LINCOLN, Neb. (AP) — A man was sentenced in Lincoln to up to three years in prison following a traffic stop that turned up more than $400,000 last year.

30-year-old Jairo Cardenas entered a plea agreement to possession of money during a drug violation. He was sentenced Tuesday to serve at least 18 months before becoming eligible for parole.

Court records say Cardenas was stopped in March 2014 along Interstate 80 for following too closely. The Lancaster County Sheriff’s Office requested to search the vehicle, during which a police dog alerted deputies to the odor of drugs. Deputies then found $409,748 hidden under the passenger seat.

An attorney for Cardenas called the sentence “a little severe,” saying the vehicle that was searched didn’t belong to his client.
