Californian media reported that Aghdam’s family had warned authorities that she could target YouTube prior to the shooting. The San Jose Mercury News quoted her father, Ismail Aghdam, as saying he had told police that she might go to YouTube’s headquarters because she “hated” the company.
Efforts to reach her relatives by phone were unsuccessful.
Her family in Southern California recently reported her missing because she had not been answering her phone for two days, police said.
At one point Tuesday, Mountain View, California, police found her sleeping in her car and called her family to say everything was under control, hours before she walked onto the company grounds and opened fire.
A survivor of the February shooting at Marjory Stoneman Douglas High School in the Parkland, Florida, weighed in on the YouTube incident on Wednesday.
“The YouTube HQ shooting is proof that this is NOT just schools,” Jaclyn Corin said on Twitter Wednesday. “Our country has a GUN problem. End of story.”
Gun rights advocates have argued that more armed guards and citizens could prevent mass shootings.
YouTube has long faced complaints about alleged censorship on its site, and says it attempts to balance its mission of fostering free speech while still providing an appropriate and lawful environment for users.
In some cases involving videos with sensitive content, YouTube has allowed the videos to stay online but cut off the ability for their publishers to share in advertising revenue.
Criticisms from video makers that YouTube is too restrictive about which users can participate in revenue sharing swelled last year as the company imposed new restrictions.
