HIBBING, Minn. (AP) — Authorities are investigating the suicide of an inmate at the St. Louis County jail in Hibbing.

A news release from the sheriff’s office says 30-year-old Shane Ervin Fischer, of Duluth, was booked around 2:15 a.m. Sunday on suspicion of drunken driving, fleeing in a motor vehicle and assault for attempting to disarm a state trooper. He was found about 7 a.m. It says the preliminary investigation indicates he attempted suicide minutes after staff did a required, routine check on his well-being.
