The woman who opened fire at YouTube’s headquarters Tuesday visited a Bay Area gun range hours before shooting, San Bruno police announced Wednesday.
San Bruno Police Chief Ed Barberini says Nasim Aghdam was upset with policies and practices of Youtube.
Aghdam wounded three people at YouTube’s headquarters before fatally shooting herself.
Barberini says 39-year-old Aghdam got into the building through a parking garage.
She used a 9 mm Smith & Wessen handgun registered to her.
Investigators are in the process of executing search warrants at two properties.
Aghdam’s family reported her missing on April 2. She had been missing since March 31.
Police located Aghdam the night before the shooting sleeping in her car in Mountain View.
Police who talked to the woman say the family gave no warning she might commit violence.
The brother of the shooting told KGTV they warned police of her hatred of YouTube and said “something might happen.”
