Before Trooper Bigsby had completed the traffic stop, another officer, Jason Brownell, stopped to ask if Bigsby needed any assistance. When Trooper Bigsby found out that Trooper Brownell had some Spanish-speaking ability, Bigsby asked if Brownell would stay and assist. Trooper Bigsby testified that with Brownell's assistance, he completed a warning citation and returned Gonzalez's license and paperwork. Having learned through his dispatcher that Gonzalez had been arrested in 2003 for driving while intoxicated, Bigsby then asked, through Trooper Brownell, if he could "ask a few more questions," and Gonzalez answered yes. Again through Trooper Brownell, Bigsby asked if Gonzalez had ever been arrested for driving while intoxicated, and Gonzalez answered that he had. Bigsby and Brownell also inquired whether any alcohol, guns, marijuana, methamphetamine, heroin, or large amounts of cash were in the car, and Gonzalez answered no. Brownell then asked for and received consent to search the car. Trooper Bigsby went directly to the rear passenger side of the vehicle and opened a cooler that was in the back seat, where he found a large plastic bag that contained seven bundles wrapped in rubber bands inside aluminum foil packaging. These bundles contained a total of $124,700 in currency. Gonzalez and the vehicle were then taken to the Nebraska State Patrol office in Lincoln.
