(Radio Iowa) — A 21-year-old who was living with his 66-year-old grandmother in rural western Iowa has been charged with killing her. In late June, Cheryl Stowe’s co-workers asked the Monona County Sheriff to do a welfare check at her home near Castana. She wasn’t there, but her grandson was and authorities arrested Eliot Stowe on an outstanding warrant.

He had threatened a parole officer and court records indicate he was charged in early June with false imprisonment and assault. A day later, officers went back to the area and found Cheryl Stowe’s body about one-and-a-half miles from her home. The state medical examiner has now classified her death as a homicide.

On Tuesday, Eliot Stowe was charged with first degree murder. He’s being held at the Monona County Correctional Facility on a one-MILLION dollar cash bond.
