A 19-year-old Yelm man was found dead in his cell early Tuesday at the Nisqually Jail.
The man’s name is being withheld until next of kin are notified. An autopsy is scheduled for Thursday to determine the cause of death, said Thurston County Coroner Gary Warnock.
Warnock confirmed there were no signs of suicide or assault, and that the man was found unresponsive in his cell. It is unknown if the man had any pre-existing medical conditions.
The Yelm Police Department confirmed that the man was arrested at 10:41 p.m. Sunday in the 16500 block of SR 507 on suspicion of fourth-degree assault and being a minor in possession.
