Officers found the infant suffering from a gunshot wound to the head after responding to a 911 call placed by the boys’ mother on Monday morning, according to the Nodaway County Sheriff’s Office.

The mother, identified as Alexis Wiederholt, originally told dispatchers that the tot had been shot by his brother with a paintball gun. Upon arriving at the home Elmo, Missouri, authorities determined that a .22-caliber Magnum revolver had been used, police said. Authorities believe the shooting was accidental.
