YouTuber Turned Family Annihilator_ The Insane Case of Trey Sesler

Trey Sesler, known online as "Mr. Anime," was a popular YouTube reviewer who became a family annihilator. He had been studying serial killers and planning a Columbine-style attack for years. On March 19, 2012, he lured his mother to the garage and shot her, then killed his brother and father. He destroyed the house and killed the pets before driving to his old high school with 100 rounds of ammunition. He backed out at the last moment, saying it became "too real." He was arrested and is serving a life sentence.
