The body cam footage of a police encounter with YouTube shooter Nasim Aghdam has been released.
Police have released body cam footage of their encounter with Nasim Aghdam, hours before she entered the YouTube headquarters and opened fire.
The video was made public Friday. It shows officers speaking with Aghdam in her car, telling them she has no intention of hurting herself or others.
Aghdam had been reported missing by her family in Southern California before police found her asleep inside her car in the city of Mountain View, about 48 kilometres south of the YouTube headquarters.
In the footage filmed in a WalMart car park about 1.30am on April 3 (US time), she was woken up by officers and appeared to be cooperative and calm.
About 11 hours later she opened fire in a courtyard at the company's headquarters, wounding three people before taking her own life.
Investigators say she was angry about the company's policies.
During the police interview with Aghdam, an officer checked her licence plate and was informed that the car's owner was a missing person.
Aghdam tells them that she left her home in San Diego because she was not getting along with her family.
The officers asked her if she was taking any medication or if she was thinking of harming herself or was going to hurt anyone else. Aghdam shook her head and responded "no" to all three questions.
She had purchased a 9mm handgun that she used in the shooting months earlier. Police claim she had visited a gun range on the morning of the shooting.
The Mountain View officers did not ask Aghdam if she had any weapons in her car. If she did not have the gun secured in the trunk or a locked container, Aghdam could have been arrested.
Police say they checked several databases, including a statewide database that would indicate if someone is a registered gun owner but prohibited to possess firearms.
Officers contacted Ismail Aghdam, her father, who informed them they weren't getting along. He thanked the officers for finding her safe.
About an hour after initially speaking with him, Ismail Aghdam contacted police again to tell them he believed his daughter may have been in the area because she "recently become upset about changes on the YouTube platform that had impacted videos she had created on living a vegan lifestyle," police said in a statement cited by Associated Press.
Police said Aghdam's father did not indicate that she was a danger to herself or anyone else.
Nasim Aghdam uploaded videos to YouTube under the name Nasime Sabz.
