Before POSNER, RIPPLE, and SYKES, Circuit Judges.
RIPPLE, Circuit Judge. Following an extensive sting opera‐
tion by federal law enforcement of a drug distribution ring in
Chicago, Charles Tankson was indicted on three counts of dis‐
tributing 100 grams of heroin and one count of distributing a
detectable amount of heroin, both in violation of 21 U.S.C.
§ 841(a)(1). He entered a written plea declaration without a
plea agreement. At sentencing, the Government introduced
Mr. Tankson’s post‐arrest statement to authorities in order to
2 No. 14‐3787
establish significant additional drug quantities as relevant
conduct. The district court credited the statement and, on the
basis of the newly established drug quantities, both increased
his offense level under the quantity table and determined that
he was subject to the career offender guideline. The court cal‐
culated a guidelines range of 360 months to life but sentenced
him below the applicable guidelines range to 228 months’ im‐
prisonment. Mr. Tankson now appeals his sentence. He chal‐
lenges the district court’s reliance on his post‐arrest statement
in determining his relevant conduct. He also contends that the
court, in calculating his criminal history category, erred in in‐
cluding a 1995 conviction. We conclude that the district court
was entitled to credit his statement and to consider the 1995
conviction. Accordingly, we affirm the judgment of the dis‐
trict court.
I
BACKGROUND
A.
In 2012 and 2013, the FBI investigated a drug and gun traf‐
ficking operation headed by Walter Blackman, a member of
the Black Disciples gang. Blackman’s operation distributed
heroin, powder cocaine, and crack in an area on the far south
side of Chicago. The FBI’s investigation employed confiden‐
tial sources, controlled buys, wiretaps of Blackman’s phones,
traditional surveillance, and other information to uncover the
scope of Blackman’s activities and to identify the individuals
involved in his network. In the course of this investigation,
the FBI identified Mr. Tankson as Blackman’s heroin supplier.
On four occasions between November 2012 and January 2013,
No. 14‐3787 3
the FBI became aware of transactions between Mr. Tankson
and Blackman. Each involved at least 100 grams of heroin.
The FBI intercepted calls arranging these purchases and sur‐
veilled or otherwise monitored the actual exchanges. On at
least one occasion, Blackman resold the product to a confiden‐
tial informant; subsequent testing confirmed the presence of
heroin. In April 2013, Mr. Tankson was one of eighteen indi‐
viduals arrested on charges related to Blackman’s operation.
Once in custody, Mr. Tankson waived, orally and in writ‐
ing, his right to consult with an attorney under Miranda v. Ar‐
izona, 384 U.S. 436 (1966). FBI Special Agents Ward Yoder and
Joshua Rongitsch interviewed him on April 4, 2013. In the in‐
terview, he gave the agents significant details about his rela‐
tionship with Blackman’s operation. The interview was not
recorded, but was summarized by the agents in a report
drafted the following day.
Mr. Tankson told the agents that he and Blackman had
grown up together and that both were members of the Black
Disciples gang. He admitted to participating in the four trans‐
actions ultimately charged in the indictment and indicated
that three of them involved 100 grams of heroin and that the
fourth involved 150 grams. When agents played the taped
conversations for Mr. Tankson, he identified his voice and
Blackman’s, explained code words, and described his trans‐
actions in detail. He identified a photo of heroin packaged
and sold to Blackman. He also described his being stopped by
law enforcement after a sale to Blackman in which the author‐
ities had seized $3,500 in drug proceeds.
In addition to his statements about his relationship with
and sales to Blackman, Mr. Tankson also gave statements
about his own heroin suppliers and described more extensive
4 No. 14‐3787
trafficking activities. He stated that he had sold marijuana
growing up, but began selling powder cocaine and heroin af‐
ter meeting “‘a Mexican man’” at an auto repair shop near I‐55
and Western Avenue in Chicago.1 Although he described the
shop as three blocks south of I‐55 on Western, Mr. Tankson
could not locate the shop on a map or provide any further de‐
tail. For a few months after their initial meeting, the “Mexican
man” sold Mr. Tankson marijuana, and, when Mr. Tankson
earned his trust, began selling him powder cocaine. Mr. Tank‐
son admitted to purchasing roughly 1.5 kilograms of powder
cocaine from this supplier, until the supplier was robbed of
proceeds and subsequently ceased dealing drugs. The sup‐
plier then introduced Mr. Tankson to a second supplier, again
at the auto repair shop.
Mr. Tankson met the second supplier only once. He de‐
scribed him as Mexican, short, thin, and with a short, black,
military‐style haircut. The two men communicated by T‐mo‐
bile prepaid drop phones that were changed on a frequent ba‐
sis at the supplier’s request. When Mr. Tankson wanted to
make a purchase, he would call the supplier’s phone number
and would be given a time and location for the buy. He re‐
called using a Mexican country code to place the calls, alt‐
hough he could not recall what the code was. He no longer
had the phone with the second supplier’s number in his pos‐
session because he had ceased heroin dealing three months
earlier, after the police stopped him and seized the $3,500.
Mr. Tankson stated that he would only place an order for as
much heroin as he could sell on a specific day because he did
not want to store any additional product. He estimated that
1 R.48‐3 at 3.
No. 14‐3787 5
he placed 100 orders with this second supplier over two years,
each for between 300 and 400 grams of heroin. He purchased
the heroin at $6,500 per 100 grams, which he then resold at
$8,000. The supplier changed couriers often, but they were
generally other Mexican men in their forties, driving
minivans with car seats or plain work trucks. Mr. Tankson
said that the buys occurred in vehicles by window‐to‐window
transactions at the Ford City Mall in Cicero, Illinois. He
stopped all trafficking activity in January 2013, after the police
stopped him with the proceeds of a sale to Blackman.
B.
On May 2, 2013, Mr. Tankson was charged in a four‐count
indictment with distribution of heroin in violation of 21 U.S.C.
§ 841(a)(1): three counts of distribution of 100 grams or more
of heroin and one count of distribution of a detectable amount
of heroin.
During his pretrial proceedings, Mr. Tankson filed a mo‐
tion to suppress his post‐arrest statement confessing to the
charged offenses. He contended that he had not received ad‐
equate Miranda warnings and had not made many of the
statements contained in the agents’ report. Indeed, he testified
that, in his numerous arrests, he never had been advised of
his Miranda rights by any law enforcement officer. He admit‐
ted trafficking marijuana, but denied involvement in heroin
trafficking. The court held a hearing at which Mr. Tankson
and the interviewing officer, Special Agent Ward Yoder, each
testified. Following the hearing, the court denied the motion
and made a specific finding that Agent Yoder had testified
credibly and Mr. Tankson had testified falsely. Accordingly,
6 No. 14‐3787
it concluded that the Government had proved by a prepon‐
derance of the evidence that adequate warnings had been pro‐
vided and that Mr. Tankson had knowingly waived them.
Two days before his trial was set to begin, Mr. Tankson
entered a written plea on all charges, including admitting the
factual basis for the four charged heroin sales. He was silent
with respect to the remainder of his prior confession.
The presentence investigation report (“PSR”) credited the
post‐arrest statement and concluded that Mr. Tankson had
distributed 427.1 grams of heroin to Blackman and an addi‐
tional thirty kilograms to other customers between 2011 and
2013. The PSR identified all of the sales as part of an ongoing
pattern of conduct. Although his sales were not all related to
Blackman and his particular ring, they all used a common ac‐
complice (the second supplier) and an identical method and
had an identical purpose. The probation officer concluded
that the connections were sufficient to draw the additional
thirty kilograms within the relevant conduct guideline,
U.S.S.G. § 1B1.3(a)(2), which resulted in a base offense level of
38. The PSR also denied credit for acceptance of responsibility
and instead applied a two‐level enhancement for obstruction
of justice because Mr. Tankson had lied about the extent of his
criminal conduct in his suppression hearing testimony and
had delayed his plea until the eve of trial. The PSR found that
his 12 criminal history points qualified him for category V, but
also found him to be a career offender under § 4B1.1(a) based
on two predicate controlled substance convictions. His of‐
fense level was therefore 40, with a criminal history category
of VI. The resulting Guidelines range was 360 months’ to life
imprisonment.
No. 14‐3787 7
At sentencing, Mr. Tankson called Special Agent Yoder as
well as a private investigator hired by the defense. The inves‐
tigator testified that there were no auto body shops within the
vicinity that Mr. Tankson identified in his post‐arrest state‐
ment. On cross‐examination, the prosecutor clarified that
Mr. Tankson’s statement had referenced an auto repair shop,
and the investigator admitted that there was one such shop
four blocks from the intersection of I‐55 and Western Avenue.
(Mr. Tankson had said three.) Mr. Tankson’s counsel asked
Special Agent Yoder numerous questions about the degree of
follow‐up given to the details of Mr. Tankson’s statement,
such as whether he had looked for a tire shop or tried to iden‐
tify the suppliers or their phone numbers. Special Agent
Yoder confirmed that they had not expanded their investiga‐
tion of the Blackman enterprise and their existing thirty tar‐
gets to include Mr. Tankson’s suppliers. The agent said that
the decision to circumvent the investigation was a resource
issue. He did state, however, that he believed Mexican coun‐
try codes had been located on the three or four phones seized
from Mr. Tankson at the time of his arrest.2
Mr. Tankson’s counsel argued that, because the relevant
conduct had become the primary driver at sentencing, the
court could use a higher standard of proof than preponder‐
ance of the evidence if it chose. He also contended that the
Government had made no attempt to corroborate Mr. Tank‐
son’s statements in the post‐arrest interview. Further, he ar‐
gued that the standard is reliability, and “[j]ust because
Mr. Tankson said it …, allegedly said it, if you find that he
2 See R.157 at 43–44 (Sent. Tr.).
8 No. 14‐3787
said it, doesn’t mean it is reliable.”3 He also argued that a com‐
mon scheme or plan is not established simply because the de‐
fendant engaged in other drug transactions, citing United
States v. McGowan, 478 F.3d 800 (7th Cir. 2007).4
The Government argued that the information was reliable
because Mr. Tankson’s statement generally was corroborated.
First, his criminal record showed a period of drug trafficking
stretching back more than a decade. Second, various specific
details were confirmed independently by other evidence in‐
cluding the cash amounts he claimed were involved, the drug
quantities involved in the charged transactions, and the use
of drop phones to contact his supplier. The Government also
maintained that Mr. Tankson’s ability to access large quanti‐
ties of heroin in short periods of time suggested that he had
an ongoing relationship with a supplier. Mr. Tankson’s state‐
ments also matched his personal details regarding his wife,
his parents, and his gang affiliation. In the Government’s
view, his truthfulness about these matters tended to suggest
that he also spoke truthfully to the officers when he described
his relationship with the suppliers and with Blackman. Fi‐
nally, the Government submitted that because the statement
was against his own interest it should be deemed more relia‐
ble.
The district court, using the preponderance standard, de‐
termined first that Mr. Tankson actually had made the post‐
arrest statement and that Agent Yoder had testified credibly
about the interview. The court, noting that it already had
3 Id. at 61.
4 Id. at 63.
No. 14‐3787 9
found at the suppression hearing that the procedures fol‐
lowed by Agent Yoder were appropriate, also found the state‐
ment reliable because it was given in a “noncoercive environ‐
ment.”5 In the court’s view, that consideration increased the
reliability of the statement “because ordinarily people do not
make incriminating statements about themselves unless it is
true.”6 The court concluded that Mr. Tankson in fact did traf‐
fic the thirty to forty kilograms of heroin set forth by the PSR.
Turning to the legal standard for relevant conduct, the
court concluded that it was “part of a common scheme or plan
or, at the very least, the same course of conduct.”7 The court
relied on the fact that it involved the same drug, from the
same supplier, over the same timeframe as the charged con‐
duct.
Addressing Mr. Tankson’s eligibility for the career of‐
fender enhancement, the court looked at two Illinois con‐
trolled substance convictions, including one for which
Mr. Tankson had completed his prison term in July 1997. Un‐
der U.S.S.G. § 4A1.2(e)(1), a predicate offense can be counted
only if the offense or the defendant’s incarceration for the of‐
fense occurred within fifteen years of the present offense. De‐
fense counsel argued that this earlier predicate was too old to
qualify because Mr. Tankson’s release from prison had oc‐
curred fifteen years and four months before the date of the
first charged offense. The court disagreed with this argument
5 Id. at 77.
6 Id.
7 Id. at 79.
10 No. 14‐3787
and counted both state offenses because the earlier state of‐
fense had occurred within fifteen years of the earliest relevant
conduct related to the crime for which he was being sentenced.
Accordingly, the court determined that the enhancement ap‐
plied.
Finally, the court concluded that Mr. Tankson was not en‐
titled to a reduction for acceptance of responsibility and in‐
stead would receive, on the basis of his false testimony at the
suppression hearing, an enhancement for obstruction. Be‐
cause of an amendment to the guidelines after the PSR was
drafted, Mr. Tankson’s base offense level was 36, and his total
offense level was 38. The court determined that it was appro‐
priate to sentence him as a career offender (criminal history
category VI), but noted as well that, even without that device,
his range at category V would be the same—360 months’ to
life imprisonment.
The Government requested a below‐guidelines sentence
of twenty years. Mr. Tankson requested the ten‐year manda‐
tory minimum. After reviewing the § 3553(a) factors, includ‐
ing Mr. Tankson’s support of twelve children,8 his criminal
history, and his accountability for “an enormous quantity of
a powerfully addictive and destructive drug” that translated
to “tens of thousands of individual uses,” the court imposed
a below‐guidelines sentence of nineteen years or 228 months’
8 The written record of his post‐arrest statement and the Government’s
brief in this case state that Mr. Tankson has eleven children. As Mr. Tank‐
son’s testimony at sentencing and the PSR make clear, he has twelve chil‐
dren. Compare Appellee’s Br. 39, with R. 157 at 110.
No. 14‐3787 11
imprisonment as well as both standard and special conditions
of supervised release.9
Mr. Tankson now challenges whether the additional drug
quantities accepted at sentencing were based on reliable evi‐
dence, whether those amounts were related to the offenses of
conviction such that they were properly considered relevant
conduct, and whether he was subject to the career offender
enhancement.
II
DISCUSSION
Mr. Tankson challenges the portion of his sentence based
on the additional relevant conduct found by the court, specif‐
ically, distribution of thirty additional kilograms of cocaine
over the 400 grams involved in his offense of conviction. He
contends that his post‐arrest statement, memorialized in
Agent Yoder’s report, is neither reliable nor sufficient to carry
the Government’s burden. In any event, he continues, the
statement does not establish the relationship to the charged
conduct necessary to satisfy the relevant conduct guideline,
U.S.S.G. § 1B1.3(a)(2).
The standards governing our review of sentencing ques‐
tions are well established. A sentencing court must always
“begin all sentencing proceedings by correctly calculating the
applicable Guidelines range.” Gall v. United States, 552 U.S. 38,
49 (2007). As part of the proper guidelines calculation, when
drug quantity is at issue, the sentencing court must make a
9 R.157 at 112.

drug quantity finding. See United States v. Cooper, 767 F.3d 721,
731 (7th Cir. 2014); United States v. Claybrooks, 729 F.3d 699,
706 (7th Cir. 2013). We review the district court’s quantity
finding under the highly deferential clear‐error standard.
Claybrooks, 729 F.3d at 706; United States v. Longstreet, 567 F.3d
911, 924 (7th Cir. 2009).
A.
We begin with Mr. Tankson’s challenge to the statement’s
reliability.10 In a shift from his position at sentencing, he no
longer contends that the post‐arrest statement, as reported by
Special Agent Yoder, is not an accurate representation of his
statements to authorities.11 He now contends that his own vol‐
untarily given statement, taken on its face, is not sufficiently
10 Although Mr. Tankson’s brief quotes United States v. Morrison, 207 F.3d
962, 968 (7th Cir. 2000), for the proposition that “[w]e will not allow the
disparity between conduct disclosed at sentencing to enhance a defend‐
ant’s sentence to the degree that the sentencing hearing becomes a tail that
wags the dog of the substantive offense,” Appellant’s Br. 14 (internal quo‐
tation marks omitted), he does not contend that the district court could
not base the sentence on a quantity derived primarily from relevant, as
opposed to charged, conduct. See United States v. Johnson, 342 F.3d 731,
735–36 (7th Cir. 2003) (affirming sentence based on drug quantity calcula‐
tion in which more than ninety‐nine percent was based on relevant con‐
duct and citing similar cases). He does not press in this court the argu‐
ment, made in the district court, that his is “one of those rare instances” in
which a standard of proof higher than preponderance is appropriate be‐
cause of the “dramatic increase” in guidelines calculations caused by the
relevant conduct. Cf. id. at 736. In any event, given the strength of the evi‐
dence here, this argument is without merit.
11 Notably, at an earlier suppression hearing, the district court found that
the statement was voluntarily given in a noncoercive environment and
No. 14‐3787 13
reliable to form the basis for the district court’s drug quantity
findings.
A “defendant has a due process right to be sentenced on
the basis of reliable information,” United States v. Zehm, 217
F.3d 506, 514 (7th Cir. 2000), that is, on the basis of “infor‐
mation that has sufficient indicia of reliability to support its
probable accuracy,” United States v. Smith, 674 F.3d 722, 732
(7th Cir. 2012) (internal quotation marks omitted); see also
United States v. Johnson, 489 F.3d 794, 798 (7th Cir. 2007). Nev‐
ertheless, the Government’s burden at sentencing is substan‐
tially lower than at trial: the court is not limited to the evi‐
dence in support of the conviction and proved at trial or ad‐
mitted in the plea; instead, the court must only find that a
“preponderance of reliable evidence supports the drug quan‐
tity finding.” Cooper, 767 F.3d at 731. We review the sentenc‐
ing court’s determination of reliability for an abuse of discre‐
tion. See United States v. Mays, 593 F.3d 603, 608 (7th Cir. 2010).
We review the ultimate factual finding of the district court as
to the quantity of drugs attributable to a defendant for clear
error. United States v. Block, 705 F.3d 755, 759 (7th Cir. 2013).
In support of his argument that his statement is unreliable,
and therefore cannot form the basis for the ultimate drug
quantity finding, Mr. Tankson relies largely on United States
v. Robinson, 164 F.3d 1068 (7th Cir. 1999), and United States v.
Morrison, 207 F.3d 962 (7th Cir. 2000). But these cases are of no
assistance to Mr. Tankson. His statement cannot be character‐
had credited the statement and Agent Yoder’s testimony in support of it.
See R.113 at 157–58; R.157 at 77. The court also had concluded that
Mr. Tankson’s later testimony regarding the statement was false. See R.113
at 156–57.
14 No. 14‐3787
ized as “patently unreliable.” Morrison, 207 F.3d at 968 (char‐
acterizing a statement given in Robinson). More fundamen‐
tally, the statement at issue here is Mr. Tankson’s own state‐
ment. By contrast, the statements in Morrison were drug‐ad‐
dict statements, utterances that “courts should carefully scru‐
tinize.” Id. at 968.
In Robinson, we reviewed a sentence based on the massive
drug quantities derived from a single witness’s statement.
Although included in the PSR, this statement was untested by
cross‐examination and was not independently evaluated by
the district court for credibility. We acknowledged that the
district court was not required to hear from the witness, but
stated that it was “not a terribly bad idea” when the statement
was the support for such a significant proportion of the quan‐
tity. Robinson, 164 F.3d at 1070. More importantly, however,
we noted that there were problems with the particular state‐
ment in Robinson that made it incredible on its face and that,
consequently, the district court should have realized that it
was necessary to scrutinize its reliability before allowing it to
form the basis of the sentence. By contrast, in Morrison, we
upheld a sentence where statements included in the PSR in‐
creased the defendant’s drug quantity one hundredfold. 207
F.3d at 968–69. Although these statements came from several
witnesses, who were drug addicts, the statements sufficiently
corroborated one another and were each internally consistent.
In these cases, as in others, we have said that a district
court should exercise caution when the Government seeks a
long sentence on the basis of relevant conduct significantly
greater than the charged offense. Several considerations lead
us to believe that the district court exercised the requisite cau‐
No. 14‐3787 15
tion. First, Mr. Tankson’s claim is much more akin to the ob‐
jections that we reviewed in United States v. Johnson, 342 F.3d
731 (7th Cir. 2003). There, as here, the defendant challenged
the reliability of his own post‐arrest statement on drug quan‐
tity. In rejecting that challenge, we stated:
Self‐incriminating statements such as Johnson’s,
which was clearly against his penal interest,
“have long been considered reliable enough for
use at trial …, so we cannot say that they are too
unreliable for use at sentencing.” United States v.
Szakacs, 212 F.3d 344, 352—53 (7th Cir. 2000). In‐
deed, we have held that a drug dealer’s self‐in‐
criminating statement to a drug enforcement
agent, which was offered at sentencing solely
through the testimony of the agent (as opposed
to a written confession or testimony by the
dealer), was sufficiently reliable because “[n]o
one was more qualified than [the dealer] him‐
self to put a number on the amounts of cocaine
he was purchasing and re‐selling.” United States
v. Contreras, 249 F.3d 595, 602 (7th Cir. 2001).
Johnson, 342 F.3d at 734 (alterations in original). Moreover, we
cannot accept Mr. Tankson’s suggestion that the statement is
not sufficiently corroborated because the Government did not
identify any “enormous caches of money.”12 He points out
that the quantity he attributed to himself, at the prices he
identified, would have resulted in several hundred thousand
dollars in profit. There was evidence in the record, however,
of many potentially tainted assets: vehicles, property, and a
12 Appellant’s Br. 18.
16 No. 14‐3787
$6,000 diamond‐studded watch. In addition, Mr. Tankson
supported twelve children and his parents. In any event, alt‐
hough evidence of an otherwise “unexplained, lavish life‐
style” may be admissible in a drug‐related prosecution, see
United States v. Smith, 308 F.3d 726, 737 (7th Cir. 2002), we
have not required the Government to make such a showing.
Mr. Tankson has not identified any statement of his that is
problematic or incredible on its face such that it should have
given investigators pause and provoked a more thorough
fact‐checking of his own admissions. He simply submits that
his statement was vague because although he recalled using
drop phones and dialing a Mexican country code, he could
not remember what numbers he had dialed. Although a state‐
ment’s level of detail can bolster or reduce its reliability, see
Johnson, 489 F.3d at 798, we cannot say that his statement was
so lacking in detail as to be unreliable. It explains with suffi‐
cient specificity how Mr. Tankson developed his contacts and
carried out his trafficking activities.
Mr. Tankson also asserts that that the Government pro‐
duced no corroborating evidence of any of the additional, un‐
charged drug quantities, did not identify a single other cus‐
tomer, and did not attempt to corroborate his statements by
visiting either the auto repair shop where he met his suppliers
or the mall where he made his purchases. We already have
rejected the general argument that the Government is re‐
quired to corroborate a defendant’s own statements in order
to use them as the basis of a drug quantity calculation.13
13 See United States v. Contreras, 249 F.3d 595, 602 (7th Cir. 2001) (specifi‐
cally noting that there was “no independent evidence corroborating [the
defendant’s] post‐arrest statement” and concluding that the court was still
No. 14‐3787 17
Mr. Tankson’s statement presents no occasion for an excep‐
tion to that general rule. Indeed, Mr. Tankson’s statement has
been corroborated in important material respects. He was ar‐
rested on the basis of a sting operation, and his admissions
match the facts as known to the officers. Although his state‐
ment extends well beyond those facts to other trafficking be‐
havior, that additional behavior was consistent with the ob‐
served and known transactions. Finally, the statement was
given voluntarily to the authorities.14 Nothing in the record
suggests a plausible reason why Mr. Tankson would have in‐
flated his involvement in drug trafficking in his confession.
The district court, therefore, did not abuse its discretion when
it took Mr. Tankson’s statement at face value. Consequently,
its quantity calculation based on that statement certainly is
not clear error.
B.
Mr. Tankson next contends that, even if the drug quanti‐
ties are established sufficiently by his statement, the sales at‐
tributed to those quantities do not qualify as “relevant con‐
duct” under the guideline. The district court’s application of
the guidelines provision concerning relevant conduct to the
uncharged drug quantities is a factual issue that we review
for clear error. United States v. Delatorre, 406 F.3d 863, 866 (7th
“not preclude[d] … from relying on it”). “The requirement of reliable evi‐
dence … is a limitation on the court’s consideration of hearsay and other
‘evidence with uncertain provenance.’” United States v. Smith, 674 F.3d 722,
732 (7th Cir. 2012) (emphasis added).
14 See R.113 at 158 (hearing on Mr. Tankson’s motion to suppress); R.157
at 77.
18 No. 14‐3787
Cir. 2005).
The governing principles are well established. The rele‐
vant conduct guideline requires the sentencing court to aggre‐
gate, in calculating a base offense level, “all acts and omis‐
sions committed, aided, abetted, counseled, commanded, in‐
duced, procured, or willfully caused by the defendant” “that
were part of the same course of conduct or common scheme
or plan as the offense of conviction.” U.S.S.G. § 1B1.3(a)(1)(A),
(a)(2). As we have explained,
[i]n United States v. Duarte, we noted that this
“relevant conduct” or “aggregation rule”
“grants the government a fearsome tool in drug
cases. It permits prosecutors to ‘indict defend‐
ants on relatively minor offenses and then seek
enhanced sentences later by asserting that the
defendant has committed other more serious
crimes for which, for whatever reason, the de‐
fendant was not prosecuted and has not been
convicted.’” 950 F.2d 1255, 1263 (7th Cir. 1991).
However, the relevant conduct rule has limits.
The rule allows sentencing courts to consider
quantities of drugs not specified in the counts of
conviction, provided “the unconvicted activi‐

United States v. Ortiz, 431 F.3d 1035, 1040 (7th Cir. 2005). In
determining whether additional drug quantities are relevant,

as to warrant the conclusion that they are part

of a single episode, spree, or ongoing series of
offenses.” In making this determination, the
court may look to the “similarity of the offenses,
the regularity (repetitions) of the offenses, and
the interval between the offenses.”

(9) “Common scheme or plan” and “same course of con‐
duct” are two closely related concepts.
(A) Common scheme or plan. For two or more
offenses to constitute part of a common scheme
or plan, they must be substantially connected to
each other by at least one common factor, such as
common victims, common accomplices, common
purpose, or similar modus operandi. For example,
the conduct of five defendants who together de‐
frauded a group of investors by computer ma‐
nipulations that unlawfully transferred funds
over an eighteen‐month period would qualify
as a common scheme or plan on the basis of any
of the above listed factors; i.e., the commonality
of victims (the same investors were defrauded
on an ongoing basis), commonality of offenders
(the conduct constituted an ongoing conspir‐
acy), commonality of purpose (to defraud the
group of investors), or similarity of modus op‐
erandi (the same or similar computer manipu‐
lations were used to execute the scheme).
(B) Same course of conduct. Offenses that do
not qualify as part of a common scheme or plan
may nonetheless qualify as part of the same
course of conduct if they are sufficiently connected

decision to count all amounts that comprise a “continuous
pattern of drug trafficking,” id. at 348. See, e.g., United States v.
Farmer, 543 F.3d 363, 373 (7th Cir. 2008) (“Where the defend‐
ant’s convicted offense was merely the latest drug sale in an
unbroken series of deals regularly made, that is sufficient to
find the defendant’s prior drug transactions were part of the
same course of conduct as the offense of conviction.”).
Now that the governing principles have been set forth, we
review precisely what Mr. Tankson’s statement says about his
or related to each other as to warrant the conclusion
that they are part of a single episode, spree, or ongo‐
ing series of offenses. Factors that are appropriate
to the determination of whether offenses are
sufficiently connected or related to each other
to be considered as part of the same course of
conduct include the degree of similarity of the of‐
fenses, the regularity (repetitions) of the offenses,
and the time interval between the offenses. When
one of the above factors is absent, a stronger
presence of at least one of the other factors is re‐
quired. For example, where the conduct alleged
to be relevant is relatively remote to the offense
of conviction, a stronger showing of similarity
or regularity is necessary to compensate for the
absence of temporal proximity. The nature of
the offenses may also be a relevant considera‐
tion (e.g., a defendant’s failure to file tax returns
in three consecutive years appropriately would
be considered as part of the same course of con‐
duct because such returns are only required at
yearly intervals).

trafficking activity. He stated that he met his first heroin sup‐
plier “about two years ago.”16 He then stated that he sold ma‐
rijuana “[f]or a few months” until this supplier trusted him,
and then began selling heroin.17 After the first supplier was
robbed, he was introduced to a second supplier. He described
their transactions as occurring over prepaid drop phones; he
called the supplier whenever he needed heroin, ordering only
as much as he could sell on a given day. During the call, he
received an instruction on the place to meet couriers (usually
the Ford City Mall). The report of his statement continues:
Over the last two years, TANKSON estimated
that he placed approximately 100 heroin orders
from Mexican 2. TANKSON estimated that each
of the 100 heroin orders was for approximately
300 grams to 400 grams of heroin. Mexican 2
charged $6,500 per 100 grams of heroin and
TANKSON sold the heroin for $8,000 per 100
grams. … Mexican 2 changed his couriers often.
The transactions with the couriers took place
from their vehicles in the parking lot, window‐
to‐window from TANKSON’s car to the cou‐
rier[’]s car. TANKSON provided money and
picked up the heroin during the same transac‐
tion. TANKSON remembered Mexican 2 telling
him that he needed to change vehicles and
phones often to avoid law enforcement detec‐
tion, specifically wire taps and tracking devices.
TANKSON ceased selling heroin following

a law enforcement encounter when police
seized approximately $3,500.00 [Aforemen‐
tioned TIII recordings surrounding 01/03/2013
transaction.] of narcotics proceeds from
TANKSON …, because TANKSON thought the
police were on to his narcotics sales.[18]
The district court found that the statement established that
these transactions involved the same drug that he sold to
Blackman during the same timeframe. As the Government
notes, the statement also establishes a common accomplice
(the second supplier), a common modus operandi (the way
orders were placed, the size of the orders, the manner of
pickups, and the pricing), and a common purpose of a large‐
quantity, high‐turnover trafficking operation. Although
Mr. Tankson now claims that we do not know when the 100
transactions with the second supplier took place, the only rea‐
sonable reading of his statement is that they took place with
some regularity from the time he met the supplier until he
stopped dealing after his encounter with law enforcement.
The suggestion in his appellate brief that he may have had 100
separate transactions with the suppliers at the beginning of
the two years on 100 consecutive days is an implausible read‐
ing of his statement. Moreover, even if it did represent a per‐
missible view of the evidence, it would not justify reversal,
especially under the clear error standard. See Block, 705 F.3d
at 759–60; United States v. Marty, 450 F.3d 687, 690 (7th Cir.
2006).

patterns. See, e.g., Ortiz, 431 F.3d at 1041–42 (finding no rele‐
vant conduct when there was a ten‐month gap between
charged conduct and relevant conduct and where the offenses
were not sufficiently similar because they involved different
drugs, a smaller scale operation, and significantly smaller
drug quantities).19 This case presents no such situation. The
evidence before the district court certainly justified the con‐
clusion that Mr. Tankson had engaged in a continuous pattern
of reselling drugs that he had acquired from the second sup‐
19 See also United States v. Purham, 754 F.3d 411, 414–15 (7th Cir. 2014) (find‐
ing two transactions, two years apart, lacking in common accomplices and
modus operandi, were not sufficiently related for relevant conduct pur‐
poses, even though they involved delivery of same drug to same town);
United States v. Bacallao, 149 F.3d 717, 721 (7th Cir. 1998) (“[T]he PSI estab‐
lishes only one common element between the charged offense and the
one‐kilogram transaction: the relationship between Saunders and
Bacallao. This link is not enough, standing alone, to show that the trans‐
action was part of the same course of conduct or common scheme or plan
as the offense of conviction. The record contains no evidence establishing,
for instance, relevant dates, common victims, or details concerning the
manner in which the kilogram of cocaine was acquired and distributed.”).
Nevertheless, we have not hesitated to count quantities when the neces‐
sary links exist. See, e.g., United States v. Vaughn, 722 F.3d 918, 932 (7th Cir.),
cert. denied, 134 S. Ct. 541 (2013) (“When a substantial period of time exists
between drug offenses without any intervening activity, it is possible to
conclude that the defendant put his criminal activity on hold during that
period of time. But where a defendant sells drugs, albeit to different pur‐
chasers, for an extended period of time with little or no break leading up
to the charged offense, it is much more likely that the sales are part of the
same common scheme or plan as the offense of conviction.”); United States
v. Crockett, 82 F.3d 722, 730 (7th Cir. 1996) (finding links established a com‐
mon scheme or plan when there was a common accomplice, a common
purpose to sell cocaine, and a common modus operandi of meeting in a
restaurant and proceeding to another location to transfer drugs).

plier to individuals including Blackman. The relevant con‐
duct determination is not clearly erroneous.
C.
Finally, Mr. Tankson challenges the district court’s deci‐
sion to apply the career offender enhancement of Guideline
§ 4B1.1(a). After calculating Mr. Tankson’s base offense level,
the district court, accepting the view in the PSR, determined
that Mr. Tankson qualified as a career offender. We review
the application of the guideline de novo. United States v. Kin‐
dle, 453 F.3d 438, 440 (7th Cir. 2006).
To attain career offender status under the guidelines a de‐
fendant must be eighteen years or older at the time of the pre‐
sent offense; that offense must be for a crime of violence or for
a controlled substance offense, and the defendant must have
two prior felony convictions of either a crime of violence or of
a controlled substance offense. See U.S.S.G. § 4B1.1(a). Only
prior felony convictions resulting in a term of imprisonment
exceeding one year and one month may be counted. Moreo‐
ver, the person’s sentence must have been imposed within 15
years of the “commencement of the instant offense,” or have
resulted in the defendant being incarcerated during any part
of the same 15 year period. Id. § 4A1.2(e)(1). According to ap‐
plication note 8 to § 4A1.2, “the term ‘commencement of the
instant offense’ includes any relevant conduct.” The PSR and
the district court counted a 1995 offense for which Mr. Tank‐
son was paroled in July 1997 because the relevant conduct for
the present offense stretched back to January 2011. As
No. 14‐3787 25
Mr. Tankson noted both here and before the district court,20
this argument is entirely dependent on the court’s conclu‐
sions with respect to relevant conduct. Because we have con‐
cluded that the district court did not clearly err in its relevant
conduct determination, this argument is also without merit.21
Conclusion
The district court did not abuse its discretion in determin‐
ing that Mr. Tankson’s voluntary post‐arrest statement to the
authorities was sufficiently reliable to establish the significant
drug quantities attributed to Mr. Tankson at sentencing. Nor
did the court clearly err in determining, on the facts before it,
that those quantities fit within the relevant conduct guideline.
Our determination that there was no reversible error on the
relevant conduct issue necessarily forecloses an argument on
the career offender enhancement. Accordingly, there was no
error in the adjudication of Mr. Tankson’s sentence. The judg‐
ment of the district court is affirmed.
AFFIRMED

21 Moreover, as the district court noted, even without the increase to a
criminal history category of VI, the applicable guidelines range for an of‐
fense level of 38 at criminal history category V would still have been 360
months to life. See R.157 at 88.
