PACIFIC PALISADES—A man was found dead in a Pacific Palisades mansion on Thursday, August 10 following an hours-long standoff, during which an officer-involved shooting transpired, the Los Angeles Police Department (LAPD) reported.

A SWAT team responded to a domestic dispute report at the 1600 block of Alta Mura Road at about 10:50 p.m. on Wednesday, August 9, LAPD Officer Liliana Preciado indicated. The incident began as an altercation between the homeowner and a man with whom she had an “on-again, off-again” relationship, officials said.

The woman managed to escape unharmed when the suspect arrived at the two-story, 9,000-square-foot residence and fired several shots, according to LAPD Police Captain Brian Wendling. The suspect, who was in his 50s, barricaded himself inside the home. He was believed to have been drinking heavily, officials said.

Officers were initially in contact with the suspect, but he reportedly stopped communicating with them shortly before 6 a.m. Multiple rounds of tear gas were fired into the sprawling residence during the standoff. Officials indicated it was difficult to locate the suspect because of the large size of the property. Shortly after 5 a.m., the suspect fired a shot at the police, prompting an officer-involved shooting. No officers were injured in the shootout.

Just before 11 a.m., the LAPD reported the man was found dead on the second floor of the home. It was unclear whether he died of a self-inflicted gunshot wound or from shots fired by officers. The name of the suspect has not been released to the public.
