An inmate at the Fort Dodge Correctional Facility has been charged for the murder of Warren County criminal Thomas Daleske.

According to the Iowa Department of Corrections, Daleske was found dead in his cell earlier this month, and the Webster County Medical Examiner and Iowa DCI determined the cause of death to be strangulation and blunt force injuries to the head. After investigation, it was determined that inmate 44-year-old Eric Hall had been inside Daleske’s cell shortly before the body was discovered, and while being interviewed Hall admitted to the murder. Hall has been charged with 1st Degree Murder in Webster County and remains in custody at the Fort Dodge Correctional Facility.

Daleske, who had lived in rural Ackworth, was serving a 45-year sentence for multiple counts of sexual abuse and lascivious acts with a child and was accused of raping at least eight boys in Warren County dating back to 1986, working as a volunteer with a local Boy Scout troop.
