William Devin Howell (charged)
In 2015, the remains of four people were found behind a Connecticut strip mall. It was the same desolate stretch of land where investigators had discovered three other bodies back in 2007. Investigators believe that the deaths were the work of one individual – William Devin Howell, a drifter already in jail for the death of Nilsa Arizmendia, who was last seen getting into a van in 2003. Her blood was later discovered in Howell's 1985 Ford Econoline that he allegedly called his "murder mobile." It's there that he allegedly slept next to the body of at least one of his victims. Police were lead to Howell after his cellmate told them about his "garden" where he buried his victims who all disappeared in 2003, when Howell was working odd jobs in the New Britain, Connecticut area. Howell pleaded guilty to the manslaughter of Arizmendia in 2007, and is currently serving 15 years in prison. The trial for the six other murders may not happen until sometime in 2018, as the state continues to process the gruesome evidence.
