A common theme among America’s spree killers is a fondness for rambling online. Isla Vista shooter Elliot Rodger griped about his inability to get a girlfriend. Troy Sesler made videos about anime that grew increasingly dark before he flipped out and killed his family. Randy Stair made numerous sketches and vlogs detailing his fondness for serial killers, his issues with his body image and his problems with his masculinity before massacring several of his co-workers.
