RILEY, Circuit Judge.

       Celso Tirado (Tirado) was charged with and convicted of conspiracy to
distribute methamphetamine (Count I) and charged with possession of
methamphetamine with intent to distribute (Count II), but was convicted of the lesser
included offense of possession of methamphetamine. 21 U.S.C. §§ 841(a)(1), 846
(2000). The district court1 sentenced Tirado to 121 months imprisonment on Count
I and six months on Count II, to run concurrently. Tirado alleges the district court

of Nebraska.
erred in (1) denying his motion to suppress, (2) calculating the quantity of
methamphetamine used for sentencing, and (3) applying the obstruction of justice
enhancement. We affirm.

I.     BACKGROUND
        On August 24, 2000, Jeff and Paul Schwarz, criminal investigators with the
Dawson County, Nebraska, Sheriff's Office (DCSO), used a confidential informant
to make a controlled purchase of methamphetamine from Tirado and another man at
a bar in Lexington, Nebraska. After the informant spent a short time in the bar, he
came out with Tirado. Tirado lifted up his own shirt and appeared to try to get the
informant to raise his shirt, as if looking for a hidden wire. The informant ran from
Tirado, and Tirado chased him first on foot and then in his Chevy Blazer. The
informant took refuge in the officers’ unmarked vehicle. Tirado pursued the
informant and the officers in his Blazer and cornered them in an alley. Believing they
were ambushed, the officers drew their weapons and pointed them at Tirado, who
then drove away.

       About two months later, law enforcement officers received information that
Tirado and another man had made death threats against the investigators, Jeff and
Paul Schwarz, and their families. Halloween night was the rumored attack date. On
the afternoon of October 31, 2000, three DCSO officers and two INS officers went
to Tirado's residence to investigate the death threats and to execute a bench warrant
for Tirado's arrest. When the officers arrived, Armando Quezada (Quezada) answered
the door. When an INS agent asked for identification, Quezada appeared nervous,
turned away and moved quickly into the trailer. Fearing that Quezada might be
running out the back or retrieving a weapon, the INS agent and Jeff Schwarz followed
Quezada into the trailer. Once inside, the officers noticed drug paraphernalia. Upon
request by the officers, Quezada gave permission to search his bedroom, resulting in
the discovery of illegal drugs.



                                         -2-
      While officers were inside the trailer, Tirado approached outside. Paul
Schwarz confronted Tirado and arrested him pursuant to the bench warrant. Schwarz
advised Tirado of his rights. According to the officers, Tirado gave Schwarz
permission to search his bedroom. Tirado denies giving his permission.

       While searching Tirado’s bedroom, an officer saw a book bag hanging in the
closet. The officer searched the bag and found a scale, methamphetamine,
ammunition and cash. Tirado later admitted the bag was his and contained
ammunition. He denied knowing the bag contained drugs or drug paraphernalia. The
total methamphetamine found in Tirado's residence was 128.72 grams, which Tirado
moved to suppress. The district court denied this motion.

       At trial, two witnesses testified they received an additional 99.05 grams of
methamphetamine from Tirado. At sentencing, the district court attributed 227.77
grams of methamphetamine to Tirado as relevant conduct to the conspiracy. In
addition, the district court applied a two-level obstruction of justice enhancement for
Tirado’s conduct on August 24. The district court sentenced Tirado to 121 months
imprisonment on Count I and a concurrent six months on Count II.

II.   DISCUSSION
      A.    Motion to Suppress
      We review the district court's factual findings for clear error and the
conclusions of law de novo. See United States v. Wells, 

, 838 (8th Cir.
2000). The district court's finding of consent to search is reviewed for clear error.
United States v. Heath, 

, 1276 (8th Cir. 1995).

      Tirado claims the warrantless search of his residence violated the Fourth
Amendment’s protection against unreasonable search and seizure, and the items
found should have been suppressed. First, Tirado argues the officers unlawfully
followed Quezada into the residence. Second, Tirado argues he never consented to

                                         -3-
a search, but if he had, the officers exceeded the scope of his consent to search his
bedroom when they searched his closet and a closed bag hanging in the closet. The
magistrate judge2 and the district court provided detailed and well-reasoned opinions
on these issues and we affirm with little comment.

       The officers went to Tirado’s residence to execute a bench warrant for Tirado’s
arrest and to investigate death threats allegedly made by Tirado against Jeff and Paul
Schwarz. These duties were carried out against the backdrop of the earlier dangerous
chase involving Tirado. Viewed in light of these facts, when Quezada appeared
nervous and abruptly retreated into the residence, the officers were justified in
following Quezada to protect themselves. See United States v. Hill, 

,
1170 (8th Cir. 1984) (“entry into the living room to locate [the defendant] was
justified to protect the officers”).

       The district court did not err in finding Tirado voluntarily consented to a search
of his bedroom based on the credibility of the officers’ testimony. See Schneckloth
v. Bustamonte, 

, 227 (1973) (voluntary consent to search is a fact
question determined from the totality of the circumstances). As Tirado did not limit
the scope of the search of his bedroom, the officers did not violate Tirado’s Fourth
Amendment rights by searching the bedroom closet and the bag hanging in the closet.
See Florida v. Jimeno, 

, 251 (1991) (because the scope of the suspect's
consent to search his automobile was not limited, the search authorization "extended
beyond the surfaces of the car's interior to the paper bag lying on the car's floor");
United States v. Moran, 

, 951 (8th Cir. 2000) (consent to search trailer
included searching a tin box on an upper shelf in a bedroom closet); United States v.
Coffman, 

, 953 (8th Cir. 1998) (consent to search home included
searching under the defendant's bed and his pillow).


      2
       The Honorable Thomas D. Thalken, United States Magistrate Judge for the
District of Nebraska.

                                          -4-
       B.    Sentencing Issues
       "The correct application of the guidelines is a question of law subject to de
novo review," while a "factual determination of the sentencing court is reviewed
under a clearly erroneous standard." United States v. Collins, 

, 144 (8th
Cir. 1997).

             1.   Quantity of Methamphetamine
       Tirado argues the district court erred in calculating the amount of
methamphetamine used to sentence him. First, Tirado asserts the 128 grams of
methamphetamine were found in his residence during an unreasonable search and
should be excluded from the sentencing calculation. Because Tirado’s Fourth
Amendment rights were not violated by the search of his residence, this argument
fails.

       Second, Tirado notes the jury found him guilty of the lesser included offense
of possession of methamphetamine rather than possession with intent to distribute,
and argues use of the acquitted conduct for sentencing is unreasonable and
irresponsible. The district court found all 227.77 grams of methamphetamine were
attributed to Tirado as relevant conduct to the conspiracy count. Even if the 128
grams found in Tirado’s residence were attributable to the acquitted conduct of Count
II, the district court still would not have erred in using that evidence to sentence
Tirado. This Circuit allows acquitted conduct to be used for sentencing purposes if
proved by a preponderance of the evidence, especially when a conspiracy charge is
included. United States v. Woods, 

, 730 (8th Cir. 2001); United States
v. Madrid, 

, 763 (8th Cir. 2000) (inclusion of related drugs was
reasonably foreseeable for participant in conspiracy). Therefore, whether or not the
district court used acquitted conduct to sentence Tirado, the district court properly
calculated the amount of methamphetamine attributable to Tirado.




                                         -5-
              2.     Obstruction of Justice Enhancement
       The Sentencing Guidelines allow a two-level obstruction of justice
enhancement. U.S.S.G. § 3C1.1 (2001). Qualifying conduct includes "threatening,
intimidating, or otherwise unlawfully influencing a co-defendant, witness, or juror,
directly or indirectly, or attempting to do so." 

       Tirado argues "there is inadequate evidence to show that Tirado knew that an
investigation was underway" when he confronted the informant on August 24, 2000.
Tirado argues the evidence, at best, "shows that Tirado was attempting to find out if
an investigation was underway." Tirado concedes the evidence comes close to
suggesting Tirado knew of an impending investigation, but argues the evidence fails
to establish Tirado actually knew the investigation was underway.

       Our Court was confronted with a similar case in United States v. Watts, 

, 333 (8th Cir. 1991), where the defendant was riding in a car when he
purchased cocaine. When an unmarked vehicle following the defendant's car began
flashing its headlights, the defendant threw the cocaine out the window. The
defendant argued the district court erred in enhancing his sentence for obstruction of
justice because he did not know he was under investigation when he threw the
cocaine. We rejected that argument, believing "it is reasonable to infer [the
defendant] thought he was being followed by law enforcement authorities, thought
his arrest was imminent, and attempted to get rid of evidence." 

v. United States, 

, 536 (8th Cir. 1999), the sentencing
evidence established the defendant opened a confidential informant's shirt as if
looking for a wire and told the informant there would be “hell to pay” from his
“brothers” if anything were to happen to him. On two other occasions, the defendant
warned the informant “there would be some people getting even,” if anything
happened to him, and “there would be hell to pay” if the informant was working for
the government. 

court used this evidence for an obstruction of justice

                                         -6-
enhancement and we affirmed, believing "the nature and frequency" of the
defendant's threats justified the obstruction of justice enhancement. 

the defendant in Brown also argued "he did not have actual
knowledge of an ongoing criminal investigation," so he could not have obstructed
justice. 

observed that willful obstruction of justice "should be reserved
for the more serious case, where misconduct occurs with knowledge of an
investigation, or at least with a correct belief that an investigation is probably
underway." 

States v. Oppedahl, 

, 586 (8th Cir.
1993)). We affirmed the district court's finding that the defendant "held the belief
that an investigation was probably underway," because a reasonable inference from
the defendant's actions was he believed an investigation was "probably underway."

on United States v. Oppedahl, where the defendant told a major
LSD customer that he would kill him if he ever "narked" on the defendant's supplier.

. The statement was made while both were under suspicion
and during the course of an investigation, but neither were cooperating with law
enforcement. After the defendant was arrested and convicted of conspiracy to
distribute and possession with intent to distribute LSD, the probation officer
recommended a two-level enhancement for obstruction of justice for the comments
made to the drug customer. The district court rejected the recommended
enhancement and the Circuit affirmed "the ruling below that declines to apply the
two-level enhancement for obstruction of justice where the defendant was unaware
of the investigation when he made the culpable threat." 

      Factually, Tirado’s case fits somewhere between Watts/Brown and Oppedahl.
As in each of those cases, this court will not reverse the district court's factual
determination, here finding Tirado believed an investigation was probably underway,
because the determination was not clearly erroneous.

                                         -7-
       Tirado lifted up his shirt and appeared to try to get the informant to lift his
shirt. It is reasonable to infer Tirado was looking for a wire, which would lead to the
reasonable inference Tirado believed an investigation was "probably underway."
Tirado then chased the informant on foot and with his Blazer. Because Tirado had
a correct belief that an investigation was underway and threatened and intimidated the
informant, the district court correctly applied the two-level obstruction of justice
enhancement.

III.   CONCLUSION
       For the reasons discussed above, the district court is affirmed in all respects.
