Hollywood actor Vanessa Marquez was shot and killed by police in Pasadena city.

According to a TMZ report, police arrived after Marquez's concerned landlord called them up to check on her, as she was said to be suffering from seizures due to an eating disorder.

Variety reported that after the paramedics were called in to take care of her health, the 'Fire and Ice' actor took out a gun and pointed at the police. It is after such an act that the police opened fire at her.

Vanessa, who was rushed to the hospital, was declared brought dead. It later turned out that the weapon she was holding was a mere BB gun.

Officers had gone to her home in the Los Angeles suburb of Pasadena on Thursday to conduct a welfare check when the 49-year-old Vanessa Marquez grabbed what looked like a handgun and pointed it at officers, said Sergeant Joe Mendoza, of the LA Sheriff's Department.

He said after the incident "officers checked the weapon and they discovered it was a BB-type gun that resembled a semi-automatic handgun."

Mendoza said Vanessa Marquez's landlord had called police to check on her and when officers arrived she appeared to be having a seizure.

He said the officers and a mental health clinician spoke with Vanessa Marquez "for over an hour and a half in an attempt to offer her medical care."

"She then armed herself with a handgun and pointed it at the officers, at which time an officer-involved shooting occurred," he said.

Vanes was only 49 years old.
