Before: GIBBONS and KETHLEDGE, Circuit Judges; DOW, District Judge.

DOW, District Judge. Defendant Sangchaenh Sengmany pled guilty to an indictment 

charging him with (1) conspiracy to distribute and possess with intent to distribute 50 grams or 

more of methamphetamine and (2) being a felon in possession of a firearm. At sentencing, 

Sengmany contested the amount of drugs attributed to him for purposes of the Sentencing 

Guidelines, objected to an enhancement of his offense level for possession of firearms in 

connection with the offense, argued that he should not receive an enhancement for his role in the 

offense, and maintained that he should receive a reduction in his offense level for acceptance of 

responsibility. The district judge overruled all of Sengmany’s objections to the guideline

calculations, calculated an offense level of 42 and a criminal history category of IV, and 

concluded that the factors set out in 18 U.S.C. § 3553(a) and the arguments advanced by counsel 

in mitigation did not merit a significant reduction from the advisory guideline range. Although

her rulings resulted in a guideline range of 360 months to life, the district judge imposed a 

sentence of 240 months. Sengmany now appeals his sentence, raising essentially the same 

arguments that he raised before the district judge. For the reasons set forth below, we affirm.

I.

In November 2012, a federal grand jury returned a seven-count indictment charging 

Sangchaenh Sengmany, a citizen of Laos who was living in Holland, Michigan, and three coconspirators, Amber and Amanda Dordon and Phetmany Choummanivong, with 

methamphetamine and gun-related offenses. Sengmany entered a plea of guilty to two counts—

conspiracy to distribute and possess with intent to distribute 50 grams or more of 

methamphetamine (count one) and felon in possession of a firearm (count four)—in exchange 

for dismissal of the other counts. During his change of plea hearing, Sengmany told the 

magistrate judge that he received “three to four” packages of methamphetamine in the mail, each 

containing an ounce of the drug, for which he paid $1,000 or $1,500. He admitted that he sold a 

ball of methamphetamine (three grams) to Amber Dordon “[t]hree times a month,” “one gram” 

once to Amanda, and a gram “three to four times” to Choummanivong. He also acknowledged

using the three firearms found at his residence for hunting, although he claimed that the guns 

belonged to his wife. In accepting his plea, the magistrate judge expressed frustration, 

commenting that Sengmany appeared to be “not coming clean with the Court.” 

After Sengmany entered into a written plea agreement with the government, the United 

States Probation Department prepared a presentence report (“PSR”). The factual information in 

the report was taken largely from law enforcement reports of witness interviews as well as grand 

jury testimony. The report found Sengmany responsible for 809.4 grams (29 ounces) of 

methamphetamine: 27.2 grams recovered via an intercepted U.S. Mail package from California 
3

delivered to one of Sengmany’s residences on December 1, 2011; 113.4 grams that he provided 

to Vilay Keodouangdy, a former “runner” for Sengmany; 57 grams that he provided in 2005-06 

to Claire Parks, a woman whom investigators had interviewed; and 640 grams that he provided 

to Amber and Amanda Dordon between June 1 and December 1, 2011. Based on that total drug 

quantity, the report assigned a base offense level of 36, which applies to crimes involving at least 

500 grams, but less than 1.5 kilograms, of “ice” methamphetamine.1 The report also assessed a 

two-level enhancement for possessing a dangerous weapon, citing Vilay Keodouangdy’s grand 

jury testimony that Sengmany gave him a rifle to protect himself and the drugs, as well as a fourlevel leadership enhancement. Finally, the report recommended denying Sengmany a three-level 

reduction for acceptance of responsibility, stating that he failed to acknowledge his full 

involvement in the offense, including the number of drug packages sent to his residence, his 

relationship with Amber Dordon and the quantity of methamphetamine that he sold to her, and 

the fact that he had provided Keodouangdy with a firearm and ammunition in connection with

their drug trafficking.

The PSR also set forth Sengmany’s criminal history, which included convictions for 

aggravated burglary, drunk driving and driving without a license (multiple times), illegal entry, 

felon in possession, and felonious assault on his then-girlfriend, who later became his wife.

2

 The 

PSR provided a guideline range of 360 months to life based on a total offense level of 42 and a 

criminal-history category of IV.

 

1

 The intercepted package contained methamphetamine with a purity of 98.3%, which qualified 

it as “ice.” 

2

 In regard to the assault conviction, the report stated that the victim’s right eye and lips were 

swollen, that she had blood on her face, that Sengmany had kicked the victim several times in the 

stomach, and that officers had found a .22 caliber rifle with a round in the chamber on the 

kitchen floor. At the time of the offense, Sengmany was arrested and determined to have a blood 

alcohol content of .16%. After his arrest, the victim told police that Sengmany had threatened 

her with a knife and pointed the gun at her head saying he was going to kill her. 
4

Prior to sentencing, Sengmany filed a pro se motion to withdraw his guilty plea, claiming 

that he did not understand the plea agreement, that his attorney had not explained it to him, and 

that his attorney had pressured him into signing it. After a hearing, the district court denied 

Sengmany’s motion, finding that he was not maintaining his innocence and that his motion 

reflected “buyer’s remorse,” but “nothing * * * to support the defendant’s claim that he was 

somehow intimidated into signing the plea agreement.” 

At sentencing, Sengmany contested the amount of drugs attributed to him and the 

enhancements for possession of firearms in connection with the offense and for his role in the 

offense. He also argued that he should receive a deduction from his offense level for acceptance 

of responsibility. After considering the PSR, sentencing memoranda, the arguments of counsel, 

and hearing testimony from Sengmany, as well as from a postal inspector about the drugs 

delivered to two residences at which Sengmany lived, the district court overruled all of 

Sengmany’s objections to the guideline range set out in the PSR and determined that the range 

was 360 months to life. 

Regarding drug quantity, the district court stated that it was difficult to find “any 

credibility” in Sengmany’s testimony that “he got on five occasions one ounce of the drug, 

smoked half of it, and gave away or sold to these others the other three, the remainder of these 

drugs, and that’s all there was.” The district court acknowledged that Sengmany used the drugs 

for personal consumption, but also noted that he was “responsible for doling them out for 

distribution and sale.” The court highlighted the postal inspector’s testimony about 17 

suspicious packages delivered from California (of similar weight and size to a package of 

approximately one ounce of methamphetamine intercepted by postal inspectors in December 

2011) to two addresses where Sengmany lived or admitted receiving packages. The court further 
5

noted that it did not find credible Sengmany’s testimony that he did not know about all of the 

deliveries. Finally, the court pointed to testimony by the Dordon sisters and Vilay Keodouangdy

that Sengmany regularly supplied them with drugs.

The district court also found that the government had met its burden of showing that 

Sengmany possessed a firearm during his drug-trafficking offense. The court referenced 

Sengmany’s attempts to distance himself from the firearms—they were for hunting or they were 

his wife’s—but concluded that Vilay Keodouangdy’s testimony that Sengmany provided him 

with use of a gun for protection of himself and the drugs was more credible than Sengmany’s. In 

addition, the district court denied Sengmany credit for acceptance of responsibility, finding that 

he had “persistently attempted to minimize his role.” The court noted that “it was a little bit like 

pulling teeth” for him to admit the actual basis for his guilty plea in the first instance and then 

noted that his “reluctance, unwillingness, [and] sense of denial” had continued through the 

proceedings. 

After ruling on Sengmany’s objections, the district court considered the § 3553(a) factors, 

and noted that many—his abandonment of his wife and children, his extensive criminal history, 

and his lack of cooperation—did not reflect favorably on him. Although the court concluded that 

the § 3553(a) factors and defense arguments did not warrant a significant reduction from the 

guideline range, in considering what sentence would be sufficient but not greater than necessary 

to achieve the goals of sentencing, the court concluded that 360 months to life was “a bit beyond 

the pale” and imposed a sentence of 240 months, 120 months below the low end of the range.

II

Sengmany raises four issues on appeal. First, he contends that the evidence was not 

sufficient to support the district court’s finding that he was responsible for more than 500 grams 
6

of methamphetamine. Second, he contends that the district court erred when it assessed a twolevel enhancement for Sengmany’s possession of a firearm during the conspiracy and declined to 

reduce his offense level to reflect acceptance of responsibility. Finally, he argues that the 240-

month sentence was unreasonable because the district court incorrectly calculated the guideline 

range. As set forth below, because we conclude that Sengmany’s first three arguments fail to 

demonstrate clear error by the sentencing judge, we need not reach his final argument that the

alleged errors resulted in an inflated guideline range.

A.

In order to determine the base offense level for sentencing purposes, the district court 

must determine the quantity of drugs for which a defendant is responsible. Sengmany contends 

that the district court erred in concluding that he was responsible for distributing at least 500 

grams of methamphetamine “ice,” which resulted in assignment of a base offense level of 36. 

We review the district court’s factual finding as to the amount of methamphetamine attributable 

to Sengmany for clear error. United States v. Samuels, 308 F.3d 662, 670 (6th Cir.

2002) (citing United States v. Jenkins, 4 F.3d 1338, 1345-46 (6th Cir. 1993)).

“A drug quantity need only be established by a preponderance of the evidence, and an estimate

will suffice so long as it errs on the side of caution and likely underestimates the quantity of 

drugs actually attributable to the defendant.” United States v. Anderson, 526 F.3d 319, 326 (6th 

Cir. 2008). Further, “a district court’s approximation of drug quantity is not clearly erroneous if 

it is supported by competent evidence in the record.” United States v. Jeross, 521 F.3d 562, 570 

(6th Cir. 2008). For instance, “testimonial evidence from a coconspirator may be sufficient to 

determine the amount of drugs for which another coconspirator should be held accountable.” 
7

United States v. Swanberg, 370 F.3d 622, 625 (6th Cir. 2004) (quoting United States v. 

Hernandez, 227 F.3d 686, 697 (6th Cir. 2000)). 

The evidence in the record, much of it discussed in detail in the PSR (which the district

court adopted) and referenced by the court at sentencing, supports a finding that Sengmany was 

responsible for at least 500 grams of methamphetamine. The district court, relying partially on 

coconspirator testimony as well as testimony from the postal inspector, discussed the 17 

suspicious packages delivered to Sengmany’s two residences, each containing at least one ounce

of methamphetamine. Although Sengmany points out that 17 one-ounce (28 gram) packages 

total 476 grams—less than the 500-gram threshold for base offense level 36—the record reflects 

that Vilay Keodouangdy told law enforcement that Sengmany often paid $3,000 for two ounces 

at a time. There also was evidence indicating that Sengmany and his coconspirators occasionally 

obtained methamphetamine from other sources. Finally, the amounts that Sengmany supplied to 

Amanda and Amber Dordon alone crossed the 500-gram threshold.3 See United States v. Porter, 

560 Fed. App’x 543, 545 (6th Cir. 2014) (observing that “time and again” this Court has held 

that “[t]estimonial evidence from a coconspirator may be sufficient to determine the amount of 

drugs for which another coconspirator should be held accountable”) (quoting Swanberg, 370 

F.3d at 625); see also United States v. Cohen, 515 Fed. App’x 405, 412-13 (6th Cir. 2013) 

(noting that district court may base its fact-finding on the prior statements of conspirators “so 

 

3

 The PSR attributed 640 grams to Sengmany based on his transactions with the Dordon sisters. 

Amanda claimed that she and Amber operated an “every day, all day operation” in which 

Sengmany supplied them at least 3.5 grams of methamphetamine daily, which they broke down 

into smaller portions and sold. As the government pointed out in its sentencing memorandum, 

even using the lower amount of 1.8 grams per day for June and July 2011 that Amber Dordon 

admitted to, and the 3.5 grams per day figure for August 1 to December 1, 2011, that Amber 

confirmed, the amount was at least 528 grams. Thus, any error in the court’s decision to adopt 

the 640 grams quantity rather than the 528-grams quantity proposed by the government was 

harmless given the 500-grams threshold. See, e.g., United States v. Lanesky, 494 F.3d 558, 561 

(6th Cir. 2007) (alleged sentencing error is harmless if it did not cause the defendant to receive a 

more severe sentence).
8

long as ‘it is not obvious that the statements were untruthful’”) (quoting United States v. Milan, 

398 F.3d 445, 457 (6th Cir. 2005)). 

Sengmany also claims the district court erred in failing to consider his personal drug use,

and thus the court inflated the amount of drugs he intended to or did distribute. While the court 

noted Sengmany’s personal use, it highlighted the amounts set forth in the PSR, which accounted 

for over well over 500 grams. The court then referenced “the mountain . . . of evidence of the

others,” concluding that it could not be reconciled with Sengmany’s testimony as to how much 

methamphetamine he kept for personal use. Indeed, the statements and testimony in the PSR 

from the Dordon sisters, Vilay Keodouangdy, and Claire Parks about the quantities that they 

received from Sengmany, as well as corroborating evidence of packages delivered to 

Sengmany’s residences, support the conclusion that the district judge reached—namely, that 

Sengmany was responsible for “a great deal more of the methamphetamine than he [was] willing 

to acknowledge.” We accord “great deference to such credibility determinations,” United States 

v. Navarro–Camacho, 186 F.3d 701, 705 (6th Cir. 1999), because the district court is “in 

the best position to judge credibility,” United States v. Bradshaw, 102 F.3d 204, 210 (6th Cir.

1996) (finding it not clearly erroneous for the district court to credit testimony and articulate, on 

its own, plausible explanations for apparent inconsistencies). As the district court reasoned, the 

other evidence could not be reconciled with Sengmany’s statements as to personal use, and her 

decision to credit that evidence over Sengmany’s testimony was not clearly erroneous. See

United States v. Gauna, 485 Fed. Appx. 70, 74-75 (6th Cir. 2012). 

Sengmany’s strongest argument is that the district court was not permitted to rely on 

Claire Parks’ grand-jury testimony, given that Parks’ testimony referenced transactions that 

occurred in 2005-06, well before the indictment in this case. See, e.g., United States v. Hill, 79 
9

F.3d 1477 (6th Cir. 1996) (remote and dissimilar drug sales will not qualify as relevant conduct). 

Although the district judge did not reference Parks’ testimony during sentencing, it was part of 

the PSR calculation and thus she implicitly must have included it in adopting the PSR figures. 

But even if the district court counted the 57 grams that Sengmany allegedly provided to Parks in 

her estimate, as set forth above, the quantities that Sengmany supplied the Dordon sisters alone 

cross the 500-gram threshold for base offense level 36, so any error in relying on the transactions 

with Parks (if in fact the district court did so) was harmless. See, e.g., Lanesky, 494 F.3d at 561 

(alleged sentencing error is harmless if it did not cause the defendant to receive a more severe 

sentence).

In short, Sengmany asks the Court to believe his version of the events—in which he 

denies receiving many of the packages from California and supplying his coconspirators with the 

quantities that they attested to—over the testimony and statements of his coconspirators and 

other witnesses. Where two permissible views of the evidence exist, and where the testimony of 

Defendant’s coconspirators was corroborated by evidence of actual drug deliveries to 

Sengmany’s residence of anywhere from 17 to 34 ounces of methamphetamine, we cannot find 

clear error in the district court’s decision to discredit Sengmany’s version of the events. See 

Anderson v. City of Bessemer, 470 U.S. 564, 573-74 (1985) (“Where there are two permissible 

views of the evidence, the factfinder’s choice between them cannot be clearly erroneous.”); 

Jeross, 521 F.3d at 570 (credibility determinations accorded great deference). 

B.

Sengmany next contends that the district court erred when it assessed a two-level 

enhancement for possession of a firearm during the drug conspiracy. As with the district court’s 

finding as to drug quantity, a finding that a defendant possessed a firearm during a drug crime is 
10

a factual finding reviewed for clear error. United States v. Darwich, 337 F.3d 645, 664 (6th Cir. 

2003).

The Sentencing Guidelines call for a district court to apply a two-level increase if the 

defendant possessed “a dangerous weapon (including a firearm).” U.S.S.G. § 2D1.1(b)(1). 

Application note 11 to § 2D1.1 provides in relevant part: “The enhancement for weapon 

possession in subsection (b)(1) reflects the increased danger of violence when drug traffickers 

possess weapons. The enhancement should be applied if the weapon was present, unless it is 

clearly improbable that the weapon was connected with the offense.”

To apply the § 2D1.1(b)(1) enhancement, the government has the initial burden of 

showing by a preponderance of the evidence that (1) the defendant actually or constructively 

possessed the weapon, and (2) such possession was during the commission of the offense, or 

during “relevant conduct.” United States v. Greeno, 679 F.3d 510, 514 (6th Cir. 2012); United 

States v. Faison, 339 F.3d 518, 520 (6th Cir. 2003). “‘Constructive possession of an item is the 

ownership, or dominion or control over the item itself, or dominion over the premises where the 

item is located.’” United States v. Wheaton, 517 F.3d 350, 367 (6th Cir. 2008) (emphasis in 

original) (quoting United States v. Hill, 79 F.3d 1477, 1485 (6th Cir. 1996) (citation and internal 

quotation marks omitted)). “Relevant conduct” includes “‘all acts and omissions . . . that were 

part of the same course of conduct or common scheme or plan as the offense of 

conviction.’” Faison, 339 F.3d at 520 (quoting U.S.S.G. § 1B1.3(a)(2)). Once the government 

meets its burden, a rebuttable presumption arises that the weapon was connected to the 

offense. Greeno, 679 F.3d at 514. The burden then shifts to the defendant to show that it was 

“clearly improbable” that the weapon was connected to the offense. Id.
11

Sengmany admitted through his guilty plea that he unlawfully possessed three firearms 

found at one of his residences (the Lot 102 residence) in or around December 2011 (while the 

conspiracy was ongoing), including two .22 caliber rifles. Thus, a presumption arose that the 

enhancement applied and the burden shifted to Sengmany to demonstrate that it was clearly 

improbable that the firearms were connected to his drug crimes. Sengmany argues that he 

rebutted the presumption because he was not living at the Lot 102 residence where the guns were 

found. But he was living at the 136th Avenue residence, where the .22 caliber ammunition 

matching one of the rifles was found. And, even by his own admission, he was receiving 

methamphetamine at the Lot 102 residence. 

Sengmany argues that he has carried his burden because he testified that he used the guns 

for hunting. But the district court found that Sengmany’s testimony was not credible. We have 

no reason to second-guess that determination, so that argument fails. It was not clear error for 

the district court to discredit Sengmany’s story and to conclude that he therefore did not rebut the 

presumption. 

C.

In his final specific challenge, Sengmany contends that the district judge erred in 

declining to reduce his offense level to reflect acceptance of responsibility. Because the district 

court “is in a unique position to evaluate a defendant’s acceptance of responsibility . . . the 

determination of the [court] is entitled to great deference on review.” U.S.S.G. § 3E1.1 cmt. n.5. 

Therefore, we again review for clear error, see United States v. Genschow, 645 F.3d 803, 813 

(6th Cir. 2011), and the district court’s determination “will not be overturned unless it is without 

foundation.” United States v. Morrison, 983 F.2d 730, 732 (6th Cir. 1993). 
12

Section 3E1.1(a) of the guidelines provides for a two-level decrease in a defendant’s

offense level “[i]f the defendant clearly demonstrates acceptance of responsibility for his 

offense[.]” In determining whether a defendant has accepted responsibility, the district court 

may consider whether the defendant truthfully admits, or does not falsely deny, “any additional 

relevant conduct for which the defendant is accountable under § 1B1.3 (Relevant 

Conduct).” U.S.S.G. § 3E1.1, cmt. (n.1(A)). Although “a defendant is not required to volunteer, 

or affirmatively admit, relevant conduct beyond the offense of conviction in order to obtain a 

reduction . . . a defendant who falsely denies, or frivolously contests, relevant conduct that the 

court determines to be true has acted in a manner inconsistent 

with acceptance of responsibility.” Id.; see also United States v. Chalkias, 971 F.2d 1206, 1216 

(6th Cir. 1992) (defendants’ efforts to minimize their roles in drug conspiracy justify denial of 

reduction for acceptance of responsibility); United States v. Reeves, 100 Fed. App’x 470, 471 

(6th Cir. 2004) (noting that a “defendant’s attempt to minimize his own role in the offense is 

inconsistent with acceptance of responsibility”) (citing United States v. Edwards, 272 F.3d 812, 

816 (6th Cir. 2001)).

The district court did not clearly err in determining that Sengmany did not accept 

responsibility and therefore was not entitled to a reduction in his offense level on that basis. 

There was ample evidence in the transcript of the plea proceeding, in the PSR, and at the 

sentencing hearing to show that Sengmany had not accepted responsibility and had instead tried 

to minimize his role in the conspiracy. See Genschow, 645 F.3d at 813. The PSR recommended 

denying Sengmany a reduction for acceptance of responsibility, stating that he failed to 

acknowledge his full involvement in the offense, including the number of drug packages sent to 

his residence, his relationship with Amber Dordon and the quantity of methamphetamine that he 
13

sold to her, and the fact that he had provided Keodouangdy with a firearm and ammunition in 

connection with their drug trafficking. At the sentencing hearing, he continued his pattern of 

minimization, contending that he was only responsible for five packages of methamphetamine, 

plus the three that he claimed he allowed others to send to his residences. As previously set 

forth, the district court did not clearly err in finding that his testimony as to drug quantity and 

possession of firearms was not credible in light of other statements and testimony. By extension, 

the district court did not err in determining that Sengmany failed to earn credit for accepting 

responsibility when he continued to minimize his role in the conspiracy. 

III.

For the reasons stated above, the judgment of the district court is affirmed.
