CHADRON, Neb. (AP) — Authorities are investigating the death of a Dawes County man whose body was found under his tractor mower.

The body of 68-year-old Dave Gilmore was found around 9 p.m. Monday on his property near Chadron State Park. County Attorney Vance Haug said Tuesday that a preliminary investigation shows the death was accidental. But Haug also says Gilmore had health issues that could have been involved in his death.

An autopsy was ordered.
