LINCOLN, Neb. (AP) — Authorities have released the name of a motorcyclist who plunged to his death from an overpass in Lincoln.

The accident occurred about 5 p.m. Tuesday when something caused the motorcyclist to hit a concrete barrier on Rosa Parks Way and fall from his bike to a parking lot below.

He was identified as 19-year-old Mark Wenzl, of Seward.

Investigators had thought another vehicle may have been involved but have ruled that out as a possible cause of the crash.
