IRONTON -- The case involving the death and unexplained dragging of Guy Cameron Thomas for 10 blocks under an Ironton police cruiser in the snow will be presented to an upcoming session of the Lawrence County grand jury, Prosecutor J.B. Collier Jr. said Monday.

Thomas, 46, of 914 S. 9th St., Ironton, was found dead March 8 beneath a police cruiser outside the Ironton Police Department. His body had been dragged about 10 blocks beneath the cruiser on a snowy and icy night.

On Monday, the Ohio Bureau of Criminal Identification and Investigations turned over a file in the case to the prosecutor's office.

A preliminary autopsy report from the Franklin County Coroner's office showed Thomas died from asphyxiation and that his chest was crushed and several ribs broken, Collier said.

County Coroner Burton Payne said it isn't known whether the ribs were fractured before or after Thomas died.

"There was no evidence of an impact injury," Payne said.

Some findings could be consistent with a seizure, he said.

An Ohio Highway Patrol report showed Thomas had been lying on South 9th Street when his body became lodged under the cruiser.
