A man was found dead following an overnight crash in Crawford County, according to Pennsylvania State Police.

It happened as David Miller, 59, of Saegertown, was driving a fabricated three-wheeled motorcycle east in the 17200 block of State Highway 198 in Hayfield Township, investigators said.

He drove off the left side of road into a ditch, flipped the vehicle and was killed instantly, according to troopers.

State police said there were not any witnesses, and Miller was discovered in a field just before 7 a.m. Saturday.

The motorcycle was cool to the touch with overnight condensation, according to investigators.
