Foul play is not suspected in the death of a 25 year old Marysville man found dead in his cell at the Marshall County Jail Saturday afternoon. Justin Welch was found unresponsive, in his cell alone, with no cell mate. He was being held on misdemeanor charges filed last Wednesday. Kansas Bureau of Investigation will perform an investigation, and an autopsy will be performed to determine cause of death, as is required when an inmate is in custody at the time of death. Officials did not explain how Welch died.
