2. She described herself on YouTube as a "vegan bodybuilder" and "animal rights activist promoting healthy and humane living." NBC News reported that many of her videos "focused on animal rights and veganism, mixed in with bizarre musical parodies." On her website, Aghdam claimed that she created "the very first Persian vegan TV commercial and vegan music video" in 2010.

3. She believed that YouTube was trying to reduce her video views and suppress her content. "She was always complaining that YouTube ruined her life," her brother, Shahran, told the Mercury News.

"She was angry," added her father, Ismail.

Aghdam slammed YouTube on her website, saying one of her workout videos "got age restricted after new close-minded youtube [sic] employees, got control of my farsi youtube channel last year 2016 & began filtering my videos to reduce views & suppress & diacaurage [sic] me from making videos!"

She added: "There is no free speech in real world & you will be suppressed for telling the truth that is not supported by the system. Videos of targeted users are filtered & merely relegated, so that people can hardly see their videos!"

4. Her father said he reported Aghdam missing before the shooting and warned police that she was angry with YouTube. According to the Mercury News, police in Mountain View found her sleeping in her car and called him early Tuesday. He said officers told him that the situation was "under control."

5. San Bruno police said there's "no evidence" that Aghdam knew the victims "or that individuals were specifically targeted." According to The Associated Press, the injured include a man, 36, in critical condition; a woman, 32, in serious condition; and another woman, 27, in fair condition.

Investigators are still trying to determine a motive.
