Authorities in California have released body camera footage showing officers approach a woman sleeping in her car early on the morning of April 3.

Later the same day, police say the same woman would be dead after perpetrating a mass shooting at the headquarters of YouTube.

According to Fox News, Mountain View police spotted 39-year-old Nasim Aghdam parked at an empty Walmart.

Upon questioning by authorities, the woman said she left San Diego amid a family rift. Relatives reported her missing the previous day.

Officers reportedly contacted the woman’s father after the interaction, leading him to suggest she was in the area because she had “recently become upset about changes on the YouTube platform that had impacted videos she had created on living a vegan lifestyle.”

The extent of her animosity toward the video streaming platform, which appear to be rooted in decreased payment for views, is still unclear.

Police say that about 11 hours after police spotted her sleeping in her car outside of a Mountain View Walmart, however, she appeared outside of YouTube’s San Bruno headquarters with a firearm.

She allegedly shot three individuals before turning the gun on herself and firing a fatal shot.

As CrimeOnline previously reported, members of Aghdam’s family issued a statement shortly after the shooting expressing condolences and indicating that they had contacted police to warn of a possible attack on YouTube.

Authorities initially dismissed that allegation.

“At no point during that conversation did either Aghdam’s father or brother make any statements regarding the woman’s potential threat to, or a possible attack on, the YouTube campus,” said San Bruno Police Chief Ed Barberini at the time.
