Indiana State Police are investigating the death of an Edinburgh man, who suffered a fatal seizure after a rollover crash on Interstate 65 in Shelby County early this morning.

29-year-old Devin Streeval of Edinburgh died after at first appearing conscious, alert and refusing treatment by medics.

State police say they and the Shelby County Sheriff’s Department were called to the accident scene at about 1:10 a.m. on the interstate near the State Road 252 exit. An SUV had crashed and rolled over, but Streeval, a passenger, was standing outside the vehicle and the woman driver was seated in the driver’s seat. Both appeared injured but alert and told police that they did not want an ambulance.

The Shelbyville Fire Department and the Flat Rock Volunteer Fire Department were already on their way and when they arrived, the victims were taken to the back of the ambulance to be checked out.

Both the driver, 28-year-old Alyssa Caudill of Columbus, and the passenger, Devin Streeval, continued to insist that they did not need treatment, when  Streeval began having a seizure. He was taken to IU Methodist Hospital in Indianapolis but died at about 3:15 a.m. at the hospital.

State police say the investigation is ongoing and an autopsy is scheduled for tomorrow by the Marion County Coroner’s Office.
