PORTAGE, Wis. (AP) -- Authorities are investigating a Columbia County prison inmate's death.
WKOW-TV reports that the Columbia County Sheriff's Department was notified of a medical emergency in the prison Thursday afternoon. A 40-year-old male inmate was pronounced dead at the scene.
The sheriff's office says it is investigating whether another inmate was involved in the death.
Officials say an autopsy is scheduled and they will not release the inmate's name until family members have been notified. Officials with the sheriff's department and the state Department of Corrections didn't immediately return messages from the Associated Press on Friday.
