A man wanted in connection with five homicides in two states was arrested and charged with murder Wednesday, authorities said.

Sean Lannon, 47, was wanted for questioning regarding a homicide that occurred Monday in East Greenwich, New Jersey, the Gloucester County Prosecutor's Office announced in a public bulletin Tuesday.

Lannon is also a person of interest in a quadruple homicide in Albuquerque, New Mexico, in which one of the victims was his ex-wife, authorities said.

Lannon was arrested Wednesday morning in St. Louis by members of the U.S. Marshals' St. Louis Metro Fugitive Task Force, the Gloucester County Prosecutor's Office announced.

He was found sleeping in a blue Honda CR-V that was reported stolen in connection with the East Greenwich murder, Gloucester County Prosecutor's Office spokesman Chief Thomas Gilbert told ABC News.

Lannon was charged with murder and theft of a car in connection with the East Greenwich homicide, the prosecutor's office said.

He also was charged with burglary, robbery, possession of a weapon and possession of a weapon for an unlawful purpose for a separate incident that occurred Monday in Elk Township, New Jersey, the prosecutor's office said. Lannon allegedly forced his way into a home while armed with a knife. No one was harmed, authorities said.

Prior to his arrest, authorities had warned that Lannon should be considered armed and dangerous.

"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," acting Gloucester County Prosecutor Christine Hoffman said in a statement Wednesday, noting that Lannon "was clearly a direct threat to the public."

New Jersey detectives believe there are additional witnesses who can help in the active investigation. Anyone with information is encouraged to email tips@co.gloucester.nj.us or call Sgt. John Petroski of the Gloucester County Prosecutor’s Office at 856-498-6238.
