A woman who had voiced complaints online about YouTube opened fire with a handgun at the tech company’s headquarters near San Francisco on Tuesday, wounding three people before shooting herself dead, authorities and media said.
It was the latest in a string of mass shootings in the United States in recent years. Most recently, the massacre of 17 people at a Florida high school has led to calls for tighter curbs on gun ownership.
Police did not identify the suspect or say what might have motivated Tuesday’s shooting at YouTube, a video-sharing service owned by Alphabet Inc’s Google which employs nearly 2,000 people at the San Bruno, California offices.
The woman approached an outdoor patio and dining courtyard on the campus around lunchtime and began to fire before entering the building, police said.
An affiliate of ABC and other local media, citing unnamed sources, identified the woman as Nasim Aghdam.
San Bruno police officials could not immediately be reached for comment on the identity of the attacker.
YouTube spokeswoman Jessica Mason could not immediately be reached for comment on the identification by media.
The website NasimeSabz.com, which media said was linked to the attacker, had several posts about Persian culture and veganism, interspersed with screeds against YouTube.
Those complaints included claims the company was not sharing enough revenue with people who create videos for the platform.
“There is no equal growth opportunity on YouTube, or any other video-sharing site, your channel will grow if they want to,” read one posting on the site.
A YouTube account in the name of Nasime Sabz was deleted on Tuesday evening.
A U.S. government security official told Reuters there was no known connection to terrorism.
ABC News, citing unnamed law enforcement sources, said the suspect was 35 to 40 years old, and lived in Southern California.
A YouTube product manager, Todd Sherman, described on Twitter hearing people running, first thinking it was an earthquake before he was told that a person had a gun.
“At that point every new person I saw was a potential shooter. Someone else said that the person shot out the back doors and then shot themselves,” Sherman said in a tweet.
“I looked down and saw blood drips on the floor and stairs. Peeked around for threats and then we headed downstairs, and out the front,” Sherman said.
In a recording of a 911 call posted online by the Los Angeles Times, a dispatcher can be heard saying: “Shooter. Another party said they spotted someone with a gun. Suspect came from the back patio … Again we have a report of a subject with a gun. They heard seven or eight shots being fired.”
