No criminal charges will be filed in the death of a 4-year-old Kansas City girl who was accidentally shot in the head.

Jackson County Prosecutor Jean Peters Baker said Wednesday there was insufficient evidence to establish a crime was committed.

The girl’s father told police he forgot that he left the weapon in the living room. He was not at home at the time of the incident and his wife was not aware the gun was left on a chair when she left the room.

Trinity Ross was shot at a home near 105th Terrace and Monroe Avenue in south Kansas City the morning of Jan. 10. She died days later at an area hospital.
