H A R T Z, Circuit Judge.


      M anuel de Jesus Cruz-M endez was convicted in the United States District

Court for the District of Utah on a charge of illegal reentry into the United States
after a bench trial on stipulated evidence. See 8 U.S.C. § 1326. On appeal he

challenges the district court’s denial of his motion to suppress evidence because

of alleged violations of the Fourth Amendment. W e have jurisdiction under

28 U.S.C. § 1291 and affirm the conviction and sentence. W e hold that (1) the

law-enforcement officers’ “knock and talk” was not a Fourth Amendment

intrusion; (2) the district court did not clearly err in finding that M r. Cruz-

M endez’s girlfriend, Olga Armenta, consented to the officers’ entrance into the

living room of her apartment; (3) the cellular phone observed by the officers in

the apartment living room was in plain view ; (4) the district court did not clearly

err in finding that M s. Armenta consented to a search of the bedroom; and (5) the

officers had probable cause to arrest M r. Cruz-M endez. Because we conclude

that there were no Fourth Amendment violations, we need not address w hether a

violation would require that M r. Cruz-M endez’s identity be suppressed.

I.    BACKGROUND

      W e summarize the evidence offered at the suppression hearing in the light

most favorable to the district court’s decision. See United States v. Hunnicutt,

, 1348 (10th Cir. 1998). On December 17, 2004, Department of

Homeland Security (DHS) Agent Leslie Derewonko received a phone call from a

female concerning a man named M anuel Cruz-M endez. The caller said that he

had previously been deported, he had several previous narcotics convictions, and



                                           -2-
her husband had seen him at a particular address in Provo that morning. That

address turned out to be an apartment rented by M r. Cruz-M endez’s girlfriend,

M s. Olga Armenta.

      Agent Derewonko asked fellow DHS Security Agent Carlos G amarra to

meet him at the apartment, and also contacted the Provo Police D epartment so

that he and Agent Gamarra, who were in civilian clothes, could have uniformed

officers with them.

      At 8:00 a.m. Agents Derewonko and Gamarra, along with Officer Brian

M oore of the Provo Police Department, went to the apartment. M s. Armenta’s

brother answered their knock on the door. He was putting on his coat and about

to leave. The officers introduced themselves but did not enter the apartment.

W hen Agent Derewonko asked the brother for identification, he produced a green

card. M s. Armenta, who gave her name as Olga, was sitting in the room behind

her brother; she was dressed in pajamas. One of the officers asked M s. Armenta

and her brother whether they knew a M anuel Cruz-M endez. Both responded that

they did not know him and that there was no one else in the apartment.

      After this brief exchange the officers left the apartment and returned to the

parking lot. Officer M oore spoke with Provo Police Officer Brad M acFarlane,

who said that a few days earlier he had received a call from an anonymous female

who had provided the same information received by Agent Derewonko. The



                                        -3-
caller had further stated that M r. Cruz-M endez was staying with his girlfriend,

Olga. Officer M acFarlane also told O fficer M oore that he understood that there

was a Salt Lake City arrest warrant on a narcotics charge for a M r. M anuel Cruz.

      The officers saw M s. Armenta’s brother leave the apartment shortly after

they received this information. The officers, now accompanied by Officer

M acFarlane, returned to the apartment at 8:20 a.m. and knocked again.

M s. Armenta answered the door. Agent Derewonko told M s. Armenta that the

officers had received information that she and M r. Cruz-M endez’s girlfriend had

the same name. She again said that there was no one else in the apartment.

Agent Derewonko then asked M s. Armenta if the officers could step into the

apartment because of the cold weather, and she invited them in.

      Once inside, Agent Derewonko asked M s. Armenta for identification to

confirm her name. She stated that it was in her car and left the apartment to get

it. As she retrieved it, the officers waited outside her apartment. They did not

enter again until she returned with a Utah driver’s license, when she again let

them in.

      At 8:35 a.m. one of the Provo police officers ran a check on M s. Armenta’s

license; it was valid. Agent Derewonko then asked if he could look into the

bathroom for the safety of the officers. M s. Armenta consented, so Agent

Derewonko, with M s. Armenta following him, inspected the bathroom. W hen the



                                         -4-
pair returned to the living room, she found the other officers looking at pictures in

the living room. M s. Armenta expressed her displeasure that they were looking

around the living room and at the pictures, but she did not ask them to leave.

      Agent Derewonko then asked M s. Armenta what her immigration status

was. W hen she said that she was a legal resident, he requested documentation.

She went to her bedroom to get proof, but refused to allow Agent Derewonko to

come with her. W hen she returned with her green card, he made a telephone call

to verify its immigration number. Agent Derewonko then asked if he could search

the apartment, and she refused. Agents D erewonko and Gamarra repeated this

request one or two more times, but she continued to refuse. She said that they

could search only if they had a w arrant. Agent Gamarra explained the procedure

for obtaining a warrant (including preparation of an affidavit for review by the

United States Attorney and then submission to a judge for approval) and that she

could be arrested for harboring if M r. Cruz-M endez were found in the apartment.

(The district court’s narrative of its findings says that “A gent Gamarra then told

her that if the officers w ere not permitted to search the apartment, he would

obtain a warrant.” R. Doc. 48 at 7 (District Court M emorandum Decision and

Order of July 1, 2005 (District Court Decision)) (emphasis added). But the

testimony at the suppression hearing, including M s. Armenta’s testimony,

indicates that the officers spoke only of seeking a warrant. In any event, the



                                         -5-
conclusions we reach in this case do not turn on the distinction between a

statement by the officers that they would get a warrant and

a statement that they would seek a warrant.) M s. Armenta asked some questions

about the warrant procedure and then said, “[F]ine, go get a search warrant.” R.

Vol. II at 122. Although she testified that the officers threatened that if they got a

warrant they would break the doors and take everything out of the closet, they

denied that they made such a threat, testifying that they had said only that they

could look anywhere a person could hide. The district court believed the officers.

      The officers were about to leave to seek a w arrant when Officer M oore

noticed a black jacket on a love seat next to the officers. To him this “seemed

suspicious because a male had just left putting a coat on, but yet we’ve got

another male’s jacket laying [sic] as though they are preparing to leave or had just

come in.” 

He then “shined his flashlight on the jacket and noticed a

cell phone protruding from the pocket. W hile he did not touch the jacket, he bent

over, shined a flashlight on the phone, and inspected the phone.” R. Doc. 48 at 7

(District Court Decision). The name “CRUZ” was etched (perhaps with a

ballpoint pen) on the phone. Officer M oore then drew Agent Gamarra’s attention

to the phone; Agent Gamarra was able to see the word “CRUZ” without the

flashlight and without touching the jacket.




                                         -6-
      Noticing that the officers had seen the cellular phone, M s. Armenta became

upset. She directed Agent Gamarra outside, where she confirmed that M r. Cruz-

M endez was in the bedroom closet. She told Agent Gamarra that he could search

the bedroom, but she asked the officers to pretend to enter without her consent

because she was afraid of M r. Cruz-M endez.

      After securing the rest of the apartment, Agents Gamarra and Derewonko

found M r. C ruz-M endez hiding under a pile of clothes in the bedroom closet.

They arrested him and read the M iranda warnings. He gave his name as M anuel

Cruz-M endez. About 25 or 30 minutes had passed since the officers first entered

the apartment; a Provo Police Department Call for Service report indicates that, in

the w ords of O fficer M oore, they were “completely done” by 9:00 a.m. R. Vol. II

at 195. The officers later discovered that the arrest w arrant from Salt Lake City

was not for M r. Cruz-M endez but for a man named M anuel Camarillo Cruz.

      M r. Cruz-M endez was charged with illegal reentry under 8 U.S.C. § 1326.

He moved to suppress all evidence in the case, claiming violations of the Fourth

Amendment. After conducting an evidentiary hearing, the district court issued a

written decision and order holding that M r. Cruz-M endez had standing to contest

the officers’ search but denying his motion to suppress evidence.




                                         -7-
      M r. Cruz-M endez was found guilty on August 17, 2005, after a bench trial

on stipulated evidence. He was sentenced to a term of 57 months in federal

prison.

II.   D ISC U SSIO N

      W hen review ing a district court’s denial of a motion to suppress, we

consider the totality of the circumstances and view the evidence in the light most

favorable to the government. See 

. “W e accept the

district court’s factual findings unless those findings are clearly erroneous.”

United States v. Villa-Chaparro, 

, 801 (10th Cir. 1997).

      A.     “K nock and Talk”

      M r. Cruz-M endez first contends that the officers lacked reasonable

suspicion for the initial approach to the apartment to conduct a so-called “knock

and talk” investigation. B ut reasonable suspicion was unnecessary. As

commonly understood, a “knock and talk” is a consensual encounter and therefore

does not contravene the Fourth Amendment, even absent reasonable suspicion.

See United States v. Spence, 

, 1283 (10th Cir. 2005) (“There is no

per se rule that a police encounter within an individual’s home is a seizure within

the meaning of the Fourth Amendment.”); United States v. Thom as, 

,

277 (6th Cir. 2005) (“A number of courts . . . have recognized ‘knock and talk’

consensual encounters as a legitimate investigative technique at the home of a



                                         -8-
suspect or an individual with information about an investigation.”); United States

v. Cormier, 

, 1109 (9th Cir. 2000) (“[N]o suspicion needed to be

shown in order to justify the ‘knock and talk.’”).

      M r. Cruz-M endez’s reliance on United States v. Jones, 

,

720–21 (5th Cir. 2001), is misplaced. In Jones the issue was whether a police

officer’s plain view of a handgun inside an apartment during a “knock and talk”

improperly created the exigent circumstances that justified a w arrantless entry

into the home. 

Rather than questioning the propriety of a “knock

and talk,” the court observed that “[f]ederal courts have recognized the ‘knock

and talk’ strategy as a reasonable investigative tool when officers seek to gain an

occupant’s consent to search or when officers reasonably suspect criminal

activity.” 

(emphasis added). The court ultimately held the w arrantless

entry to be justified. 

      In short, the officers in this case did not need reasonable suspicion before

knocking on M s. Armenta’s door with the intent to ask her questions. W hether

any of their later actions constituted an unlawful search or seizure is the subject

of the remainder of our discussion.

      B.     E ntry into L iving R oom




                                         -9-
      M r. Cruz-M endez apparently contends that M s. Armenta did not consent to

the officers’ presence in her living room during their second visit to the

apartment. The district court held that she voluntarily consented.

      Consent can justify an entry into a home, regardless of whether there is

probable cause. See United States v. Sawyer, 

, 894 (10th Cir. 2006).

But consent is valid only if it is “freely and voluntarily given.” 

marks omitted). W hether consent satisfies this requirement is “a factual

determination based upon the totality of the circumstances.” 

uphold a district court’s factual findings regarding consent “unless they

are clearly erroneous.” 

is clearly erroneous w hen although there is

evidence to support it, the reviewing court on the entire evidence is left with the

definite and firm conviction that a mistake has been committed.” United States v.

De la Cruz-Tapia, 

, 1277 (10th Cir. 1998) (internal quotation marks

and brackets omitted). The clearly-erroneous standard is “significantly

deferential.” Concrete Pipe & Prods. of Cal., Inc. v. Constr. Laborers Pension

Trust, 

, 623 (1993). Our deference to the district court’s factual

findings is even greater w hen the credibility of witnesses is at issue. See

Anderson v. City of Bessemer City, 

, 575 (1985) (interpreting Fed. R.




                                         -10-
Civ. P. 52(a)); United States v. Little, 

, 713 (10th Cir. 1995) (applying

Anderson to appellate review of findings at suppression hearing).

      The district court found that M s. Armenta’s consent to the officers’

entering her apartment “was unequivocal and freely given with no duress.”

R. Doc. 48 at 11 (District Court Decision). The court observed that although

M s. Armenta was apparently not pleased that the officers had been looking around

her living room while she and Agent Derewonko inspected the bathroom, she did

not ask them to leave.

      M r. Cruz-M endez claims that any consent was necessarily coerced by the

presence of multiple officers and the officers’ request for identification and, later,

proof of legal status. The presence of several officers is, however, not

dispositive. See United States v. Ledesma, 

, 1314 (10th Cir. 2006)

(providing list of factors, none of w hich is dispositive). Nor does a mere request

for identification render a consent involuntary. Cf. United States v. Evans, 

, 1537–38 (10th Cir. 1991) (request to see identification can be a non-

coercive, consensual encounter not implicating the Fourth Amendment). The

officers testified that they acted courteously and did not draw their weapons. She

gave consent to enter soon after they came to her door the second time. See

United States v. Benally, 

, 1239–40 (10th Cir. 1998) (length of

interviews with defendant relevant in determining whether consent w as coerced).



                                         -11-
And she invited them in again after she retrieved her license. In addition, the

court could properly view her state of mind in hindsight; one can now infer that

her concern was that the officers not enter the bedroom, and that she was not

reluctant for them to enter the rest of the apartment. The district court’s finding

of voluntariness was not clearly erroneous.

      C.     V iew of C ellular Phone

      The district court ruled that the officers’ view of the cellular phone etched

with the name “CRUZ” was lawful because the phone was in plain view.

M r. Cruz-M endez contends that this ruling was erroneous. W e review de novo

the district court’s ruling. See United States v. Thom as, 

, 1178

(10th Cir. 2004).

      The only issue here is whether the officers’ observation of the cellular

phone violated the Fourth Amendment. M r. Cruz-M endez would have us analyze

the legality of this observation under the plain-view doctrine governing the

seizure of items in plain view; he contends that the requirements of that doctrine

were not satisfied. But, as the Supreme Court has stated, “It is important to

distinguish ‘plain view,’ as used in Coolidge [v. New Ham pshire, 

(1971)] to justify seizure of an object, from an officer’s mere observation of an

item left in plain view. . . . [T]he latter generally involves no Fourth Amendment

search.” Texas v. Brown, 

, 738 n.4 (1983). For a mere observation



                                         -12-
to be valid, the only requirement is that the officer be lawfully in a position from

which he can view the object. See 

740–41; United States v. Gonzales-

Acosta, 

, 387 (10th Cir. 1993). W e have already concluded that

M s. Armenta voluntarily consented to the officers’ presence in the living room.

The officers were thus lawfully in a position from which they could view the

cellular phone. See 

.

      M r. Cruz-M endez appears to contend that the use of a flashlight converted

the observation into a Fourth Amendment search. W e note, however, that the

district court found that Agent Gamarra was able to read the word “CRU Z”

without the aid of the flashlight. In any event, the “use of artificial means to

illuminate a darkened area simply does not constitute a search, and thus triggers

no Fourth Amendment protection.” Brown, 460 U .S. at 740. The officers’

observation of the cellular phone did not violate the Fourth Amendment.

      D.     Search of the B edroom

      M r. Cruz-M endez claims that M s. Armenta’s consent for the officers to

search the bedroom was coerced. The district court found that M s. Armenta had

verbally consented to the search of her bedroom and that her consent was made

“unequivocally, specifically, freely, and intelligently,” without coercion by the

officers. R. Doc. 48 at 12 (District Court Decision). As we have already




                                         -13-
discussed, we review only whether the factual findings regarding consent were

clearly erroneous. See 

.

      W e cannot say that the district court’s findings were clearly erroneous.

Although M s. Armenta testified that she never consented to a search of the

apartment, Agent Gamarra testified to the contrary and the district court credited

his testimony. W e see no reason not to defer to the court’s credibility

determination.

      As for coercion, M r. Cruz-M endez contends that the officers’ questioning

of M s. Armenta w ithout reasonable suspicion and the fact that M s. Armenta is

“presumptively uneducated,” Aplt. Br. at 24, render her consent involuntary.

There is no merit to these arguments. Because we have already held that

M s. Armenta consented to the officers’ presence in the living room, the officers

were not required to have reasonable suspicion for their questioning. And there is

nothing in the record to indicate that M s. Armenta was uneducated.

      M r. Cruz-M endez also points, however, to several additional, more

significant circumstances: the presence of several armed officers, the length of

time the officers were in the apartment, and the officers’ statement that they

would get a search warrant if M s. Armenta did not consent. His argument is

hardly frivolous and could have persuaded a rational fact-finder that the consent

was involuntary. But it does not require setting aside the district court’s finding.



                                        -14-
      First, the district court explicitly found that the officers w ere not overly

threatening or forceful. Second, although the officers’ encounter with

M s. Armenta w as more than momentary, the length did not necessarily make it

overbearing. The district court found that the officers’ second visit to

M s. Armenta’s apartment lasted approximately 30 minutes before M r. Cruz-

M endez was arrested. (The court’s time frame is consistent with the Provo Police

Department Call for Service report, which indicates that M s. Armenta’s license

was verified at 8:35 a.m. and that the arrest was completed by 9:00 a.m.) During

that period M s. Armenta had left to retrieve her license from the car, Agent

Derewonko had searched the bathroom, M s. Armenta had retrieved her green

card, she had her conversation with Agent Gamarra outside, and the officers

secured the apartment, searched the bedroom closet, and arrested M r. Cruz-

M endez. This was not the equivalent of a lengthy interrogation in a bare room

while the subject sits on a stool until her w ill is overborne. Cf. 

(statement following one-and-a-half-hour interview after

M iranda warning was not coerced); United States v. Strache, 

, 986

(7th Cir. 2000) (defendant who was handcuffed for 20 minutes before consenting

nonetheless did so voluntarily); United States v. French, 

, 693 (6th

Cir. 1992) (45 minutes between stop and consent did not amount to coercion);

United States v. Tyson, 

, 806 (E.D. Va. 2005) (consent given



                                          -15-
30 minutes after officers arrived; finding of voluntariness supported by initial

refusal to permit w arrantless search).

      M ost helpful to M r. Cruz-M endez is A gent Gamarra’s assertion to

M s. Armenta that he would get a search warrant if she did not consent. But such

statements are not per se coercive. See U nited States v. Severe, 

, 446

(8th Cir. 1994) (officers’ statement that they would obtain a search warrant “only

one factor in the totality of the circumstances”); United States v. White, 

, 542 (7th Cir. 1992) (although baseless threats to obtain a warrant may render

consent involuntary, an expression of a genuine intent to obtain one does not);

United States v. Hummer, 

, 190 (4th Cir. 1990) (“The fact that a

search warrant was mentioned does not necessarily constitute a coercive factor

negating consent.” (internal quotation marks omitted)); United States v. Agosto,

, 614 (9th Cir. 1974) (officer’s statement that he would obtain a

warrant if consent not given is “not conclusive as a matter of law ”); cf. United

States v. Culp, 

, 462 (8th Cir. 1973) (defendant’s consent valid even

though it followed officer’s statement that a search warrant was being procured,

because defendant consented for an independent, voluntary reason). One must

still examine the particulars of the case.

      The district court had two weighty reasons for not finding that Agent

Gamarra’s assertion improperly overpowered M s. Armenta’s will. First, the



                                          -16-
assertion did not in itself cause M s. Armenta to consent. W hen told how the

officers could procure a warrant, she said, “[F]ine, go get a search warrant.”

R. Vol. II at 122. She changed her mind only when the officers discovered the

cellular phone w ith “CRUZ” etched on it. At that point she knew that the officers

had caught her in a lie. The district court could have reasonably inferred that the

psychological impact of this realization was more pow erful than the officers’

assertion that they would get a w arrant. It stated that M s. Armenta “readily

consented” only after she realized that the phone had been discovered. R. Doc.

48 at 12 (District Court Decision). Second, even if Agent Gamarra’s original

assertion that they would get a warrant was improperly coercive because the

officers clearly lacked the requisite probable cause, that assertion was likely true

by the time the assertion bore any fruit (namely, M s. Armenta’s consent). W hen

the officers found a man’s coat in the apartment with a cellular phone labeled

“CRUZ” in the pocket, after M s. Armenta and her brother had denied knowing a

M r. Cruz-M endez, they probably had sufficient additional information to procure

a warrant. See 

(expression of genuine intent to obtain

warrant “does not vitiate consent”).

      W e hold that the district court did not clearly err when it found that

M s. Armenta voluntarily consented to the search of the bedroom.

      E.     T he A rrest



                                         -17-
      M r. Cruz-M endez contends that the officers lacked probable cause to arrest

him at the apartment. The district court concluded that the officers had probable

cause. W e review this determination de novo. See United States v. Dozal, 

, 792 (10th Cir. 1999). As this court has previously stated:

      Probable cause to arrest exists only when the facts and circumstances
      within the officers’ knowledge, and of which they have reasonably
      trustw orthy information, are sufficient in themselves to warrant a
      man of reasonable caution in the belief that an offense has been or is
      being committed. Probable cause does not require facts sufficient for
      a finding of guilt; however, it does require more than mere suspicion.
      Probable cause is measured against an objective standard. The
      primary concern is whether a reasonable officer would have believed
      that probable cause existed to arrest the defendant based on the
      information possessed by the arresting officer.

      W e agree with the district court. The officers began with anonymous tips

that a previously deported felon named M anuel Cruz-M endez was at a particular

address. Such tips are in themselves entitled to little weight. But the followup

investigation provided substantial corroboration. First, the officers’ identification

of Olga Armenta corroborated one caller’s tip that M r. Cruz-M endez was staying

with his girlfriend Olga at the apartment. Second, the officers’ discovery of a

man’s jacket containing a cellular phone etched with the name “CRU Z”

corroborated the presence of M r. Cruz-M endez at this address, particularly since

the discovery indicated that M s. Armenta had lied when she had been asked

                                          -18-
whether she knew a M r. Cruz-M endez. Third, M s. Armenta’s admission outside

the apartment that she had been lying about M r. Cruz-M endez’s presence, that she

feared him, and that he was hiding served to corroborate the anonymous tips

regarding his location and history and to indicate that he was living in the

apartment and was avoiding law-enforcement authorities. Fourth, the discovery

of M r. Cruz-M endez hiding under clothing in a closet further corroborated the

tw o anonymous calls, and demonstrated his consciousness of guilt. Cf. United

States v. Fernandez, 

, 879 n.4 (10th Cir. 1994) (“It is well recognized

that a defendant’s intentional flight from police officers may be used as

circumstantial evidence of guilt.”). And fifth, at the time of the arrest the officers

knew that there was a warrant issued out of Salt Lake City for a man named

M anuel Cruz. Cf. Hill v. California, 

, 802 (1971) (“W hen the police

have probable cause to arrest one party, and when they reasonably mistake a

second party for the first party, then the arrest of the second party is a valid

arrest.” (internal quotation marks and brackets omitted)). The totality of this

information established probable cause to arrest M r. Cruz-M endez.

      Finally, M r. Cruz-M endez, citing Payton v. New York, 

(1980),

claims that “where as here, the police do not have an arrest warrant, they may not

arrest a person in his home even with probable cause, absent exigent

circumstances.” Aplt. Br. at 26. But Payton holds only that “the Fourth



                                         -19-
Amendment . . . prohibits the police from making a warrantless and

nonconsensual entry into a suspect’s home in order to make a routine felony

(emphasis added). Because we have held that the

officers’ entry into the bedroom was consensual, Payton does not apply.

III.   C O N C L U SIO N

       The district court’s findings support the conclusion that the officers’

conduct did not violate the Fourth A mendment. W e need not address the parties’

arguments regarding whether such a violation would require suppression of

M r. Cruz-M endez’s identity. W e AFFIRM the judgment below.
