LINCOLN, Neb. (AP) — Authorities say a Nebraska leader has been killed in a hit-and-run near his Hickman home.

The Lancaster County Sheriff’s Office says 62-year-old Gregory Nicklas was killed Thursday night as he walked his dog.

Nicklas’ wife found her husband badly injured near the end of their driveway. He died at the scene.

Sheriff Terry Wagner said authorities need help from the public to find a suspect or suspects in the case.

Nicklas was the co-founder and co-CEO of Christian Heritage, a group that cares for abused and neglected children in the state.
