Nebraska State Patrol troopers arrested a man after they found a variety of controlled substances in his car following a traffic stop on Interstate 80 near Kearney. The patrol said they spotted a westbound 2017 Nissan Altima speeding on I-80 about 5 p.m. Tuesday. The trooper determined that the 40-year-old driver’s license had been suspended, and the man was arrested. A search of the car uncovered 617 vials of ketamine, an anesthestic, which weighed 41 pounds. The estimated street value of the ketamine was $617,000, the patrol said. Troopers also found 3.5 grams of marijuana, one gram of methamphetamine, a gram of what they think was cocaine and unmarked tablets. According to the National Institute on Drug Abuse, ketamine is used as a “club drug” by young adults at bars, nightclubs, concerts and parties.
