Acting Gloucester County Prosecutor Christine Hoffman and New Jersey United States Marshal Juan Mattos have jointly announced that Sean Lannon was arrested this morning in St. Louis, Missouri by members of the U.S. Marshal’s St. Louis Metro Fugitive Task Force.
According to county officials, Lannon was wanted for questioning in relation to a homicide that occurred on March 8, in East Greenwich. He is also considered a person of interest in a quadruple homicide that happened in New Mexico.
“The rapid and successful apprehension of Lannon is the direct result of excellent collaboration between a wide array of local, county, state and federal partners," Prosecutor Hoffman said. "We are particularly grateful to the U.S. Marshal’s New York/New Jersey Regional Fugitive Task Force/Camden Division as well as their parallel jurisdictions between New Jersey and Missouri for deploying their resources to rapidly apprehend Lannon, who was clearly a direct threat to the public.”
Prosecutor Hoffman indicates that upgraded charges against Lannon regarding the homicide in East Greenwich Township are forthcoming.
Prosecutor Hoffman also comments that “While the wide array of specific law enforcement and social service agencies involved in this investigation will become clearer moving forward, the Prosecutor and investigative staff at the GCPO are also grateful and deeply appreciative of contributions made to this ongoing investigation by members of the community and the media.”
This investigation remains active and Detectives believe there are additional witnesses who can provide crucial information to aid and further this investigation.
