A woman who is suspected of injuring three people in a shooting at YouTube's headquarters near San Francisco has been identified.
Police named San Diego resident Nasim Aghdam (39) as the suspected attacker.
Her body was discovered at the video-sharing site's base in San Bruno after apparently turning a handgun on herself.

Aghdam had videos on the site - but had complained she wasn't getting enough views.
In what appears to have been her own website, she accused employees of "filtering my videos to reduce views & suppress & discourage me from making videos!"
She is believed to have had multiple YouTube channels, but they have now been removed from the site.
One of the three people injured in the attack is in a critical condition - with one other seriously injured, and another in a stable condition.
Police said: "The San Bruno Police Department is investigating a motive for this shooting.
"At this time there is no evidence that the shooter knew the victims of this shooting or that individuals were specifically targeted. "
A number of YouTube employees shared their experience of the attack, including CEO Susan Wojcicki:
There are no words to describe how horrible it was to have an active shooter @YouTube today. Our deepest gratitude to law enforcement & first responders for their rapid response. Our hearts go out to all those injured & impacted today. We will come together to heal as a family.

Police cruisers pull up, hopped out with rifles ready and I told them where the situation was as I headed down the street to meet up with a couple team members.
