  • Images and videos uploaded to Instagram and YouTube accounts connected to Aghdam, who is believed to have killed herself during Tuesday’s attack, contained political messages and fitness tips – but also featured some heavy criticism of YouTube.
  • Several of the social-media accounts – including Facebook and Instagram accounts and several YouTube channels linked to Aghdam – have been taken down.
  • Her father, Ismail Aghdam, told The Mercury News “she was angry” at YouTube.

The woman authorities say carried out Tuesday’s shooting at YouTube’s headquarters before killing herself appeared to have an active presence online. YouTube, Instagram, and Facebook accounts connected to the woman featured a wide range of content – including dancing, fitness tips, and commentary on veganism.

The police in San Bruno, California, identified the shooter as Nasim Aghdam, 39, on Tuesday night.

Aghdam had expressed some heavy criticism over YouTube’s move to demonetize certain channels. She took issue specifically with what she believed to be a targeted reduction in viewership on her videos.

Aghdam also seemed to have engaged in some political speech.

“BE AWARE! Dictatorship exists in all countries but with different tactics!” a website that appeared to be linked to Aghdam said.

An Instagram account believed to be run by her had more than 16,000 followers before it was shut down.

In one missive about YouTube’s move to demonetize certain channels, one post said: “There is no equal growth opportunity on YOUTUBE or any other video sharing site, your channel will grow if they want to!!!!!”

Aghdam, a resident of San Diego, drove from Southern California to San Bruno, the Bay Area home of YouTube’s headquarters, days before the shooting, the local news station KRON-4 reported.

She is believed to have used a handgun to shoot three people before fatally shooting herself.

A fourth person sustained injuries that were not gun-related.

The police are still searching for a motive in the attack. In the hours directly after the shooting, one law-enforcement source told Business Insider that the police initially believed the shooter knew one of the victims, but this was later contradicted by a statement from the San Bruno Police Department saying it was still investigating a motive and “at this time there is no evidence that the shooter knew the victims of this shooting or that individuals were specifically targeted.”

Multiple local news outlets, including the San Jose-based Mercury News, said Aghdam had been reported missing days before the shooting. The newspaper reported that the woman’s father, Ismail Aghdam, said she complained that YouTube “stopped everything” and told her family she was “angry.”

Update: An earlier version of this article included information from a source that said the suspected shooter had a boyfriend who worked at YouTube. The article has since been updated to take into account the most recent comment from San Bruno police, which said “At this time there is no evidence that the shooter knew the victims of this shooting or that individuals were specifically targeted.”
