CAMBRIDGE, Neb. (AP) – Authorities say a Nebraska Game and Parks worker has died in a mower accident.

The Frontier County Sheriff’s Office says the accident occurred around noon Tuesday while the 68-year-old seasonal employee was mowing campgrounds at Harry Strunk Lake near Cambridge. The office says the mower fell down a 10-foot drop-off and landed atop the man, pinning him in water.

Another worker found him and began resuscitation attempts. The man was pronounced dead later at a Cambridge hospital.

The Sheriff’s Office identified the man as Dale Oberst.
