ALBUQUERQUE, N.M. >> A man sought in the killings of four people in New Mexico and one in New Jersey was arrested this morning in St. Louis, the U.S. Marshals Service said.

Investigators were seeking Sean Lannon in connection with a slaying Monday in southern New Jersey. The 47-year-old also is a person of interest in the deaths of his ex-wife and three men whose bodies were found last week in a vehicle at an Albuquerque, New Mexico airport garage.

Albuquerque police said they will travel to St. Louis to interview Lannon about the New Mexico deaths.

Authorities considered Lannon armed and dangerous, and the marshals service had offered a $5,000 reward for information leading to his arrest. The Gloucester County prosecutor’s office had said Lannon may have been driving a 2018 blue Honda CRV and was possibly seen Monday afternoon in Camden, New Jersey.

Authorities didn’t immediately offer details on what led them to Lannon today.

Lannon was charged with burglary and possession of a weapon after allegedly forcing entry into a home Monday in Elk Township, New Jersey, about 20 miles south of Philadelphia, the prosecutor’s office said. It was not clear today if Lannon had an attorney.

He is also a suspect in a killing on Monday in East Greenwich, New Jersey, about 12 miles north of the site of the alleged burglary. Acting Gloucester County Prosecutor Christine Hoffman said today upgraded charges would be filed against Lannon.

Lannon also is a person of interest in the deaths of his ex-wife and three men whose bodies were found last week in a vehicle at the Albuquerque International Sunport garage, police said.

Albuquerque police said three of the people were reported missing since January from Grants, about 80 miles west of the city.

Authorities have said that the bodies of Jennifer Lannon, 39, Matthew Miller, 21, Jesten Mata, 40, and Randal Apostalon, 60, were found inside a car parked on the top level of the garage on Friday. The cause of death wasn’t immediately clear.

According to Grants Police, Jennifer Lannon, Miller and Mata were friends, and Apostalon lived out of his car and was known to give rides for money. The bodies were found in Apostalon’s car.

Police had posted on Facebook last month that they were seeking a different suspect in connection with the disappearances of Jennifer Lannon, Miller and Mata. Authorities did not offer further information about that potential suspect today.

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

Property records show Lannon’s most recent address is in Grants, with numerous addresses in southern New Jersey prior to 2020. The couple filed for bankruptcy in federal court in New Jersey in 2015 and listed personal property assets of roughly $14,000 and liabilities of more than $550,000, including $83,000 in student loan debt.
