Frederick mother charged after 3-year-old son shot and killed himself

WELD COUNTY, Colo. - The mother of a child who shot and killed himself in Frederick is being charged.

Dione Warren called 911 on Oct. 28 and told dispatchers her son was lying on the floor, wasn't breathing and was bleeding from the head. The coroner's office determined that 3-year-old Sheine Steine died from an accidental, self-inflicted gunshot wound.

Investigators said they determined that Steine found the gun between the mattress and frame of a bed after Warren left him home alone while she took her older daughter to school.

Prosecutors decided to file charges of criminally negligent child abuse resulting in death against Warren.

The semiautomatic gun was legally owned by the boy's stepfather who was not home at the time.
