GOSHEN, Ind. -

Goshen Indiana Conservation Officers are searching for a semi they say was involved in an accident with an ATV Friday night.

Officers say around 9:25 p.m. last night 36-year-old Marty Clawson of Goshen was pushing his ATV on foot at the intersection of Lafayette and Main Street when he saw a semi approaching southbound on Main Street.

Clawson told police the semi was driving around 30 mph and was very close to the edge of the road. Clawson says he tried to pull the ATV out of the path of the semi, but it struck his ATV, which threw Clawson against the trailer.

The semi continued on and did not stop, according to police.

A passerby found Clawson lying in the road and called 911. He received serious back injuries, including nine fractured vertebrae.

Officers are asking for the public's help in identifying the semi that was involved in the accident. It is described as a 1990s, dark colored tractor with multiple amber marker lights on the cab pulling a light colored box trailer.

The trailer of the semi may have also been damaged in the right rear area.

Indiana Conservation Officers have obtained a photograph of the possible semi involved in the accident from the surveillance footage at a nearby Seven Eleven convenience store shortly after the accident. The semi is believed to be a Peterbilt with a sleeper cab.

Investigating officers say the driver may not have known the accident occurred and is not considered a suspect for any criminal charges at this time.

The victim viewed the photograph and advised investigating officers that he is confident this is the involved semi.

Anyone with information is asked to contact the Goshen City Police Department or the Indiana Conservation Officers dispatch center at 1-812-837-9536.
