A Las Vegas man who stabbed his mother to death in an Irvine neighborhood last month was fatally shot by police after lunging toward an officer while armed with a knife, a critical-incident report released by authorities on Tuesday, Sept. 24, shows.

Around 2:50 p.m. on Aug. 8, a 911 caller said that a man was attacking the man’s mother outside a residence along the 4600 block of Green Tree Lane, near Coral Tree Lane, Irvine police Sgt. Leticia Hernandez said in the video report. The caller said the man was armed with a large kitchen knife and had been arguing with his mother for about a half-hour, demanding they go back inside the home.

A few neighbors tried to intervene before police arrived, but were unable to get close to the two.

The man, identified as 37-year-old Paul Parveaz Montazer, was stabbing his mother in the driveway of their home when police arrived, body-worn camera footage shows.

Montazer, still leaning over his mother and armed with the knife, lunged toward an officer who had ordered him to drop the weapon, video shows.

Montazer was shot at least six times by police and pronounced dead at the scene.

His mother, Parvin Montazer, 72, also died at the scene.

A motive for the killing was still not determined, Irvine police said, adding they were continuing to investigate the case. The Orange County District Attorney’s Office was investigating the actions of the officers.

Court records show Parvea Montazer had a criminal history in Las Vegas, including a 2019 charge for misdemeanor domestic battery, and a battery charge in 2022 for resisting a police officer.
