On April 3 at the YouTube headquarters in San Bruno, California, police responded to multiple 911 calls regarding a possible active shooter in the area.
KRON4, a San Franciso-based news network, reports that one witness heard 20 different shots at one point, and at 1:00 PM local time that day, the San Bruno Poice Department tweeted that residents should stay away from 901 Cherry Ave. due to "police activity."
Product Manager Todd Sherman had an ongoing thread about his personal encounter, with another employee (Vadim Lavrusik) saying that they heard shots and was then barricaded inside a room with their coworkers.
Hours after this story broke, it was discovered that the shooter was Nasim Najafi Aghdam – a female who apparently had something of a grudge against YouTube due to the company censoring the videos she uploaded to the site.
Aghdam injured three people during the shooting before she was also deceased due to a self-inflicted wound.
