Marquez was known for her roles in "ER" and "Stand and Deliver".
According to The Hollywood Reporter, officers visited Marquez's home in South Pasadena, Calif. on Thursday, Aug. 30, 2018, to perform a welfare check on the woman after receiving an "emergency medical call". Officers later recovered the weapon, which was discovered to have been a BB gun that was made to resemble a semi-automatic handgun.
South Pasadena police shot and killed Marquez during a welfare check Thursday afternoon, according to police reports.
Following the altercation, "the suspect was transported to a local hospital where she was pronounced dead". In 2017, she accused George Clooney of hurting her career during their "ER" days, saying he helped "blacklist" her when she reportedly spoke up about alleged harassment on the show. She appeared on the "Cheever Letters" episode of "Seinfeld", and had roles in movies "Stand and Deliver" and "Blood In, Blood Out".More news: Suspects detained over death of rebel leader in Ukraine

Vanessa Marquez (49) played nurse Wendy Goldman on the hit United States series from 1994 to 1997.
Clooney said in a statement to US Weekly at the time that he was just an actor on the show and was unaware of any blacklist. "The fact that I couldn't affect her career is only surpassed by the fact that I wouldn't".
Lt. Joe Mendoza added that Marquez had been suffering from eating disorders and appeared to be gravely disabled. He was neither an actor, a producer, a director, or a casting director, he was "only an actor". Additionally, the actor explained, not only was it impossible for him to ruin her career, he wouldn't either even if he had the chance.
Her death is under investigation, which is standard practice for police-involved shootings.
On August 8, Marquez posted what would be her final Facebook status update, accusing Jack Dorsey, the CEO of Twitter, of hypocrisy. She had also claimed she had been groped on the set of ER, but when she spoke out, she was blacklisted.
