The Lake County Major Crime Task Force is investigating after an inmate at the Lake County Jail was found unresponsive and later died on Wednesday.

Lake County Sheriff Sgt. Christopher Covelli said a 31-year-old Park City man, whose name has not been released, was brought to the Lake County Jail on July 17 on felony charges.

He had been in the jail for 64 days before he was found Wednesday at 11 a.m. unresponsive in his cell in the Administrative Segregation Unit (ASU), which is the maximum security part of the Lake County Jail.

Covelli said that the man was alone at the time when he was found. First-aid and an automated external defibrillator (AED) were administered by jail security.

Paramedics were called to the scene and transported the man to Vista East Medical Center in Waukegan where he was pronounced dead.

The man was in the maximum security part of the jail, which holds one inmate in each jail cell, because he had been disruptive and threatening towards other inmates, Covelli said.

In August, a Lake County judge found the man unfit to stand trial on his charges. He was ordered to be held in the jail until the Illinois Department of Human Services could determine the appropriate action to take, Covelli added.

The Lake County Major Crime Task Force continues to conduct their independent investigation. The Lake County Coroner’s Office has scheduled an autopsy on the man.
