SAN BRUNO, Calif. (AP) -- The woman suspected in the shooting at YouTube headquarters Tuesday was a 39-year-old San Diego resident.
Two law enforcement officials identified the suspect as Nasim Aghdam.
Aghdam was quoted in a 2009 story in the San Diego Union-Tribune about a protest by People for the Ethical Treatment of Animals against the use of pigs in military trauma training. She dressed in a wig and jeans with drops of painted "blood" on them, holding a plastic sword at the demonstration outside the Camp Pendleton Marine Corps base.
"For me, animal rights equal human rights," Aghdam told the Union-Tribune at the time.
Police say the shooter opened fire with a handgun at the YouTube headquarters Tuesday and wounded three people before fatally shooting herself. A fourth person injured their ankle while fleeing.
