Gunfire erupted at YouTubes offices in California Tuesday, leaving three people wounded and sparking a panicked escape before the suspected shooter -- a woman who had voiced complaints online about the tech company -- committed suicide. The woman was a 39-year-old San Diego resident. Two law enforcement officials identified the suspect as Nasim Aghdam. California news outlets late Tuesday said she was a vegan-themed content creator who has raged against YouTube on her personal website for what she saw as censorship of her videos. "There is no free speech in real world and you will be suppressed for telling the truth that is not supported by the system," read a post on a website identified as hers by the San Francisco Chronicle. "There is no equal growth opportunity on YouTube or any other video sharing site." Amid a chaotic scene in the city of San Bruno, the woman believed to be the shooter was found dead at the scene of the Google-owned video sharing service. "We have one subject who is deceased inside the building with a self-inflicted wound," San Bruno Police Chief Ed Barberini told reporters. "At this time, we believe it to be the shooter." Officers arriving to numerous calls for help saw employees running from the building, and found a person out front who appeared to be shot in the leg, according to police. Four people, three suffering from gunshot wounds, were taken to local hospitals, police said. The fourth person hurt suffered a sprained or broken ankle. "I know a lot of you are in shock right now," Google chief executive Sundar Pichai said in a message to employees shared by the company on Twitter. "I am grateful to everyone inside and outside the company for the outpouring of support and best wishes." He thanked emergency workers for springing into action to help, and said that he and YouTube chief Susan Wojcicki were focused on supporting employees in the aftermath of the violence. "There are no words to describe how horrible it was to have an active shooter @YouTube today," Wojcicki wrote. "Our hearts go out to all those injured and impacted today. We will come together to heal as a family." The White House said President Donald Trump had been briefed and that his administration was monitoring the ongoing situation in San Bruno. Shortly afterward, Trump tweeted: "Our thoughts and prayers are with everybody involved. Thank you to our phenomenal Law Enforcement Officers and First Responders that are currently on the scene."
