A man arrested for the deaths of his ex-wife and four others has shocked authorities by confessing that he has killed 11 more. Suspect Sean Michael Lannon, 47, was arrested last week after a multi-state manhunt.

Lannon was suspected of killing his ex-wife Jennifer Lannon, 39; Matthew Miller, 21; Jesten Mata, 40; Randal Apostalon, 60; and Michael Dabkowski, 66.

During a preliminary hearing for Dabkowski's death, Lannon claimed that he killed as many as 16 people, Daily Mail reported. Dabkowski, who was beaten to death with a hammer, was found dead inside a laundry room at his home in East Greenwich, New Jersey on March 8.

Sean Michael Lannon alleged that the victim sexually abused him when he was a kid and possessed lewd photos of them together, which he tried to retrieve.

Public defender Frank Unger said that Lannon and Dabkowski's relationship turned into an abusive one, where the latter sexually abused the suspect.

"He was repeatedly sexually assaulted and during that time the victim, in this case, documented those sexual assaults, those rapes, by taking pictures of himself with Mr. Lannon in sexually compromised positions," Unger noted.

After Dabkowski attempted to seduce the suspect, Unger also claimed that he attacked Lannon first before the suspect used the hammer on him.

A judge on Friday denied Lannon's release after hearing the shocking confessions. Assistant prosecutor of Gloucester County Alec Gutierrez said that Sean Michael Lannon admitted to killing 15 people in New Mexico and one in New Jersey.

The bodies of Lannon's ex-wife, Miller, Mata, and Apostalon were found in a pickup truck abandoned at an airport on March 5. 

Lannon reportedly told a witness that he murdered his wife, along with his boyfriends in New Mexico, and then killed Dabkowski in New Jersey. The couple had three children, and they filed for a divorce in 2019, according to a Law Officer report.

Lannon was driving Dabkowski's SUV and still possessed the murder weapon when he was apprehended in St. Louis, Missouri on March 10. Investigators said Lannon has told them that he dismembered some of his victims after luring them to a home.

Grants Police Department Lt. David Chavez is not yet considering Lannon as a suspect in the 11 additional murders he has confessed to since it's still unclear who are Lannon's other victims.

Sean Michael Lannon has yet to be charged in the four deaths, making Dabkowski's murder the only charge Lannon is currently facing.

But he was also charged with burglary, possession of a weapon, and motor vehicle theft connected with Dabkowski's case. Lannon is reportedly an ex-military man with a history of drug abuse and a violent record.

Authorities urged any witnesses with information about this crime to call the Gloucester County Prosecutor's Office at 856-498-6238, ABC 6 reported.
