Police have named Nasim Aghdam, 39, as the woman who shot and wounded three people at YouTube’s headquarters in Northern California before killing herself.
They say there is no evidence yet that she knew the victims, a 36-year-old man said to be in a critical condition, and two women aged 32 and 27.
Aghdam had in the past posted material venting anger at YouTube.
Such “active shooter” incidents are overwhelmingly carried out by men – an FBI report found that out of 160 incidents between 2000-2013 only six of the people who opened fire were women.
What happened?
The suspect is reported to have approached an outdoor patio and dining area at the offices in San Bruno, near San Francisco, at about lunchtime and opened fire with a handgun.

San Bruno Police Chief Ed Barberini said officers arrived at the offices at 12:48 (19:48 GMT) local time to find a “chaotic scene”, with numerous people fleeing.
Images broadcast on local TV stations showed employees leaving with their hands raised. Other footage showed evacuees forming a queue before being individually frisked by police.
One person with a bullet wound was found at the front of the company headquarters, Mr Barberini said. Minutes later officers found a woman who appeared to have shot herself, he said.
When I watch this video of the YouTube HQ San Bruno shooter Nasim Aghdam, it seems explicitly clear that a mental health crisis is the problem we’re facing. Another mentally ill killer who ended up an extremist. Very sad. pic.twitter.com/xWwnyUEdrW

IF the shooter, Nasim Aghdam is the same Nasim I knew years ago who attended many animal protests in San Diego, she was definitely NOT a jihadi. The Nasim I knew was very sweet, very shy, a loner, very artistic. She was always taking photos. My pic from 2011 pic.twitter.com/BLJ0rjXi1h

Two further victims were later discovered at an adjacent business.
An employee at a nearby fast food restaurant told Fox station KTVU he had treated a young woman who suffered a bullet wound to the leg.
He said he had fashioned a makeshift tourniquet from a bungee cord as they waited for first responders.
Several YouTube employees tweeted about the attack as it was taking place.
Product manager Todd Sherman said people fled the building in panic as the shooting unfolded.
Another employee, Vadim Lavrusik, tweeted he was barricaded in a room with other staff. He later said he had been evacuated.
The three wounded were taken to Zuckerberg San Francisco General Hospital. Officials said the 32-year-old woman’s condition was serious and the 27-year-old’s condition was fair.
A fourth person was also taken to hospital with an ankle injury sustained while trying to escape, Mr Barberini said.
Some 1,700 people work at the YouTube HQ. The company is owned by Google and is the area’s biggest employer.
Who was the suspect?
San Bruno police identified the suspect as Nasim Aghdam, a Californian resident of Iranian descent.
She appeared often on YouTube and in one of her videos criticised the platform for discriminating against and filtering her posts.
YouTube terminated her account following the shooting. Her Instagram and Facebook accounts have also been removed.
On her personal website she accused YouTube of taking steps to prevent her videos from getting views.
“There is no equal growth opportunity on YouTube or any other video sharing site. Your channel will grow if they want to!” she wrote.
There had been earlier media reports that the man shot was her boyfriend, but police later said; “At this time there is no evidence that the shooter knew the victims of this shooting or that individuals were specifically targeted.”
