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.

Emergency personnel could not revive him. The sheriff’s office says Fischer died of apparent asphyxiation, and that no foul play is suspected.

The incident happened at the county’s lockup in the Hibbing Courthouse, which is a temporary facility that holds up to nine people for up to 72 hours.
