Distressing bodycam video has shown the moment ER star Vanessa Marquez was shot dead by cops after pulling out a replica gun and shouting 'kill me' during a welfare check at her home.
Marquez, 49, can be seen sitting in her bedroom after police officers were called to the property in South Pasadena, California, by a concerned friend on August 30, 2018.
'I'm not going,' the actress tells the pair of officers after they tell her she has been placed on a Section 5150 hold for her own safety. She is then seeing drawing a pair of scissors from a handbag, followed by pistol, which was later found to be BB gun.
One of the officers says: 'Wait, wait, wait, wait, wait, s**t, she's got a gun. She's got a gun. Gun! Gun! Gun!' And the police immediately back out of the apartment.
In harrowing footage, the officers can be heard pleading with Marquez to drop the gun while they wait at the bottom of the stairs. The actress appears on the steps holding the gun before the officers open fire.

Shannon Presby, head deputy district attorney, wrote in a memo: 'In this incident, the evidence demonstrates that Carrillo and Perez actually and reasonably believed Marquez posed an imminent threat of great bodily injury or death.'
Police later determined that the weapon Marquez had allegedly picked up was a realistic-looking BB gun. Indeed, when Marquez emerged from the apartment, Carrillo told investigators he heard the sound of a clip being inserted and a slide being racked.
