In a brief press conference Wednesday morning, San Bruno Police Chief Ed Barberini told reporters that the YouTube shooter had legally purchased her handgun and that she had trained on a local range prior to the incident.

Late Tuesday evening, the San Bruno Police Department, which serves YouTube’s hometown, identified the suspect in Tuesday’s shooting at the YouTube campus as Nasim Aghdam, a 39-year-old woman from San Diego. She ended the shooting when she took her own life.

While Barberini declined to name the gun range, there is one just three miles away from YouTube’s headquarters in the nearby city of South San Francisco.
