Before WOLLMAN, FAGG, and MELLOY, Circuit Judges.
                          ___________

PER CURIAM.

       After a trooper stopped a car for speeding and found cocaine inside, the
Government charged the car’s owner and passenger, Robert Rydell Williams, with
conspiracy to distribute cocaine and attempted distribution of cocaine. Williams filed
a motion to suppress the drugs asserting the traffic stop was the product of racial
profiling and violated his Fourteenth Amendment rights. Following three evidentiary
hearings, a magistrate judge recommended that Williams’s motion to suppress be
granted. The district court* disagreed, holding that even if the trooper engaged in

       The Honorable James M. Rosenbaum, Chief Judge, United States District
Court for the District of Minnesota.
racial profiling as the magistrate concluded, there was no basis to suppress the cocaine
because Williams voluntarily consented to the search resulting in the cocaine’s
seizure, purging any taint that may have infected the original stop. Accordingly, the
district court denied Williams’s motion to suppress. A jury convicted Williams.
Williams now appeals the denial of his suppression motion. We affirm.

        A trooper stopped Williams’s car for speeding. During routine questioning of
the driver and Williams, the trooper became suspicious based on their contradictory
and vague answers about their trip. Nevertheless, the trooper gave the driver a
warning ticket, returned her license and registration, and told her “to watch her speed
and have a safe trip.” The trooper then asked the driver whether he could ask her a
few more questions and search the vehicle, and she agreed. After informing Williams
he was not required to consent to a search, the trooper also obtained Williams’s verbal
and written consent. During the search, the trooper found some detergent boxes in the
back of the vehicle that had been opened and resealed. About a half an hour after the
initial stop, the trooper asked Williams whether he could open the boxes, and
Williams agreed. Inside the boxes, the trooper found about five kilograms of cocaine.
Williams was arrested and acknowledged the cocaine belonged to him.

       A traffic stop is constitutional, regardless of the officer’s subjective intent, if
the officer had probable cause to believe a traffic violation occurred. United States
v. Gomez-Serena, 

, 1041 (8th Cir. 2004) (defendant who conceded
officer had probable cause to conduct traffic stop failed to show officer stopped him
solely on account of race) (citing Whren v. United States, 

(1996)). A
trooper who sees a traffic violation has probable cause to stop the vehicle and conduct
a reasonable investigation. United States v. Sanchez, 

, 974 (8th Cir.
2005). A reasonable investigation includes requesting asking the driver and
passengers about their destination, route, and purpose. 

If an encounter
after a traffic stop’s completion is consensual, then an officer may ask questions



                                           -2-
unrelated to the stop and request consent to search the vehicle. United States v.
Santos-Garcia, 

, 1078 (8th Cir. 2002).

       Here, the district court found the officer had a reasonable and articulable
suspicion that a traffic violation occurred. This finding is not clearly erroneous.
Thus, the initial stop was not unconstitutional as Williams contends. 

. Further, even if it was, any taint of illegality was purged by
Williams’s voluntary consent to search. See United States v. Moreno, 

,
900 (8th Cir. 2002). The district court carefully analyzed the factors impacting the
voluntariness of Williams’s consent. See 

court noted the temporal
proximity between the alleged illegality and the consent weighed in favor of finding
Williams’s consent was an act of free will because at least a half an hour elapsed by
the time the officer reconfirmed William’s consent to search the boxes of laundry
detergent. Second, the court concluded that intervening factors confirmed Williams’s
consent was voluntary. Williams signed a consent form advising him of his right to
refuse consent, and Williams studied the form carefully before signing it. Further,
Williams was not in custody or being detained when he consented. The officer had
already issued the warning ticket and told the driver she was free to leave. Last, the
court stated the lack of purposefulness or flagrancy of the officer’s alleged misconduct
weighed in favor of a finding of voluntariness. There was no evidence the officer
stopped the car as part of a preconceived plan to obtain consent to search it, and the
officer’s misidentification of the driver as white on the warning form was irrelevant
to the voluntariness of Williams’s consent because the driver and Williams did not
know a race-identifying box had been mismarked on the warning form. Having
carefully reviewed the record, we agree with the district court’s analysis and conclude
the court’s findings that Williams consented is not clearly erroneous. 

the district court committed clear error in finding he did not
withdraw his consent. Because the record supports the finding, it is not clearly
erroneous. United States v. Gray, 

, 1026 (8th Cir. 2004). At the first

                                          -3-
hearing, the trooper testified he obtained Williams’s written consent to search the
vehicle and reconfirmed his consent before searching the detergent boxes. Williams
did not contest this testimony in any way. Months later, Williams argued he withdrew
his consent, and on cross-examination, his witnesses admitted they never mentioned
this claim when they were interviewed immediately after their arrest. In any event,
an officer who arrived on the scene as the trooper searched the detergent boxes
testified he heard the trooper ask Williams whether he could search the boxes and
Williams told the trooper he could. The district court credited this testimony.

       Williams last contends the racial profiling in this case was so outrageous that
the district court should have dismissed the indictment. We disagree. As the district
court stated, there is strong evidence to suggest racial profiling could not have been
a motive for the traffic stop because the trooper could not see the race of the car’s
occupants. In any event, there is no evidence of outrageous conduct that shocks the
conscience of the court, necessary to establish a due process violation. See United
States v. King, 

, 867-68 (8th Cir. 2003). And, even if there was a due
process violation, it is uncertain that dismissal is an appropriate remedy. See United
States v. Armstrong, 

, 461 n.2 (1996) (Court has not decided whether
dismissal of indictment or other sanction is proper remedy if defendant has been
victim of prosecution based on race); United States v. Chavez, 

, 486-87
(5th Cir. 2002) (Supreme Court has not ruled there is a suppression remedy for
violations of Fourteenth Amendment’s Equal Protection Clause).

      We have considered the arguments in Williams’s pro se brief and reject them
all. We thus affirm the denial of Williams’s motion to suppress.
