BLOOMINGTON, Ill. (WMBD) –A man representing himself in connection with the disappearance and death of a McLean County woman killed himself while in jail, officials said. 

Correctional officers at the McLean County Jail found Joshua Livingston, 41, of Danvers unresponsive at approximately 9:33 p.m. while conducting a security check in the facility.

Officers and the members of the Bloomington Fire Department responded immediately to begin life-saving measures but Livingston was pronounced dead at 10:22 p.m. by the McLean County Coroner’s Office.

An autopsy is scheduled to be performed by the coroner’s office later this week to determine the cause and manner of death.

Livingston had been in jail since April 26 on charges of first-degree murder, concealment of a homicidal death, and possession of a stolen motor vehicle.

Prosecutors had alleged he strangled 39-year-old Melissa Sue Ostrom who was reported missing on April 17. Her body was found a few days later.
