Metreza night club in San Ant n, which was within

one thousand  feet of a public school.  The shop was a wooden

structure  attached at one  end to the  club and open  at the

other.  There was  a small room inside  the shop; the  repair

work took place outside of this room.  

     At the shop, the informant  saw Ram n Zorrilla, who also

later became a codefendant  in this case, and Montilla.   The

informant  shook  hands  with  them, but  did  not  speak  to

Montilla.   Montilla  wore  overalls and  had  grease on  his

                             -3-
                                          3


clothes;  Zorrilla did not.  The  four men then went into the

small room.

     Once inside,  the dealing  began in earnest  between the

informant,    Calder n,   and   Zorrilla.      During   these

negotiations,  Montilla was  ten  to twelve  feet away,  just

inside the  entrance to  the room, "watching  [and] looking."

The  informant and the other  two negotiated and  agreed on a

price  of $12,100 per kilogram of cocaine.  As Montilla stood

at the entrance, still  watching, the three other men  agreed

that  if the quality of  the initial two  kilograms was high,

four more would be purchased.  At that point, Zorrilla made a

call from the room to have the cocaine delivered to the shop,

requesting "two shoes."   The informant called his "partner,"

in  reality  DEA  Agent  Carrasquillo,  to  arrange  for  the

exchange of the cocaine for cash.  While they waited  for the

delivery, and  with Montilla still at  the entrance, Calder n

loudly commented on the quality of the cocaine: "[H]ell, pure

cocaine." ("Diablo, coca na  pura.") 

     The  drugs  were delivered  to  the shop.    As Montilla

watched, the informant tasted the cocaine and pronounced that

it was good  and that the "deal was on."   The informant went

off  with  Calder n  to  the  shopping  center  to  meet  the

informant's  partner,  who  had  the  money.    Montilla  and

Zorrilla stayed behind with the cocaine at the shop.  

                             -4-
                                          4


     At the shopping center,  the partner showed Calder n the

cash.    The men agreed  that Calder n would  return alone to

the repair  shop, and that  ten minutes later,  the informant

and his partner would bring the money for the exchange.  Back

at  the shop, the "partner"  agent told the  informant to get

out of the  car, go into the  mechanic's shop, and bring  out

the  people involved in the  transaction.  The informant went

into the  small room,  told Montilla, Zorrilla,  and Calder n

that "someone was waiting for them in the car, [and] for them

to  take the material and give them the money."  Zorrilla and

the informant  approached the  car and asked  the partner  to

come into the shop, where they would make the  exchange.  The

partner refused and said the delivery should be made outside.

Zorrilla  complied and  went back  into the  shop to  get the

drugs.   The three men -- Calder n, Zorrilla, and Montilla --

came  back  toward the  street,  with  Calder n carrying  the

drugs.  Montilla and  Zorrilla had moved to where  they could

watch  the transaction  from  the front  of  the shop,  about

thirty feet away from the partner's car.  

     All  three  men  were  arrested where  they  stood  when

Calder n  made the delivery.   At the time  of arrest, others

were in the shop, including the shop owner and a visitor.  At

no time during the transaction did the informant see Montilla

working on a car. 

                             -5-
                                          5


     As the  government conceded,  its videotape of  the drug

delivery and  arrest did not show Montilla; nor do any of the

audiotapes   of  the   transactions  contain   recordings  of

Montilla's voice.  In fact, the government at trial described

Montilla as  a minor  participant, but a  knowing participant

nonetheless, who had acted as a lookout.

     Montilla's  defense was mistaken identity, that Zorrilla

was the  "mechanic" referred to in  the initial conversation.

Zorrilla was a mechanic and had worked at this shop some four

months earlier.  Calder n was not a mechanic.  

     Montilla did not  testify at trial.  His  first witness,

the shop  owner, testified that  Montilla had worked  for him

there for  about a month, that Zorrilla,  not Montilla, lived

in the  room at  the shop,  and that  Montilla had  just been

doing his job, repairing a car  that was to be picked up that

day.  The owner also said that Zorrilla had worked for him at

the shop for over a year, but had not worked there during the

previous four months.   The owner explained that just  before

Montilla  went outside to the front of  the shop where he was

arrested, Montilla had  said that he was stepping  outside to

have a soft drink  and to smoke.  Montilla's  second witness,

who was visiting the shop during the incident, testified that

he  had seen  Montilla  working on  a  car until  he  stepped

outside to have  a cigarette  since the owner  did not  allow

smoking inside the shop.  The jury convicted Montilla, and he

                             -6-
                                          6


was  sentenced to  five years  in prison  and eight  years of

supervised release.

     Montilla originally  planned to call  both Zorrilla  and

Calder n  as witnesses.  The two entered guilty pleas on June

27, 1995.   On June 29, 1995, Montilla filed a motion to have

the Marshal's  Service produce  his codefendants  to testify.

The  court  granted  the  motion, but  the  two  codefendants

informed the court, on advice  of and through their  counsel,

that  they would  not testify  for Montilla.     Montilla was

convicted  on July 1, 1995.   Calder n and  Zorrilla were not

sentenced until September 26, 1995.  

     On  July 17,  1996, Montilla  filed a  motion for  a new

trial under  Fed. R. Crim. P. 33.  The motion attached nearly

identical affidavits from Zorrilla  and Calder n.  Zorrilla's

affidavit said in relevant part:

          I never knew Mr. Fernando Montilla as qa [sic] drug
     dealer nor that  he was  or has been  involved in  drugs
     [sic]  dealing but  as  a good  har  [sic] worker  as  a
     mechanic.

          I state that Mr.  Fernando Montilla was not involve
     [sic]  in the  drugs [sic]  transaction occurred  on the
     date of my arrest and for which I pled guilty.

Calder n's affidavit stated in part:

          At  no  time,  I  have [sic]  been  aware  that Mr.
     Fernando  Montilla  has  been  involved in  any  illegal
     activity  like  the  one  for which  he  was  convicted,
     possession with intent to  distribute cocaine.  In other
     words, Mr.  Fernando Montilla  was not involve  [sic] in
     the offense for which I pled guilty.

          At all time [sic] I knew Mr. Fernando Montilla as a
     hard mechanic worker and anything [sic] else.

                             -7-

Citing United States v. Tibolt, 72 F.3d 965 (1st Cir.), cert.
                                                                         

denied, 116 S. Ct. 2554 (1995), the district court denied the
                  

new trial motion on the grounds that the witnesses were known

and available at  the time of  trial.  Thus,  in the  court's

view, Montilla did not meet the requirements of Fed. R. Crim.

P. 33.

                             II.

Sufficiency of the Evidence
                                       

     In our sufficiency of  the evidence review, we determine

whether,   drawing   all   reasonable   inferences   in   the

government's favor, a rational jury could find guilt beyond a

reasonable doubt.  Andrade, 94 F.3d at 12.
                                      

     Montilla argues that the jury was faced with two equally

likely scenarios, one of which was  that he was innocent.  He

asserts  that under United States v. Andujar, 49 F.3d 16 (1st
                                                        

Cir.  1995), this  is insufficient  to meet  the government's

burden  of   proof  of  guilt  beyond   a  reasonable  doubt.

Montilla's  statement of  the  law is  correct.   Id.  at  22
                                                                 

("When  a  jury is  confronted . . . with  equally persuasive

theories of  guilt and  innocence, it cannot  rationally find

guilt  beyond  a  reasonable  doubt.").    However,  Montilla

understates the case against him.

     The guilt  of Zorrilla and  Calder n is admitted.   When

Calder n and Zorrilla were negotiating the deal at  the shop,

Montilla  was constantly  present.  Criminal  conspirators do

                             -8-
                                          8


not often "welcome  innocent nonparticipants as witnesses  to

their crimes."   United  States v. Batista-Polanco,  927 F.2d
                                                              

14, 18 (1st  Cir. 1991);  see also United  States v.  Cuevas-
                                                                         

Esquivel, 905  F.2d 510, 515 (1st Cir.  1990).  No effort was
                    

made  to keep the illicit deal from Montilla's ears.  Indeed,

Zorrilla loudly  bragged about the  purity of the  cocaine in

front of Montilla. 

     Still,  mere  association  with  a   principal  or  mere

presence while  criminal activity is  going on around  one is

not  enough  to  establish  aiding and  abetting,  even  when

combined  with knowledge that a crime will be committed.  See
                                                                         

United States  v. Luciano-Mosquera,  63 F.3d 1142,  1150 (1st
                                              

Cir.  1995),  cert.  denied, 116  S.  Ct.  1879  (1996).   As
                                       

Montilla points out, this was a crime-ridden neighborhood and

knowledge by  Montilla that those around  him were committing

crimes  does  not necessarily  mean  that he  was  aiding and

abetting those crimes.  

     While knowledge is certainly  an element of the offense,

id.,  (and  the  facts   here  abundantly  show   knowledge),
               

something  more, some action to assist the crimes, is needed.

See  id.   To convict  Montilla of  aiding and  abetting, the
                    

government had  to prove that his  codefendants committed the

crime,  and  that  Montilla  associated  himself   with,  and

participated in  the drug transaction as  something he wished

                             -9-
                                          9


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

United States v. Ruiz, 105 F.3d 1492, 1499 (1st Cir. 1997).
                                 

     The  government says  that  the something  more is  that

Montilla  acted as  a lookout.   Several inferences  from the

evidence  support the  government's position.   The  first is

that Montilla was at the entrance to  the small room where he

could  act as a lookout while the drug deal negotiations were

being conducted and was  not in the shop repairing cars.  The

second is that, when the  informant told the men it was  time

to deliver the drugs to his partner, all three men, including

Montilla, left  the small room to go out toward the car.  The

third is that Montilla,  who did not have the  drugs, stopped

just outside the shop, and from that vantage watched.  He was

well-situated to  act as  a lookout,  and an  arresting agent

thought that was exactly what Montilla was doing.

     The evidence is thin,  but not so thin as  to invalidate

the jury's reasonable assessment that Montilla is guilty.

New Trial Motion
                            

     The  district  court's denial  of the  motion for  a new

trial  is reviewable only for a manifest abuse of discretion.

Andrade, 94 F.3d at 14.   A district court's power to order a
                   

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

acquittal.  Ruiz, 105 F.3d at 1500.
                            

     Rule  33  of the  Federal  Rules  of Criminal  Procedure

authorizes a district court to grant a new trial "if required

                             -10-
                                          10


in the interest of justice."1  Where, as here,  the motion is

based   on  new  or   previously  unavailable  evidence,  the

defendant  has  to  establish  that "the  evidence  was:  (i)

unknown or unavailable at the time of trial, (ii) despite due

diligence, (iii)  material, and (iv)  likely to result  in an

acquittal upon retrial."  Tibolt, 72 F.3d at 971. 
                                            

     Although the new statements by the two principals of the

drug transaction that Montilla is innocent appear facially to

satisfy the third and fourth elements of the test,2 our focus

is  on the  first element  of the test.   The  district court

denied  the motion on the  ground that the  evidence was both

known and available.   Similarly, the government,  apparently

conceding  the third  and  fourth elements,  argues that  the

                    
                                

1.  Fed. R. Crim. P. 33 states in relevant part:
     The  court on a motion  of a defendant  may grant a
     new  trial to  that  defendant if  required in  the
     interest  of justice. . . .    A motion  for a  new
     trial  based  on  the  ground  of  newly discovered
     evidence  may be  made  only before  or within  two
     years  after final  judgment, but  if an  appeal is
     pending  the court  may  grant the  motion only  on
     remand of the case.

2.  The  statements are material and appear to give rise to a
"reasonable" probability  of acquittal upon retrial.   United
                                                                         
States v.  Sepulveda, 15 F.3d 1216, 1229 (1st Cir. 1993).  In
                                
saying  this, we  are  taking account  of  the ambiguity  and
thinness  of  the inculpatory  evidence  and  are taking  the
exculpatory  statements at  face value.   Whether  the latter
would  retain  their  force  after  close  examination  is  a
different  question; as we note below, a hearing might cast a
different light on these statements.

                             -11-
                                          11


testimony  was neither  unknown,  nor unavailable.   It  also

asserts that Montilla did not exercise due diligence.  

     In  this  lies  the  problem.    Both  the  government's

arguments   and  the  district  court's  ruling  assume  that

Zorrilla  and  Calder n  were   "available"  to  testify   at

Montilla's trial.   But  Montilla, who, it  facially appears,

had diligently attempted to  secure their testimony,3 did not

have the  power to  compel them  to testify  at his trial  in

light of  their Fifth Amendment privileges  once they changed

their minds about testifying.

     Montilla's  trial commenced on  June 27, 1995.   On that

same day, Calder n  and Zorrilla entered pleas  of guilty and

the  court  accepted  their  pleas.    Their  sentencing  was

deferred until  September, 1995.   Calder n's  and Zorrilla's

counsel  each advised his client not  to testify for Montilla

because the  testimony might incriminate them  with regard to

other transactions  and  because the  men still  had to  face

sentencing proceedings.   Exercising their  privilege against

self-incrimination,  Calder n and Zorrilla informed the court

that they would not testify, and they were excused.   

                    
                                

3.  According  to  Montilla's   trial  attorney's   affidavit
submitted in support of the motion for a new trial, he  tried
on two separate occasions to interview Zorrilla and Calder n,
but they refused to  give him any information.  (The dates of
these  attempts  are  unclear).    Despite  not  knowing  the
contents of their testimony, the trial attorney moved to have
Zorrilla  and Calder n  subpoenaed  to testify.   His  client
Montilla  insisted that  the  testimony would  exculpate  him
rather than hurt him.

     We have recognized that an unsentenced defendant who has

pled guilty retains a legitimate protectable  Fifth Amendment

interest  as  to  matters  that could  affect  his  sentence.

(1st Cir. 1983);  see also  Estelle v. Smith,  451 U.S.  454,
                                                        

461-63 (1981)  (state's efforts to compel  criminal defendant

to  testify  at  sentencing  phase  of  capital  trial  would

contravene   Fifth  Amendment).     Further,   the  potential

importance of  the presentence phase  of criminal proceedings

to a defendant is highlighted by Fed. R. Crim. P. 32(e) which

expressly  permits  a defendant  to  withdraw  a guilty  plea

before  a sentence is imposed  by showing "any  fair and just

reason."   It was an error  of law for the  district court to

hold that the testimony of these witnesses was  available per

se.  

     This  then  poses  a  legal  question,  not   explicitly

addressed  by the  government.   Rule  33  permits new  trial

motions to be filed  within two years only if the evidence is

"newly  discovered."     If   the  evidence  is   not  "newly

discovered," and  the  motion was not filed within  the seven

days  otherwise  required,  then  the  district  court  lacks

jurisdiction to hear  the motion.  United  States v. DiSanto,

     The  legal  question is  whether  exculpatory affidavits

from codefendants who  did not testify at trial  because they

exercised their  Fifth Amendment privileges  may ever qualify

as "newly discovered" evidence within the meaning of Rule 33.

Most other circuits have  expressed hostility to this notion,

usually on the  ground that  the defendant was  aware of  the

potential  testimony at  trial,  even if  that testimony  was

unavailable  due to  assertions of  privilege.   These courts

have  held that such testimony is not newly discovered.  See,
                                                                        

e.g., United States v.  Theodosopoulos, 48 F.3d 1438, 1448-50

731, 739-40 (9th Cir. 1981).

     We believe the question is resolved affirmatively by our

precedent.  This circuit  has, for almost twenty years,  held

that the  "newly discovered" language of  Rule 33 encompasses

evidence  that  was "unavailable."    See  Vega Pelegrina  v.
                                                                     

United States, 601 F.2d 18, 21 (1st Cir. 1979).  In this, our
                         

test has differed from  that of other circuits, as  the cases

cited  above demonstrate.    Indeed, in  Vega Pelegrina,  the
                                                                   

newly discovered evidence was  the testimony of a codefendant

who  had refused  to testify  for defendant  at trial,  or to

limitations had run.  Id.
                                     

     This court has adhered to the four part test outlined in

United States v. Wright,  625 F.2d 1017 (1st Cir.  1980), for
                                   

almost two decades, saying that the first question is whether

the evidence "was unknown or unavailable to the  defendant at
                                                    

time of trial."   Id.  at 1019 (emphasis  added); see,  e.g.,
                                                                        

United  States  v. Ortiz,  23 F.3d  21,  27 (1st  Cir. 1994);
                                    

United States v. Benavente Gomez, 921 F.2d 378, 382 (1st Cir.
                                            

1990); United States v. Glantz, 884 F.2d 1483, 1486 (1st Cir.
                                          

1989); United States v.  Martin, 815 F.2d 818, 824  (1st Cir.
                                           

1987).  This panel is not  free, on its own, to alter circuit

precedent absent  some intervening  reason such as  a Supreme

Court decision or new legislation.  

     Furthermore, given the  "[i]n the interests of  justice"

standard  of  Fed.   R.  Crim.  P.  33,  there  seems  little

distinction  between evidence  which  a defendant  could  not

present because he  did not know of it  and evidence which he

could not present because the witness was unavailable despite

exercising due diligence.   At least in the context  of newly

available evidence from  one not a codefendant,  at least two

circuits  appear to agree.  See United States v. Garland, 991
                                                                    

F.2d  328, 335  (6th  Cir. 1993)  (ordering  new trial  where

"although the  defense knew of  [witness's] existence  before

and during  the trial,  [the witness]  was not located  until

                             -15-
                                          15


after the trial."); United  States v. Ouimette, 798  F.2d 47,
                                                          

51-52 (2d  Cir. 1986)  (ordering hearing on  new trial  where

witness,  while  known of  at  trial,  was unavailable  after

police allegedly pressured him not to testify).

     We  believe  the better  rule  is  not to  categorically

exclude the testimony of a codefendant who asserted his Fifth

Amendment privilege  at trial  under the  first prong but  to

consider it, albeit with great skepticism, in  the context of

all prongs of our four part test.  It is true that there is a

greater need for caution in considering Rule 33 motions where

the   new  evidence   comes  from   a  codefendant   who  was

"unavailable"  at  trial because  he  chose  to exercise  his

privilege.   See DiBernardo, 880 F.2d at  1224; United States
                                                                         

v. Jacobs, 475 F.2d 270, 286 n.33 (2d Cir. 1973).   It is not
                     

unusual for the obviously guilty codefendant to try to assume

the  entire guilt.  United States v. Alejandro, 527 F.2d 423,
                                                          

428 (5th Cir. 1976).  A convicted,  sentenced codefendant has

little  to  lose  (and perhaps  something  to  gain)  by such

testimony.  United States  v. Freeman, 77 F.3d 812,  817 (5th
                                                 

Cir.  1996).   "Such  testimony  [by sentenced  codefendants]

would be untrustworthy and should not be encouraged."  United
                                                                         

States  v.  Reyes-Alvarado, 963  F.2d  1184,  1188 (9th  Cir.
                                      

1992).

     Nonetheless, there  is, here, at least  a facial showing

of  compliance with  the other  prongs sufficient  to warrant

                             -16-
                                          16


further inquiry.  On its face, the proffered testimony in the

affidavits is material, and the testimony, if believed, could

lead  to a  different  outcome, especially  in  light of  the

government's  sufficient,  but  underwhelming,  case  against

Montilla.  See  Benavente Gomez, 921 F.2d at 383 ("It is true
                                           

that  where  the  trial  evidence was  noticeably  thin,  new

exculpatory evidence may be  of increased importance.").  The

new  testimony, while it may  not be true,  is not inherently

implausible.    And we  note  that  Montilla has  steadfastly

maintained his  innocence, even through  sentencing, at  some

cost.    Because  he  refused  to  acknowledge  that  he  had

committed  a crime,  Montilla  was  ineligible  for  sentence

reductions for  acceptance of  responsibility under  the U.S.

Sentencing Guidelines.

     The term  "on its face"  is used  deliberately here  and

with no  suggestion  that the  codefendants' newly  available

testimony  is true.  That  the codefendants waited  a year to

come  forward   hardly  supports   the   strength  of   their

assertions.  But there is enough to commit the matter back to

the  district   court,  which  is  itself,   under  the  law,

responsible for weighing the factors under Rule 33:

     Motions  for  new   trial  are   directed  to   the
     discretion of the trial court.  In considering such
     a motion,  the court has  broad power to  weigh the
     evidence  and assess  the credibility  of both  the
     witnesses who  testified at trial  and those  whose
     testimony constitutes "new" evidence.

785 F.2d 1 (1st Cir. 1986), and  remand to the district court

to  reconsider the  motion  for  a  new  trial  and  to  hear

evidence.   There  is no  suggestion that  such hearings  are

required  in  the usual  course; they  are  not.   Cf. United
                                                                         

States v. Kearney, 682  F.2d 214, 218 (D.C. Cir.  1982).  Had
                             

the district  court itself  ruled otherwise on  the issue  of

unavailability, it might have  chosen to have a hearing.   We

think  it wiser  here for the  district court to  hold such a

hearing given the unusual  combination of circumstances here.

Montilla's conviction rests almost entirely  on the testimony

of  the  DEA  informant.    Neither  the  videotape  nor  the

audiotape directly  incriminate Montilla.   The reference  on

the  audiotape   to  the  mechanic  could   equally  well  be

understood  to refer to the location of  the deal, and not to

the role of the mechanic.   Only the informant places him  in

the  small  room;  Montilla's  other  witnesses  say  he  was

repairing  a car.    A hearing  will  be helpful4  where  the

matters  presented  by  the  proffer  are  not  "conclusively

refuted as to the alleged  facts by the files and  records of

the case."   United States  v. Carbone, 880  F.2d 1500,  1502

Neither Calder n nor Zorrilla testified before -- this is not

a recantation of  testimony situation where the court has had

an opportunity to assess credibility.5

     We believe  the district court should,  after a hearing,

reconsider whether,  as Rule  33 provides, "the  interests of

justice require a new trial."  See Ouimette, 753 F.2d at 192-

     As  already  observed, we  disagree  with  the decisions

treating the  belated  statements of  codefendants  aimed  at

exculpating the moving defendant as per se insufficient under

Rule 33.   But  we  share the  general skepticism  concerning

those statements, and the present opinion by no means confers

any automatic right in such a case to  a new trial or even to

a hearing.   Our judgment here turns on unusual circumstances

including the  weakness of the government's  case against the

defendant, significant  efforts to procure  the codefendants'

testimony  before  his  own  conviction,  and  the  plausible

explanation as to why the evidence was not available earlier.

     The  case is  remanded for  proceedings  consistent with
                                       

this opinion.
