O'FALLON, Mo. • A man suspected of forcing his way into his daughter's St. Peters home fatally shot himself here Thursday night as he was approached by police outside a convenience store.

The man, 54, was sitting in his car with the windows closed when he shot himself in the head in the parking lot of a QuikTrip at 801 Belleau Creek Road, according to O'Fallon police. He was transported to a hospital, where he died of his injuries.

St. Peters police said the man's daughter had said in a 911 call that the man forced his way into her home in the 4000 block of Chadwick Lane at about 7 p.m.

She said he appeared highly intoxicated, displayed a gun and threatened to kill himself; she was hiding in a room in the home as she made the call. He left the home before police arrived.

Police then began looking for him to arrest him for home-invasion burglary but were also concerned about his well-being because of his suicidal statements.

Officers with O'Fallon, St. Peters and St. Charles County were called to the QuikTrip after his car was spotted there at about 8:30.
