A Taylorsville SWAT team operation ended when police discovered a man dead from a self-inflicted gunshot wound Friday night, police said.

The 52-year-old man had locked himself in a bedroom while fighting with his girlfriend in a house near 3700 West and 5100 South, said Taylorsville Police Detective Shannon Bennett.

After he locked himself inside, the girlfriend and her granddaughter, who was also in the house, heard a shot and saw a round come through a wall toward them 9 p.m., Bennett said.

"They weren't sure if he was shooting at them," Bennett said, so they left the house and called police.

SWAT team officers arrived and set up a perimeter around the house. They tried to make contact with the man, but when they got no response, they entered the room. About midnight, officers found him dead of a single gunshot wound.
