Jоse Mendoza-Gonzalez was convicted by a jury of conspiracy to distribute methamphetamine and marijuana, possession of methamphetamine with intent to distribute, and possession of marijuana with intent to distribute. The district court 1 sen *791 tenced Mendoza-Gonzalez to 235 months imprisonment, and he appeals. 2 We affirm.
On February 5, 2002 Mendoza-Gonzalez was driving his semitractor in Iowa on eastbound Interstate 80 when he came to the Dallas County weigh station for trucks. He pulled into the station where Officer Kenneth Burke was on duty. Officer Burke is an Iowa Department of Transportation officer, and he noticed that the truck was not displaying the required DOT and ICC numbers or Iowa fuel tax sticker. He approached the truck and asked Mendoza-Gonzalez to bring his logbook, permits, and other paperwork into the weigh station office. Examination of the logbook revealed that Mendoza-Gonzalez had failed to retаin the previous seven days of the log as required under 49 C.F.R. § 395.8. He was also unable to produce an Iowa trip permit.
Officer Burke decided to conduct a North American Standard Level II inspection of Mendoza-Gonzalez and his truck. See Commercial Vehicle Safety Alliance, Truck Inspection Program, North American Standard Level II WaUo-Around Driver/Vehicle Inspection Procedure (2004), available at http://www.cvsa.org/programs/inspec-tion_levels.html; see also 49 C.F.R. § 350.105. Burke has been certified by the Federal Motor Carrier Safety Administration to perform inspections, and he later testified that there are three levels of inspection to which trucks are routinely subjected at weigh stations. A level III Driver/Credential Inspection involves examination of the paperwork associated with the truck, the driver’s license, registration, logbook, and permits. A Level II Walk-Around Driver/Vehicle Inspection is inclusive of the Level III inspection, but -the officer also inspects all safety equipment that can be examined without physically getting under the vehicle, such as lights, tires, emergency equipment, and safety belts. A Level I North American Standard inspection is inclusive of the Level II and III inspections, but also includes an examination of equipment that can only be checked from underneath the truck, such as the brake cables and exhaust system. Officer Burke testified at the suppression hearing that officers at weigh stations generally perform a Level I or Level II inspectiоn unless extremely inclement weather makes only a Level III inspection of the driver and paperwork practical. The weather conditions were not extreme at the time Mendoza-Gonzalez’s truck was inspected.
Officer Burke testified that as he walked with Mendoza-Gonzalez from the weigh station back to the truck to perform the Level II inspection, he asked him whether there was anyone else in the truck or any prohibited items, such as weapons, narcotics, alcohol, or radar detectors. Mendoza-Gonzalez replied that his brother was inside but that there were none of the items Burke had mentioned. Burke testified that he routinely requests a driver’s consent to search his truck because consent permits an officer to go beyond the standard inspection and to look inside the driver’s personal belongings for illegal items such as radar detectors or weapons. Hе testified that he asked whether Mendoza-Gonzalez would mind if he searched the truck. Mendoza-Gonzalez responded “yes” and “I have nothing to hide.” Mendoza-Gonzalez testified differently. He said Officer Burke never asked if he could search the truck and that he specifically told Burke not to enter the cab because his *792 brother was resting in the sleeper berth. Officer Burke testified that after their conversation Mendoza-Gonzalez summoned his brother оut of the truck, and he commenced the inspection.
Officer Burke testified that immediately upon entering the truck he detected strong odors of marijuana and dryer sheets. In his prior position with the Madison County Sheriff Department where he worked in drug interdiction, Burke had learned that dryer sheets were frequently used by drug traffickers to mask the smell of marijuana. Because of the odors in the truck, he suspected that it either currently or recently contained marijuana. Proceeding with the Level II inspection, Officer Burke checked the sleeper area to make sure that it contained a mattress, bed linens, safety equipment, and occupant restraints as required by 49 C.F.R. § 893.76. Upon initial inspection he was unable to see any occupant restraint on top of the mattress. He lifted the mattress to see if the restraint was underneath, but he still could not find it. Burke testified that in his experience restraints sometimes slip down into the storage box under the mattress. He lifted the lid of the box to look for the restraints and saw a package about the size of a shoe box, wrapped in what appeared to be dryer sheets and clear cellophane. Officer Burke testified that based upon his training and experience he believed that the package contained marijuana.
Officer Burke took Mendoza-Gonzalez and his brother into the weigh statiоn building. He explained to them that he had seen a suspicious package during his inspection and that he was going to investigate further. He did not arrest the brothers at that time, but he placed them both in handcuffs and returned to the truck. At this point no one had advised them of their rights under
Miranda v. Arizona,
When Officer Burke returned to the truck he found that the cab now smelled much more strongly of marijuana. He reopened the storage compartment under the mattress and noticed what appeared to be black plastic bags lining the area under the package he had seen earlier. He pullеd the bags aside and saw that there were 15 to 20 packages similar to the first one. Suspecting that the packages contained marijuana, Burke placed Mendoza-Gonzalez and his brother under arrest and contacted the Iowa Division of Narcotics Enforcement. A total of nineteen packages were in the truck. They contained 122.619 kilograms of marijuana and 445.2 grams of 57% pure methamphetamine. The packages were examined for latent fingerprints, and the wrappings were found to contain a palm print matching that of Mendoza-Gonzalez, along with prints of several unknown persons.
Several witnesses testified against Mendoza-Gonzalez at trial. His brother testified that he had first learned about the *793 drugs when Mendoza-Gonzalez told him at the weigh station that there were 300 pounds of marijuana and six pounds of “crystal” in the truck. 5 A jailhouse informant, Ricky Carmichael, testified that Mendoza-Gоnzalez had told him that he had been taking 335 pounds of marijuana and two pounds of methamphetamine from California to Minnesota when he was arrested. Mendoza-Gonzalez had also said that the drugs were wrapped in plastic and dryer sheets and were hidden under the sleeper berth in the truck. According to Carmichael, Mendoza-Gonzalez stated that he was unconcerned about fingerprints, because he believed the drugs were wrappеd too tightly in plastic to contain any usable prints. The jury also heard Mendoza-Gonzalez’s incriminating statement in the weigh station that he was “going to jail.”
Mendoza-Gonzalez was found guilty of all charges presented to the jury. At sentencing the court found Mendoza-Gonzalez responsible for 122.169 kilograms of marijuana and 253.77 grams of actual methamphetamine with a marijuana equivalency of 5075.4 kilograms. A total marijuana equivalency of 5198 kilograms was attributed to Mеndoza-Gonzalez, and this led to a base offense level of 34 under U.S.S.G. § 2D1.1 (2002). The district court applied a two level enhancement for obstruction of justice pursuant to U.S.S.G. § 3C1.1, after finding that Mendoza-Gonzalez had committed perjury at his suppression hearing. His illegal reentry conviction was disregarded for purposes of sentencing because the total offense level for that charge was more than nine levels lower than his total offense level for the drug charges. See U.S.S.G. § 3D1.4. His total offense level of 36, combined with his Criminal History Category of III, produced a sentencing range of 235 to 293 months. The district court sentenced Mendoza-Gonzalez at the low end of the range to 235 months.
Mendoza-Gonzalez claims that the district court erred by not suppressing the evidence found in the truck and his statement that he was “going to jail.” He also argues that there was insufficient evidence to sustain his convictions for conspiracy and for possession with intent to distribute and that the district court erred by imposing an enhancement for obstruction of justice. 6 We address each argument in turn.
Mendoza-Gonzalez claims that his Fourth Amendment rights were violated by the inspection of the compartment under the sleeper mattress in his truck. We review the district court’s findings of fact for clear error and its denial of a motion to suppress de novo.
United States v. Payne,
In
New York v. Burger,
One requirement for a Level II inspection is that the officer inspect all safety belts. See North American Standard Level II Walk-Around Driver/Vehicle Inspection Procedure, supra. Federal regulations require that there be safety belts to restrain occupants of the sleeper berth. See 49 C.F.R. § 393.76. Judge Pratt found credible Officer Burke’s testimony that he was unable to see the required safety belts on top of the mattress or directly underneath it. The court heard and accepted Burke’s testimony that, in his experience, safety belts sometimes fall into the storage compartments beneath the mattress and that he opened the compartment to look for the restraints as part of the standard Level II inspection. The district court rejected as not credible Mendoza-Gonzalez’s contrary testimony that the layout of the sleeper berth made it impossible for the occupant restraints to fall into the storage сompartments. The court commented that Mendoza-Gonzalez appeared to be “making it up as he went along.”
The district court is in the best position to judge the credibility of witnesses who testify before it,
United States v. Newson,
The district court also found that Mendoza-Gonzalez had voluntarily consented to the search of his truck. It found credible Officer Burke’s tеstimony that Mendoza-Gonzalez said “yes” and that he had “nothing to hide” when asked whether he would mind if Burke searched the truck, and it specifically rejected Mendoza-Gonzalez’s contrary testimony as not credible. The court considered the relevant factors identified in
United States v. Chaidez,
In sum, we hold that Officer Burke did not violate Mendoza-Gonzalez’s Fourth Amendment rights by opening the storage compartment under the sleeper berth in which he found large quantities of illegal drugs. He was entitled to inspect the compartment for occupant restraints during his Level II inspection, and we also see no error in the district court’s finding that Mendoza-Gonzalez voluntarily consented to a search of his truck. We conсlude that the district court did not err in denying the motion to suppress.
Mendoza-Gonzalez also contends that his statement to Officer Caudle that he was “going to jail” should have been suppressed. As noted above, we review the district court’s factual findings for clear error and its denial of a motion to suppress de novo.
Payne,
Interrogation includes not only express questioning by law enforcement officers, but also words or actions that officers should know are reasonably likely to elicit an incriminating response from a suspect.
Rhode Island v. Innis,
Mendoza-Gonzalez asserts that there was insufficient evidence for the jury to convict him of possession of marijuana and methamphetamine with intent to distribute or of conspiracy to distribute methamphetamine and marijuana. In reviewing the sufficiency of the evidence on appeal, the court views the evidence in the light most favorable to the government, resolving evidentiary conflicts in favor of the government, and accepting all reasonable inferences drawn from the evidence that support the jury’s verdict.
United States v. Espino,
Ample evidence was presented from which a reasonable jury could infer that Mendoza-Gonzalez possessed the drugs with the intent to distribute mari
*796
juana and methamphetamine. In order to prove possession with intent to distribute, the government must prove that the defendant had knowing possession of the drugs and the intent to distribute them. The element of knоwing possession is satisfied by proof of constructive possession which requires ownership, dominion, or control over the contraband or dominion over the premises in which it is concealed.
United States v. Sanchez,
There was also sufficient evidence for a reasonable jury to conclude that Mendoza-Gonzalez conspired with others to distribute marijuana and methamphetamine. Our cases have sustained conspiracy convictions when all conspirators other than the defendant were unknown so long as the government has produced evidence supporting a reasonable inference of conspiracy.
See United States v. Nelson,
Mendoza-Gonzalez next сontends that the district court erred in applying a two level sentencing enhancement for obstruction of justice pursuant to U.S.S.G. § 3C1.1. We review a district court’s factual findings underlying an obstruction of justice enhancement for clear error and its construction and application of the guidelines de novo.
United States v. Esparza,
Here, Chief Judge Longstaff examined the transcripts of the suppression hearing in light of the evidence he personally heard at the trial and found that Mendoza-Gonzalez willfully gave false testimony concerning material matters in the case. *797 Mendozа-Gonzalez testified at the suppression hearing that his truck displayed the required DOT and ICC numbers. The district court found that this was false based on photographs of the truck which showed these numbers were nowhere to be seen. Mendoza-Gonzalez also testified at the suppression hearing that a screen or net restrained passengers in the sleeper berth, but the district court found that this was false based on Officer Burke’s credible testimony and on photographs of the sleeper berth. Mendoza-Gonzalez testified that he never consented to the search of the truck, but Judge Pratt specifically found that Officer Burke’s contrary testimony was credible. Mendoza-Gonzalez testified that he had no knowledge of the 122 kilograms of marijuana found in his truck, but the district court found this false based on the presence of his palm print on the packaging and the testimony of two witnesses. There was no clear error in the district court’s finding that Mendoza-Gonzalez perjured himself, and the obstruction of justice enhancement was appropriate.
Accordingly, we affirm the judgment of the district court and dismiss as premature the ineffective assistance of counsel claim.
Notes
. The Honorable Ronald E. Longstaff, Chief Judge for the United States District Court for the Southern District of Iowa.
. Mendoza-Gonzalez also was convicted by a plea of guilty to one count of illegal reеntry which is not involved in his appeal (he reentered the country after having been deported following a robbery conviction).
. The Honorable Robert W. Pratt, United States District Judge for the Southern District of Iowa, conducted the suppression hearing and ruled on the motion to suppress.
. Following Mendoza-Gonzalez's statement that he was "going to jail,” Officer Caudle asked, "You are going to jail? Then you know what’s out in the truck?” Mendoza-Gonzalez replied, "250.” Officer Caudle then asked, "250 marijuana?” Mendoza-Gonzalez replied, "250 pounds of marijuana.”
. Officers testified at trial that the highly pure methamphetamine seized from the truck would likely be diluted with a cutting agent to produce more than five pounds of methamphetamine for distribution.
. Mendoza-Gonzalez also claims that he did not receive effective assistance of counsel at trial. Such claims should generally be raised in collateral proceedings rather than on direct appeal because they typically involve facts outside the record.
United States v. Woods,
. Because of these determinations it is not necessary to consider the district court's alternate holding that Officer Burke had probable cause to search the truck and that the automobile exception to the warrant requirement also applied.
