A woman opened fire at YouTube headquarters in San Bruno, Calif., shooting three people with a handgun before taking
her own life and causing widespread panic in the technology hub south of San Francisco.
San Bruno police identified the shooter as Nasim Aghdam, 39, a San Diego resident.
Investigators initially believed the shooting was a domestic incident, with the shooter targeting someone who worked on the YouTube campus. But San Bruno police said in a release late Tuesday that "there is no evidence that the shooter knew the victims of this shooting or that individuals were specifically targeted."
One law enforcement source said the investigation is now looking into a website that appears to show the same woman complaining about YouTube stifling traffic and suppressing videos. The source stressed that the investigation is in its preliminary stages.
