However, when the 22-year-old’s parents, Lichin and Peter Rodger, arrived on the scene at Isla Vista, they were notified that their son had already killed six people, and himself.

Just a few hours before the incident, Elliot had emailed his 141-page manifesto to several people, including his parents and one of his therapists, according to Hollywood Life.

Simone Astaire, a family friend, also received the email and told Elliot’s parents to check theirs too. After they did, Lichin checked Elliot’s YouTube channel, where he had posted new videos where he talked about his “retribution,” prompting her and Peter to travel to Isla Vista, according to LAist.

Elliot Rodger had three semi-automatic weapons in his bedroom and had planned the incident beforehand, according to the Los Angeles Times.
