(D.C. No. 1:11-CR-02868-LH-1)

(D.N.M.)

ORDER AND JUDGMENT*

Before LUCERO, GORSUCH, and HOLMES, Circuit Judges.

After a search of Maria Valdez-Perea’s (“Ms. Valdez’s”) person revealed a

package of heroin, she was indicted for possession with intent to distribute in

violation of 21 U.S.C. §§ 841(a)(1) and 841(b)(1)(A). Ms. Valdez filed a motion

to suppress the evidence, alleging that the search was conducted without her

voluntary consent and thus violated the Fourth Amendment. The district court

denied the motion. Ms. Valdez subsequently pleaded guilty and sought a minorrole adjustment to her sentence pursuant to § 3B1.2 of the United States

* This order and judgment is not binding precedent, except under the

doctrines of law of the case, res judicata, and collateral estoppel. It may be cited,

however, for its persuasive value consistent with Federal Rule of Appellate

Procedure 32.1 and Tenth Circuit Rule 32.1.

Sentencing Guidelines (“U.S.S.G.” or “Guidelines”). The district court denied the

adjustment. Ms. Valdez now appeals on two grounds: that she never voluntarily

consented to the search, and that the district court misapplied the Guidelines in

refusing her the minor-role adjustment. Exercising jurisdiction pursuant to 28

U.S.C. § 1291, we affirm. 

I

On October 23, 2011, Special Agent Jarrell Perry of the United States Drug

Enforcement Administration (“DEA”) and Agent Dena Willatto of the New

Mexico State Police conducted a plainclothes drug-interdiction operation at the

Greyhound bus station in Albuquerque, New Mexico.1

 The agents boarded a bus

headed east from Los Angeles that had pulled into the station, and they began to

speak with the passengers. Agent Perry encountered Ms. Valdez, who was seated

by a window near the rear of the bus, and, after establishing that she was a

Spanish speaker, spoke to her in Spanish—a language in which he is proficient

“enough to ask interdiction questions.” R., Vol. I, at 59 (Mem. Op. & Order,

filed May 21, 2012). He identified himself as a police officer and, in a

1 At the hearing on Ms. Valdez’s motion to suppress, the district court

found the testimony of Agents Perry and Willatto credible, whereas it found Ms.

Valdez’s testimony not credible. We “accept the district court’s findings of fact

and credibility determinations unless clearly erroneous,” United States v. Benard,

680 F.3d 1206, 1210 (10th Cir. 2012), and Ms. Valdez does not claim that the

district court committed clear error in its credibility determinations. Accordingly,

the facts relating to the incident at issue are drawn from the district court’s

factual findings.

Appellate Case: 13-2056 Document: 01019378505 Date Filed: 01/30/2015 Page: 2 
“conversational, cordial tone,” id. at 60, asked Ms. Valdez about her itinerary and

place of residence. He inquired whether he could see her ticket, to which she

assented. He then asked for her identification papers, and Ms. Valdez silently

handed them to him. Additionally, Ms. Valdez authorized a search of her purse

and blanket. The encounter then proceeded as follows:

Then [Agent Perry] asked, “May I search your person?” 

Although Defendant said nothing verbally, she nodded her head,

then stood up from her window seat, moved into the aisle, and

lifted her arms at a 90 degree angle from her body. Defendant

faced the front of the bus while Agent Perry was behind her, so

as not to block the pathway towards the door. Based on her

actions, Agent Perry believed Defendant was giving him consent

to search her person. Agent Perry started his pat-down search at

her waist in the stomach area and then patted down her back near

the waist area. He did not search Defendant’s breast or groin

areas. . . .

Agent Perry observed that Defendant had on a tight-fitting body

suit. He felt a hard bundle on Defendant’s left side near her

waist. Upon Agent Perry feeling the area with the bundle,

Defendant immediately turned away and sat down. 

Id.2

Agent Perry then asked Agent Willatto, who is female, whether she would

conduct a search of Ms. Valdez. Together, the agents returned to where Ms.

2 Ms. Valdez testified at the suppression hearing that she did not

consent to the search, that she made no gestures with her head to authorize the

search, and that Agent Perry touched her “private parts.” R., Vol. III, at 52–53

(Tr. Suppression Hr’g, dated May 1, 2011). Because the district court discounted

her testimony as non-credible, and because Ms. Valdez does not challenge that

ruling on appeal, we do not rely on Ms. Valdez’s account. See United States v.

Cash, 733 F.3d 1264, 1273 (10th Cir. 2013), cert. denied, --- U.S. ----, 134 S. Ct.

1569 (2014); Benard, 680 F.3d at 1210.

Appellate Case: 13-2056 Document: 01019378505 Date Filed: 01/30/2015 Page: 3 
Valdez was seated, and Agent Perry again asked for consent to search her person. 

Again, Ms. Valdez stood up, stepped into the aisle, and raised her arms. Agent

Willatto then searched her and discovered brown packaging tape—at which point

Ms. Valdez pushed Agent Willatto’s hand away. Ms. Valdez was then arrested

based on the agents’ “belie[f] [that] the hard objects [detected] were consistent

with others containing illegal narcotics.” Id. at 61. Subsequent testing revealed

that she had been concealing 1.1 kilograms of heroin under her clothing.

Ms. Valdez was ultimately indicted for possessing with intent to distribute

one kilogram or more of heroin in violation of 21 U.S.C. §§ 841(a)(1) and

841(b)(1)(A). She filed a motion to suppress all the evidence seized from her,

arguing that it was gathered in violation of her Fourth Amendment rights because

she never voluntarily consented to the search. After a hearing, the district court

denied Ms. Valdez’s motion to suppress, reasoning that Ms. Valdez demonstrated

consent by standing, stepping into the aisle, raising her arms, and nodding. The

district court found no evidence that this consent was a product of coercion,

emphasizing that Agent Perry displayed no weapons, used a cordial rather than

commanding tone, returned each object after searching it, conducted the search in

view of other citizens, and did not block the exits. The district court assigned

“negligible weight” to the fact that Ms. Valdez was not informed that she could

refuse to consent because she conceded at the suppression hearing that she

understood that she had that option. R., Vol. I, at 65. As for Ms. Valdez’s

4

Appellate Case: 13-2056 Document: 01019378505 Date Filed: 01/30/2015 Page: 4 
gender, the district court found no reason to suppose it had affected the agents’

behavior. Finally, the district court gave “little to no weight” to Ms. Valdez’s

national origin and alleged unfamiliarity with her constitutional rights because it

found no evidence that Agent Perry “knew of her educational background or of

any alleged unfamiliarity with her rights” and no “evidence that her citizenship

influenced Agent Perry in any way, other than his speaking to her in Spanish.” 

Id. at 66. Her motion having been denied, Ms. Valdez pleaded guilty while

reserving her right to appeal the denial.

The Presentence Investigation Report (“PSR”) prepared by the United

States Probation Office assigned Ms. Valdez a total offense level of twenty-eight,

a criminal history category of I, and a resulting advisory Guidelines range of

seventy-eight to ninety-seven months.3

 However, in light of the statutory

minimum of ten years, see 21 U.S.C. § 841(a)(1); id. § 841(b)(1)(A), it

recommended 120 months’ imprisonment. In its offense-level computation, the

PSR declined to recommend a mitigating-role adjustment under U.S.S.G. § 3B1.2. 

To explain that decision, the Probation Office emphasized that Ms. Valdez had

purchased her own tickets, concealed a significant amount of heroin on her

person, and transported drugs in the past, “suggesting a higher level of

involvement and knowledge of the drug organization.” R., Vol. II, at 5 (Second

3 The PSR used the 2011 version of the Guidelines, and we

accordingly do so as well.

5

Appellate Case: 13-2056 Document: 01019378505 Date Filed: 01/30/2015 Page: 5 
Addendum to PSR, dated Dec. 14, 2012). “Overall,” the Probation Office

concluded, “there is not enough evidence to determine an aggravating or

mitigating role.” Id.

Ms. Valdez objected to the PSR’s recommendation against a mitigating-role

adjustment, noting that she had done nothing other than to carry the drugs with

her. Given that fact, she urged the court to deem her a “minor participant” in the

offense as defined by U.S.S.G. § 3B1.2(b) and to accordingly reduce her offense

level by “at least two levels, if not three.” R., Vol. I, at 72 (Objection to PSR,

filed Dec. 14, 2012). The government opposed this adjustment, relying on the

following four propositions: (1) Ms. Valdez made inconsistent statements to the

authorities regarding her role in the organization; (2) she made multiple drugrunning trips on behalf of the organization, suggesting that she had “a higher

level of involvement and knowledge of the drug organization”; (3) Ms. Valdez

confessed “to being reimbursed for most of her trips,” indicating that “she clearly

was in control of her travel and therefore had to be in contact with the drug

trafficking organization more than she is admitting to or remembers”; and (4) the

amount of drugs given to Ms. Valdez suggested “that the drug trafficking

organization trusted her with a significant amount of their product.” Id. at 79–80

(Resp. to Def.’s Objection to PSR, filed Dec. 21, 2012) (internal quotation marks

omitted). 

The district court overruled the objection. From its perspective, the issue

6

Appellate Case: 13-2056 Document: 01019378505 Date Filed: 01/30/2015 Page: 6 
was “well-briefed, and . . . the government’s position [was] correct”; thus, the

court adopted the PSR’s factual findings and Guidelines recommendations. Id.,

Vol. III, at 91 (Sentencing Tr., dated Mar. 26, 2013).4

 The district court then

elected to disregard the statutory minimum, as authorized by the so-called

“safety-valve” provision, 18 U.S.C. § 3553(f); see United States v. A.B., 529 F.3d

1275, 1283–84 (10th Cir. 2008) (discussing the appropriate application of the

“safety-valve” provision), and sentenced Ms. Valdez to seventy months in federal

prison. Ms. Valdez timely appealed. 

II

On appeal, Ms. Valdez challenges the district court’s denial of her motion

to suppress based on its conclusion that she voluntarily consented to the agents’

search, as well as its denial of the minor-role adjustment at sentencing. As

explained below, the district court did not err in either regard. 

A

In reviewing the denial of Ms. Valdez’s motion to suppress, we “view[ ] the

evidence in the light most favorable to the government and uphold[ ] the district

court’s factual findings unless clearly erroneous.” United States v. Romero, 749

4 The district court stated that it was denying “the defendant’s request

for a downward departure,” R., Vol. III, at 91 (emphasis added), but it appears to

have been referring to the request for a minor-role adjustment. Ms. Valdez

understands the comment in those terms, and our analysis proceeds based on this

understanding. While Ms. Valdez did separately file a motion for a downward

variance, it is not relevant to the instant appeal.

F.3d 900, 903–04 (10th Cir. 2014) (quoting United States v. Danhauer, 229 F.3d

1002, 1005 (10th Cir. 2000)) (internal quotation marks omitted). While Ms.

Valdez urges that we must “review the district court’s determination of the

ultimate issue of voluntary consent de novo,” Aplt. Reply Br. at 2, she supports

this view with Fifth Amendment cases involving whether inculpatory statements

were voluntary. See Aplt. Reply Br. at 1 (citing United States v. Lamy, 521 F.3d

1257 (10th Cir. 2008), and United States v. Nguyen, 155 F.3d 1219 (10th Cir.

1998)). In the Fourth Amendment search-and-seizure context, however, we have

consistently maintained that “[w]hether consent was voluntarily given is a

question of fact we review for clear error.” United States v. Harrison, 639 F.3d

1273, 1277 (10th Cir. 2011); accord United States v. Davis, 636 F.3d 1281, 1292

(10th Cir. 2011); United States v. Silva-Arzeta, 602 F.3d 1208, 1213 (10th Cir.

2010).

We begin—and end—our analysis with the Supreme Court’s decision in

United States v. Drayton, 536 U.S. 194 (2002), which controls our resolution of

Ms. Valdez’s voluntariness claim. Ms. Valdez does not attempt to distinguish

between the facts of her case and the facts of Drayton—nor could she. The

defendants in Drayton were also traveling cross-country in a Greyhound bus when

the bus made a scheduled stop at a station. See 536 U.S. at 197. Three

officers—rather than the two here—then conducted virtually the same interdiction

effort undertaken by Agents Perry and Willatto. Specifically, they did not

8

Appellate Case: 13-2056 Document: 01019378505 Date Filed: 01/30/2015 Page: 8 
“obstruct[ ] the bus exit,” id. at 198, and did not “brandish a weapon,” id. at 204,

but instead politely “asked the passengers about their travel plans,” id. at 198,

specifically asked the defendants for consent to search their personal effects, and

then separately asked for consent to search their persons, see id. at 199. Like the

agents in this case, the officers in Drayton also did not inform the defendants of

their right to refuse the search request. See id. at 198. Further, while Ms. Valdez

emphasizes that her consent was non-verbal, one of the defendants

in Drayton also responded to the officer’s search request silently “by lifting his

hands about eight inches from his legs.” Id. at 199. 

Thus, under facts nearly identical to Ms. Valdez’s case, the Supreme Court

concluded that “[t]he respondents . . . were not seized and their consent to the

search was voluntary.” Id. at 200 (emphasis added).5

 While Ms. Valdez attempts

to avoid Drayton’s authority by limiting her challenge to the voluntariness of the

5 At oral argument, Ms. Valdez’s counsel asserted that Drayton’s

consent-to-search holding should not apply to Ms. Valdez because, unlike the

defendants in Drayton, she is foreign and therefore unlikely to be familiar with

the practices of U.S. law enforcement. However, we may not categorically

presume that national origin impacts the voluntariness of consent, and Ms. Valdez

fails to argue how her national origin affected her consent in particular. See

United States v. Girolamo, 23 F.3d 320, 327 (10th Cir. 1994) (“We [have]

rejected . . . any rule that would classify groups of travelers according to gender,

race, religion, national origin, or other comparable status, while recognizing that

they may be relevant in a particular case to the extent that they are objectively

apparent.”).

9

Appellate Case: 13-2056 Document: 01019378505 Date Filed: 01/30/2015 Page: 9 
search, rather than any alleged seizure,6

 this maneuver is flawed because

Drayton’s analysis applies to the voluntariness of consent to be searched as well. 

The Court explicitly held that “[i]n circumstances such as these, where the

question of voluntariness pervades both the search and seizure inquiries, the

respective analyses turn on very similar facts. And, as the facts above suggest,

respondents’ consent to the search of their luggage and their persons was

voluntary.” Id. at 206; see also United States v. Tapia, 309 F.3d 1283, 1289 (10th

Cir. 2002) (finding Drayton determinative of whether “proper consent [was]

obtained” in the context of a similar drug interdiction on a Greyhound bus). 

Ultimately, Ms. Valdez fails to persuade us that Drayton is distinguishable

from her case, and its holding leads inexorably to the conclusion that the district

court did not err in finding that her consent was voluntary.

B

Ms. Valdez also contends that the district court incorrectly construed the

Guidelines by relying on her knowledge of the drug-running scheme to deny her a

6 Although Ms. Valdez “maintains that she was seized when she was

confronted by [Agent] Perry on the bus,” she concedes that Drayton cuts against

her on the seizure issue and asserts that her “appeal focuses on the search and not

the seizure.” Aplt. Opening Br. at 14. “Focuses” is a somewhat ambiguous term,

and Ms. Valdez could be understood to suggest that she advances both a search

and a seizure argument and simply devotes more attention to the former. 

However, given that she nowhere articulates a challenge to the constitutionality of

any alleged seizure, and indeed, asserts that her citations to seizure caselaw are

meant only to substantiate her involuntary-consent arguments, we perceive her

challenge to be confined to the voluntariness of the search. 

10

Appellate Case: 13-2056 Document: 01019378505 Date Filed: 01/30/2015 Page: 10 
§ 3B1.2(b) mitigating-role adjustment for being a minor participant. Ms.

Valdez’s challenge is one of procedural unreasonableness, see United States v.

Martinez, 512 F.3d 1268, 1275 (10th Cir. 2008) (reviewing the denial of a

§ 3B1.2 minor-participant adjustment under the procedural-reasonableness

rubric), and, as such, we review “de novo the district court’s legal conclusions

regarding the guidelines and its factual findings for clear error,” United States v.

Gantt, 679 F.3d 1240, 1246 (10th Cir. 2012); accord United States v. Mollner,

643 F.3d 713, 714 (10th Cir. 2011). 

The Guidelines instruct district courts to decrease an offense level by four

levels where “the defendant was a minimal participant in any criminal activity,”

U.S.S.G. § 3B1.2(a), by two levels where “the defendant was a minor

participant,” id. § 3B1.2(b), and by three levels where the defendant falls between

the two, see id. § 3B1.2.7

 As relevant here, two application notes clarify the

significance of these sentencing provisions. The first explains that a “defendant’s

lack of knowledge or understanding of the scope and structure of the enterprise

and of the activities of others is indicative of a role as minimal participant.” Id.

§ 3B1.2 cmt. n.4. The second explains that a “minor participant” is one “who is

less culpable than most other participants, but whose role could not be described

7 Before the district court, Ms. Valdez asked for a reduction of “two

levels, if not three.” R., Vol. I, at 72. On appeal, her argument focuses only on

the two-level minor-participant adjustment, so we do not analyze her eligibility

for a three-level “in-between” adjustment. 

11

Appellate Case: 13-2056 Document: 01019378505 Date Filed: 01/30/2015 Page: 11 
as minimal.” Id. § 3B1.2 cmt. n.5.8

Ms. Valdez’s sentencing argument on appeal is a narrow one. She faults

the district court for impermissibly basing its § 3B1.2 ruling on “the level of [her]

knowledge or understanding of the scope and structure of the drug enterprise,”

because, she claims, the application notes suggest that knowledge is only relevant

to whether she is a minimal participant under the Guidelines, not to whether she is

a minor participant. Aplt. Opening Br. at 25. This argument fails because, to the

extent that the court relied on Ms. Valdez’s knowledge,9

 it did not commit legal

8 “Commentary in the Guidelines Manual that interprets or explains a

guideline is authoritative unless it violates the Constitution or a federal statute, or

is inconsistent with, or a plainly erroneous reading of, that guideline.” United

States v. Boyd, 721 F.3d 1259, 1261 (10th Cir.) (quoting United States v. Nacchio,

573 F.3d 1062, 1066–67 (10th Cir. 2009)) (internal quotation marks omitted),

cert. denied, --- U.S. ----, 134 S. Ct. 630 (2013). We have previously relied upon

the application notes discussed above. See, e.g., United States v. MontoanHerrera, 351 F.3d 462, 465 (10th Cir. 2003). 

9 Arguably, the district court’s decision did not turn on Ms. Valdez’s

knowledge, per se, but rather on her active involvement in the drug operation. 

The court adopted the stance taken by the government, which rested on the

following propositions: (1) Ms. Valdez made inconsistent statements to the

authorities regarding her role in the organization; (2) she made multiple drugrunning trips on behalf of the organization; (3) she confessed “to being

reimbursed for most of her trips”; and (4) the amount of drugs given to Ms.

Valdez suggested “that the drug trafficking organization trusted her with a

significant amount of their product.” R., Vol. I, at 79–80. While the government

labeled these facts as evidence of Ms. Valdez’s “knowledge,” it also suggested

that they indicated her “higher level of involvement” in the operation. Id., Vol.

II, at 5. Indeed, her multiple, reimbursed, drug-running trips and the significant

drug quantity involved clearly demonstrate the active role she played in the

organization. And Ms. Valdez never claims that personal involvement in the

relevant criminal conduct is an illegitimate consideration in the minor-participant

(continued...)

12

Appellate Case: 13-2056 Document: 01019378505 Date Filed: 01/30/2015 Page: 12 
error in doing so. 

Ms. Valdez’s argument is bereft of any citations to cases excluding

knowledge from the minor-participant calculus, and indeed, the weight of

authority is decidedly against her position. We have previously looked to a

defendant’s knowledge in determining whether an offense-level reduction under

U.S.S.G. § 3B1.2 applies. See, e.g., Adams, 751 F.3d at 1180 (finding the

defendant’s “knowledge of the scheme” to rob a bank relevant to the

determination that he was not a minor participant); United States v. Ayers, 84

F.3d 382, 384 (10th Cir. 1996) (concluding that the defendant was not a minor

participant where he “knowingly permitted [a codefendant] to use [his] apartment

to sell drugs”); United States v. Lockhart, 37 F.3d 1451, 1455 (10th Cir. 1994)

(noting that the PSR revealed that the defendant had “knowledge or

understanding” of the drug enterprise and he was thus “not a minimal or minor

participant” (emphasis added) (internal quotation marks omitted)). 

Several of our sister circuits have similarly blessed the consideration of

9

(...continued)

analysis, nor could she plausibly do so. See, e.g., United States v. Adams, 751

F.3d 1175, 1180 (10th Cir.) (noting the defendant’s “involvement in the robbery”

as a lookout was indicative that he was not a minor participant), cert. denied, ---

 U.S. ----, 135 S. Ct. 292 (2014); United States v. Mendoza, 468 F.3d 1256, 1264

(10th Cir. 2006) (affirming the denial of a minor-participant adjustment where

evidence “indicated that [the defendant] was not fully disclosing his

involvement”); United States v. Jefferson, 925 F.2d 1242, 1260 n.23 (10th Cir.

1991) (“[G]iven the evidence of his substantial involvement in the offenses, we

do not find the district court’s decision [denying the defendant a § 3B1.2

adjustment] to be clearly erroneous.”). 

13

Appellate Case: 13-2056 Document: 01019378505 Date Filed: 01/30/2015 Page: 13 
knowledge as part of the minor-participant analysis. See, e.g., United States v.

Pinkin, 675 F.3d 1088, 1090 (8th Cir. 2012) (noting that a defendant “had

extensive knowledge of the conspiracy” in explaining why “[t]he district court did

not clearly err in denying . . . a minor participant role-in-the-offense reduction”);

United States v. Minutoli, 374 F.3d 236, 238 (3d Cir. 2004) (affirming a sentence

where the district court denied a minor-participant adjustment in part because of

the defendant’s “knowledge of . . . the nature and scope of the enterprise”);

United States v. Nguyen, 255 F.3d 1335, 1345 (11th Cir. 2001) (finding that the

district court did not err in relying on the defendant’s “knowledge of the

operation, coupled with his conduct,” to conclude that “his role in the enterprise

was not so minor as to warrant a[n adjustment] pursuant to § 3B1.2(b) of the

Guidelines”). 

That Ms. Valdez cannot provide—nor can we locate—legal authority

supporting the view that knowledge is not part of the minor-participant analysis is

unsurprising given the tenuousness of her argument. Under the application notes,

a “minor” participant is one whose role is not “minimal,” U.S.S.G. § 3B1.2(b)

cmt. n.5, and a “minimal” participant is one whose “lack of knowledge or

understanding” renders him “plainly among the least culpable,” id. § 3B1.2(b)

cmt. n.4. The logical implication of the application notes is, therefore, that a

minor participant is distinguished, in part, from a minimal participant based on

his relative knowledge and understanding of the criminal operation. 

14

Appellate Case: 13-2056 Document: 01019378505 Date Filed: 01/30/2015 Page: 14 
“Knowledge” and “understanding” are not binary terms, but instead fall on a

spectrum; a greater degree of ignorance might move one closer to the minimalparticipation category, and a lesser degree of ignorance might move one closer to

the minor-participation category. See United States v. Maldonado-Campos, 920

F.2d 714, 718 (10th Cir. 1990) (“[T]he terms ‘minimal participant’ and ‘minor

participant’ are not too distant points along a continuum of moderate criminal

participation.”).

In sum, the district court did not err in denying the adjustment because it

could permissibly rely on Ms. Valdez’s knowledge of the drug organization. 

III

Because we find no error in the district court’s conclusions that Ms. Valdez

voluntarily consented to a search of her person and that she was not a minor

participant in the drug-running scheme, we hereby AFFIRM her conviction and

sentence.
