Authorities say 47-year-old Sean Lannon was arrested Wednesday morning in St. Louis, Missouri by the US Marshals Service. He was wanted for questioning in connection with the brutal death of a middle-aged man who was found dead Tuesday in a house on Myrtle Avenue in East Greenwich Township. Investigators say Lannon is familiar with that victim.
Officials believe Lannon fled to South Jersey, where he used to live, after possibly being involved in the murder of four people in Albuquerque, New Mexico. He is considered a person of interest in the quadruple murder.
Albuquerque police say the bodies of Jennifer Lannon, Sean’s ex-wife and three others – ages 21, 40 and 60 – were found on Friday in a pickup truck left in an airport parking garage.
Court documents show that Jennifer and Sean got divorced in 2019.
Lannon is also charged with breaking into a building on Monday in Monroeville, Elk Township, while armed with a knife, a day before the victim was found in East Greenwich.
Investigators also say Lannon is an ex-serviceman with a history of drug use and a record of violence.
Acting Gloucester County Prosecutor Christine Hoffman said higher charges against Lannon related to the East Greenwich Township murder are forthcoming.
