The female suspect in the YouTube shooting on Tuesday appeared to have an active presence online. YouTube, Instagram, and Facebook accounts connected to the woman featured a wide range of content - from dancing to fitness tips and commentary on veganism.
Law-enforcement officials identified the suspected shooter as Nasim Aghdam on Tuesday night.
The woman had expressed some heavy criticism for YouTube's move to demonetize certain channels. She took issue specifically with what she believed to be a reduction in viewership on her videos.
Aghdam, who is believed to have been in her late 30s, also engaged in some political speech.
"BE AWARE! Dictatorship exists in all countries but with different tactics!," a website that appeared to be linked to her Instagram page said.
Her alleged Instagram account had over 16,000 followers before it was shut down.
In one missive about YouTube demonetization, Aghdam said: "There is no equal growth opportunity on YOUTUBE or any other video sharing site, your channel will grow if they want to!!!!!"
Aghdam reportedly drove from Southern California to San Bruno, 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.
Multiple local news outlets, including the San Jose-based Mercury News said that 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."
