AZUSA - A domestic dispute ended early Thursday when an estranged husband, and father of two, shot himself in the head.

Azusa police responded to a home in the Caravan Trailer Park in the 600 block of West Gladstone Street early Thursday after a woman drove to the police station to report her 46-year-old estranged husband had shown up to her home with a gun.

"There was a verbal argument," Azusa police Sgt. John Madaloni said. "He raised his shirt to expose a handgun."

SWAT team members and police surrounded the home and tried to contact the man by phone and loud speaker. Those calls went unanswered, according to police.

"It was at that time they heard a single gunshot," Madaloni said.

Police discovered the man's body on the porch with a single gunshot wound to the head, according to Detective Sgt. Bruce Badoni.

The husband and wife had been separated for four months, according to neighbors.

"He would always come over and drink beer and visit with his kids on the porch," neighbor Gilbert Ruiz said. "But he would never go inside."

The couple had two girls approximately 5 and 14 years old. They had accompanied their mother to the police station, according to authorities.

"Saturday, he was building a little play desk for his daughter and drinking by his truck," Ruiz said.

Earlier on Wednesday evening, the man had been seen milling around the park and drinking alcohol, according to authorities.

The man's name has not yet been released.
