U.S. Marshals apprehended Lannon, who Hoffman described as "clearly a direct threat to the public."

Police said Dabkowski died from blunt force trauma at his East Greenwich Township home on March 8. Lannon was charged with multiple offenses in connection to Dabkowski's death, including murder, burglary, murder during commission of a robbery, murder during commission of a burglary, robbery, possession of a weapon, possession of a weapon for an unlawful purpose, possession of a blunt object for unlawful purpose and theft of motor vehicle.

Neighbors of Dabkowski told NBC10 he was always willing to lend a hand and will be sorely missed.

"I've been here 20 something years. He's always been nice to me," one neighbor said of Dabkowski.

Despite the arrest, the investigation remains active. Anyone with further information on the murders or Lannon should call Sgt. John Petroski of the Gloucester County Prosecutor's Office at 856-498-6238.
