YouTube shooter visited gun range before attack: Police

San Francisco: The woman who opened fire at YouTube headquarters in California over the video sharing platform’s “discriminatory” treatment to her postings, practiced shooting at a gun range hours before the attack, police said. The 39-year-old Nasim Najafi Aghdam, a Californian resident of Iranian descent, opened fire in a courtyard at YouTube’s offices in San Bruno on Tuesday. After practicing, Aghdam then took her 9 mm Smith & Wesson handgun to the Silicon Valley campus and shot three people she apparently did not know, CNN quoted San Bruno Police Chief Ed Barberini as saying on Wednesday. “We know she was upset with YouTube, and now we’ve determined that was the motive,” Barberini said. Aghdam shot and wounded three people before killing herself. Two of her victims have been released from the hospital, and one remains in serious condition.
