BLOOMINGTON (AP) — A 24-year-old Chatsworth man who died in an all-terrain vehicle accident was pinned under the overturned ATV.

McLean County Coroner Beth Kimmerling says Lucas Stork appears to have died because he couldn't breathe when he became trapped under the vehicle. Stork and three others were riding the ATV when it crashed late Saturday in rural Arrowsmith, about 20 miles east of Bloomington.

Kimmerling says speed didn't play a factor in the crash. She says an autopsy Monday showed Stork didn't suffer any fatal traumatic injuries in the crash. A final cause of death will be determined after toxicology tests are done.
