After yesterday’s shooting on YouTube’s San Bruno campus that left three people injured and the shooter dead, we’re learning more about the woman who is suspected of carrying out the attack and why she might have done it.
San Bruno Police Chief Ed Barberini says the YouTube shooter was angry about the policies and practices of the company and had visited a gun range before she drove to the company's headquarters near San Francisco. He says 39-year-old Nasim Najafi Aghdam got into the building through a parking garage.
Barberini said Wednesday that investigators are in the process of executing search warrants at two properties. He also said that the gun used in the shooting was a legally purchased 9mm handgun, and that Aghdam had gone to a gun range before carrying out the shooting.
We’re also learning that at least one family member had reportedly contacted police with concerns that Aghdam “might do something,” though he apparently did not specify what that “something” might be.
We’ll get the latest from a reporter who has been covering the story, talk with a workplace security expert about how she was able to walk onto YouTube’s campus to carry out the shooting, and hear from an expert in police tactics on how law enforcement vets and triages tips from people who believe a family member may be a danger to themselves or others.
