The YouTube shooter used a handgun in the San Bruno attack, police said
- Authorities said the woman who injured three people and killed herself at YouTube's California headquarters on Tuesday used a handgun in the rampage.
- Police identified the woman as Nasim Aghdam, a San Diego woman in her late 30s.
- Aghdam's father and brother have said she bore a grudge against the video-streaming platform after they demonetized her videos, though police say her motive was unclear.
The woman who opened fire in YouTube's California headquarters on Tuesday, injuring three people before killing herself, used a handgun in the attack, police said.
San Bruno's police chief, Ed Barberini, told media there was no evidence so far to suggest that her gun was obtained illegally.
Authorities identified the woman as Nasim Aghdam, a San Diego woman in her late 30s, whose father told local media that she bore a long-standing grudge against the video-streaming platform after they demonetized her videos.
Police in Mountain View also said they came into contact with Aghdam on Tuesday morning hours before the shooting, after finding her asleep in a parked car. Her family had reported her missing.
Aghdam's brother told CNN affiliate KGTV that after he learned Aghdam was in Mountain View, he feared she would do something dangerous. He declined to be identified by the station.
"I Googled 'Mountain View,' and it was close to YouTube headquarters. And she had a problem with YouTube," he told KGTV, adding that he called police to say "she went all the way from San Diego, so she might do something."
San Bruno police said Aghdam's motive was still unclear, and there was no evidence to suggest that the three victims she wounded were "specifically targeted," The Los Angeles Times reported.
The shooting quickly exacerbated nationwide tensions over gun violence and proposed gun-control measures, an issue which had already come to a head following a mass shooting at a Florida high school in February.
