Sean Michael Lannon, man linked to five murders, admits to killing 16 people

A man suspected in the deaths of his ex-wife and four others -- including a South Jersey resident -- has shocked authorities by confessing that he’s killed 16 people in all.

Sean Michael Lannon, 47, who was arrested by U.S. Marshals earlier this month after a multi-state manhunt, admitted to New Jersey investigators that his alleged killing spree included "11 drug dealers," NJ.com reported.

Assistant Gloucester County Prosecutor Alec Gutierrez said in court Friday that Lannon "admitted to killing a total of 16 people."

"Fifteen being in New Mexico and one in the state of New Jersey," Gutierrez said, according to the news site. "It’s my understanding that the FBI is assisting New Mexico in their investigation."
