Holden's Manifesto

This episode is based on the 2014 Isla Vista killings. Holden March is based on the perpetrator Elliot Rodger, who sent an email titled "My Twisted World" to acquaintances and family before going on the shooting. The document quickly became known as his "manifesto". Rodger's had issues feeling he had been rejected by women, despite hardly interacting with them. He also uploaded a video to YouTube (later taken down) before the incident called "Elliot Rodger's Retribution", where he talked of the upcoming attack, and his motives behind it: his desire for revenge against women and sexually active men he perceived to be living a better life than his.

When searching the suspect's apartment, the squad uses gloves for everything they touch, but Nick turns on the light with his bare hand.
