NEW PHILADELPHIA -- An autopsy has been ordered for a Zanesville man pronounced dead at Union Hospital in Dover Wednesday night (March 2) after being found slumped over in the tractor-trailer he was driving on Interstate 77.

Garey Spung, 61, was transported by ambulance to Union Hospital, where he was pronounced dead.

Motorists reportedly administered CPR at the scene in Tuscarawas County until emergency medical personnel arrived.

The autopsy will reportedly be conducted at the Stark County Coroner's Office.

According to an Ohio State Highway Patrol trooper assigned to the New Philadelphia post, Spung had not suffered any visible injuries or trauma at the time of his death.

The trooper also noted that Spung's truck, which was jackknifed blocking both southbound lanes of I-77 at mile post 75, was not damaged.

According to the trooper, motorists reported finding the tractor-trailer just after 10 p.m., advising Spung was slumped over and unresponsive inside the tractor.

He was removed from the truck by the motorists who performed CPR.

Troopers reported Spung apparently stopped the truck, possibly as he felt the onset of a medical condition, and then attempted to back the truck off the interstate, at which time it jackknifed.

The truck's parking brake was set, according to troopers.
