On Tuesday, April 3, YouTube’s headquarters in San Bruno, California was attacked by Nasim Aghdam, a female shooter, which resulted in four injured and one dead. The only person declared dead in the incident was the shooter herself, who committed suicide at the headquarters. Of the four injured, three had gun-related injuries, while one sustained an ankle injury when fleeing from the scene.

Law enforcement has been looking into a website blog they believe might belong to the shooter because it reiterates many of the grievances she had towards YouTube following the demonetization of her account. The site states, “Youtube filtered my channels to keep them from getting views! There is no equal growth opportunity on YOUTUBE or any other video sharing site, your channel will grow if they want to!!!!!”

According to YouTube, the company terminated her account “due to multiple or severe violations of YouTube’s policy against spam, deceptive practices, and misleading content or other Term of Service violations.”

The day before the shooting, Aghdam’s father, Ismail Aghdam, reported his daughter missing to authorities because she had not been answering her phone in days. He also told law enforcement that he believed she would be going to the YouTube headquarters because she expressed dislike towards the company; however, her father did not mention anything about a possible shooting or about his daughter being armed.
