ST. LOUIS COUNTY, Mo. – Police said a 4-year-old boy accidentally shot himself and died Thursday after finding a loaded gun and playing with it in north St. Louis County.

A spokesperson for the North County Police Cooperative told FOX 2 the incident happened around 1 p.m. in the 10000 block of Olney Drive in Dellwood. When officers arrived, they found the boy inside a home suffering from a gunshot wound.

First responders performed life-saving measures on the child but were unsuccessful. Police said the boy died at the scene. A parent was also home at the time of the incident.

“That parent is being very corporative with us,” said North County Police Cooperative Major Ron Martin.

A neighbor, Ashley Taylor, offered her condolences to the family.

“My son just played with him outside yesterday,” she said. “It’s a tragedy that happened. My heart goes out to the family. I could not imagine losing one of my children.”

Police are still investigating the circumstances leading up to the child’s death. At this point, it’s unclear who the gun belongs to or how the child got ahold of the weapon.
