A man wanted for questioning in connection to five murders in two states was arrested hundreds of miles from where the alleged crimes happened. 

Police were searching for Sean Lannon of Grants, New Mexico, to ask him about a homicide in New Jersey and a quadruple killing in New Mexico. On March 10, the Gloucester County Prosecutor's Office announced Lannon was arrested in St. Louis.

On March 8, Lannon allegedly forced his way into a home in Elk Township, New Jersey, and was charged with burglary and possession of a weapon, television station WLNY reported.

Lannon, 47, was identified as a person of interest after a male acquaintance in his 60s in Greenwich Township, where Lannon reportedly has roots, was killed the same day, according to The Philadelphia Inquirer.

Lannon was also wanted for questioning in New Mexico, where the bodies of his ex-wife, Jennifer Lannon, 39, and three men, Matthew Miller, 21, Jesten Mata, 40, and Randal Apostalon, 60, were found inside a car at an Albuquerque parking garage on March 5.

According to law enforcement officials, three of the four victims — Jennifer Lannon, Miller and Mata — all vanished around the same time in January from Grants, a town almost 80 miles away.

Albuquerque police told television station KOAT that “the bodies were found in various states of decomposition.”

“There’s a lot of aspects to this. We’re still finding out information as we’re going forward with this investigation,” Grants police Lt. David Chavez said. “There are some things we cannot release at this time.”

On Tuesday, the Gloucester County Prosecutor asked for help finding Lannon and listed him as armed and dangerous. 

Hours later, the agency announced his arrest on Wednesday morning in Missouri. 

"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 announcing the arrest. 

Hoffman said she plans to charge Lannon with homicide in connection to the New Jersey killing.

Police in New Jersey say there may still be witnesses who can provide information about their case and ask anyone with knowledge to call (856) 498-6238.
