A YouTube sign is shown across the street from the company's offices in San Bruno, Calif., Tuesday, April 3, 2018.
The brother of Nasim Najafi Aghdam anxious she might do something unsafe when he found out she had driven over 500 miles and was close to YouTube's headquarters.
On her website she also ranted against YouTube, saying: "Videos of targeted users are filtered and merely relegated, so that people can hardly see their videos".
Aghdam wounded three people after opening fire on YouTube staffers Tuesday afternoon.
She had legally bought the 9mm handgun from a dealer in San Diego in January, and it was registered in her name, Caldwell said.
YouTube said it would ban videos that promote or link to websites selling firearms and accessories, including bump stocks, which allow a semi-automatic rifle to fire faster. It lists four YouTube channels for the woman - one in Farsi, one in Turkish, one in English and one devoted to hand art. She also focused on what she perceived as "discrimination" by YouTube and Google.
She blamed YouTube for "demonetizing" her videos and cutting her ad revenue, according to ABC 10. "Your channel will grow if they want to [sic]".
Aghdam's brother said he warned police in advance that his sister "might do something".
While Aghdam's family recalled telling Mountain View officers that she might be in the Bay Area because of her grudge against YouTube, police asserted that at no time during their 20-minute conversation with Aghdam, or in two subsequent phone conversations with her father and brother, was there was any mention of her planning an attack at YouTube, or any potential violence from her.
The discovery anxious her brother. She was nearly 500 miles away from home and only about 30 miles away from YouTube at the time. A woman opened fire Tuesday at YouTube headquarters, wounding some people before fatally shooting herself as terrified employees huddled inside, police and witnesses said. On Wednesday, investigators were conducting searches at two properties, San Bruno Police Chief Ed Barberini said.
At one point Tuesday, Mountain View, California, police found her sleeping in her auto and called her family to say everything was under control, hours before she walked onto the company grounds and opened fire. They spoke with her and found that Aghdam did not exhibit any signs that would indicate she could be a harm to herself or others so they let her go on her way. "Throughout our entire interaction with her, she was calm and cooperative". Heard shots and saw people running while at my desk. "First thought was quake". He dashed toward the exit, where someone said there was a person with a gun. He continued, "I looked down and saw blood drips on the floor and stairs".
The shooter got into the building through a parking garage.
YouTube was founded in February 2005 and quickly became a major site for online videos. Google purchased YouTube in 2006 for $1.65 billion in stock. Youtube employs close to 2,000 people at the building where it happened.
