documents on board one of the buses. The agent permitted him to retrieve a small bag containing these items. The agent also testified that, upon checking the items in the bag, he found $4000 in cash and some receipts that Hernandez indicated were for repairs and painting recently done on the vehicles. The agent further testified that, when he later inventoried the items in the bag, the receipts were no longer there.
Another agent testified that Hernandez told him that an individual named “Elias” had rented the buses to pick up the group, but that Hernandez was unable to tell the agent Elias’s last name or how to reach him even though Hernandez had allegedly known Elias for six years. One of the agents made a phone call to the Las Cruces Holiday Inn, where Hernandez had said the Folklórico group was staying, and was informed no such group had registered. The agents therefore intensified their search of the buses.
In searching the buses, agents found panels that they surmised had been worked on recently due to the presence of fresh putty. Upon drilling through the panels in each bus, the agents found marijuana in a hidden compartment. They also found that tanks had been installed inside the diesel fuel tanks of the two buses and these tanks contained marijuana. A search of both buses also yielded bags of gray putty, a package of rivets, and a cordless drill with screw bits.
The government also called as a witness W.D. Russell, who was a service center manager for Greyhound Bus Lines and had been a bus mechanic for 30 years. Russell testified that he had examined the two buses on the weekend before the trial, and that based on the condition of the radiators, tires, and fuel systems, his opinion was that the buses could not have been driven from Guadalajara to El Paso without stopping for additional fuel.
The trial court denied Hernandez’s motion for judgment of acquittal but granted the motions made by the four codefend-ants. The jury convicted Hernandez on all five counts of the indictment, and the court sentenced him to serve ten years on each of four of the counts and five years on the Travel Act count, all to run concurrently, a special parole term of eight years on the substantive marijuana counts, and a $250 fine.
II.
In evaluating the sufficiency of the evidence on appeal, the reviewing court must consider the evidence in the light most favorable to the government, giving the government the benefit of all reasonable inferences and credibility choices.1 The standard is whether any rational trier of fact could have found the essential elements of the crime beyond a reasonable doubt.2
а. Conspiracy to import and conspiracy to possess
In a drug conspiracy prosecution under 21 U.S.C. §§ 846 and 963, the government must prove beyond a reasonable doubt that a conspiracy existed, the accused knew of the conspiracy, and he knowingly and voluntarily joined it.3 No evidence of overt conduct is required.4 A conspiracy agreement may be tacit, and the trier of fact may infer agreement from circumstantial evidence.5 This court, however, will not lightly infer a defendant’s knowledge of and acquiescence in a conspiracy.6 Although all of a defendant’s alleged coconspirators are acquitted, the
