LINCOLN, Neb. (AP) — A Lincoln man has pleaded guilty to manslaughter in connection with a fatal car crash last year.

19-year-old Cristofer Cazun entered guilty pleas to two manslaughter charges Monday.

Cazun was driving a vehicle last September when he rear-ended a pickup. A passenger in the second vehicle, 50-year-old Randall Woita, died at the scene. Two others in that car were also injured.

Authorities say Cazun was high on synthetic marijuana at the time and was speeding prior to the crash.

Cazun is scheduled to be sentenced on Sept. 3.
