OKLAHOMA CITY (AP) — The Oklahoma County Sheriff's Office says it's investigating the death of a county jail inmate.

The sheriff's office says in a Tuesday news release that 56-year-old Daryl Clinton died Saturday at a hospital where he was taken after being found unresponsive earlier in the day.

Clinton was arrested following an Aug. 6 auto crash on a warrant for possession of controlled drugs with intent to deliver.

Court records show he was being held on a probable cause warrant, but do not list formal charges against him.

The sheriff's office says its special investigations unit is investigating the death. A suspected cause of death has not been released.
