Crime Scene Revealed: Shocking Photos Of Where ‘ER’ Star Was Shot Dead By Cops

According to cops, “officers from South Pasadena Police Department were in an apartment complex at the location conducting a welfare check for a female resident who was possibly suffering from a medical condition.”

When officers arrived at approximately 12:00 p.m., "they noticed the female was having seizures,” authorities stated.

“They requested fire department paramedics to respond and assist with her medical needs,” cops continued.

However, according to LASD, “While speaking to her, officers became aware she was possibly suffering from mental health issues, became uncooperative, and appeared to be unable to care for herself.”

A Los Angeles County Mental Health clinician was on scene with officers from the South Pasadena police department.

“They continued to speak to her for over an hour and a half in an attempt to offer her medical care,” LASD’s blast stated.

Unsuspectingly, Marquez “armed herself with a handgun and pointed it at the officers, at which time an officer-involved shooting occurred,” cops claimed.

Marquez was transported to a local hospital, where she was pronounced dead. No officers were injured. “The weapon recovered at the scene was a BB gun, and described as a replica semi-automatic handgun,” LASD’s latest release revealed.
