William Devin Howell can best be described as a drifter. In 2003, he roamed the streets of Connecticut in his van that he dubbed his "murder mobile." The name makes sense because, at that time, Howell abducted, assaulted, and murdered seven people, according to Oxygen. He buried the bodies in his "garden" behind a strip mall as a memorial.
On trial, Howell said he could not explain his motive behind the killings, referencing a "monster" inside him. "I know everyone wants to know why I committed these crimes. I don't have an answer. I do not know myself," he said at the time.
In 2017, he was sentenced to 360 years in prison.
