The Nodaway County Sheriff’s Office is investigating the death of a 9-month-old boy shot and killed Monday morning by his 5-year-old brother.

According to a press release from the Sheriff’s Office, Alexis Wiederholt called 911 at 8:58 a.m. asking for an ambulance to respond to her home located at 101 S. Scott in Elmo, Mo.

Wiederholt allegedly told dispatch her 5-year-old son had shot her 9-month-old son in the head with a paintball gun.  However, when law enforcement and medical personnel arrived it was determined that the infant had been shot in the head with a .22 magnum revolver.

The child was flown from the scene to Children’s Mercy Hospital by Life Net Air Ambulance but did not survive.

Authorities said the case appears to be accidental and no foul play is expected at this time.

The case is under investigation by the Nodaway County Sheriff’s Office.

The Missouri State Highway Patrol, Nodaway County Ambulance, Nodaway County Rescue, Clearmont Fire and Life Net Air Ambulance all assisted.
