YouTube shooting: Everything we know

A shooting at YouTube’s headquarters in San Bruno, California, left three people injured and one person dead, which has since led to numerous questions about the motive.

Police continue to give brief updates on the investigation in the shooting’s aftermath, including naming the suspected shooter as 39-year-old Nasim Najafi Aghdam, a resident of San Diego. Reports suggest that Aghdam’s unease and anger over the “policies and practices of YouTube” led to her attack on YouTube HQ, according to San Bruno’s chief of police, Ed Barberini.

Aghdam, who hosted three different YouTube channels mostly focused on lifestyle, exercise and animal rights topics, was reported missing to San Diego police on April 2, and had apparently been missing since March 31. She was discovered by Mountain View police on April 3, the same day as the shooting.

Videos featuring Aghdam began circulating Twitter after police released her name; these include Aghdam complaining about the “discrimination” her videos faced by YouTube.

Police did not confirm whether the three shooting victims were YouTube employees. (A fourth person involved in the incident was also admitted to the hospital for injuries unrelated to the gunfire.)

More information is being uncovered as the investigation continues.
