A 27-year-old Marengo man was killed in a one-vehicle crash on State Route 61 in Delaware County Wednesday night.

Jason M. Boehnlein, 27, was driving a 2008 Ford Fusion south on State Route 61, just north of State Route 521, when he apparently drove off the right side of the road, struck a ditch, a parked 2000 Ford F-350 and overturned while striking a mailbox and a sign, state troopers said.

The crash occurred at 11:38 p.m. Wednesday.

Boehnlein was pronounced dead at the scene.

Alcohol is believed to be a factor in the crash, troopers said. Boehnlein was not wearing his seatbelt.

The crash remains under investigation.

The Ford F-350 was parked and unoccupied in a private drive.

Assisting state troopers were the Delaware County Sheriff’s Office, the Porter Kingston Fire Department and Delaware County EMS.
