A second suspect has been arrested by state police on a charge of felony murder in connection with the 2006 death of a Groton man whose body was found in a field in Ledyard near Shewville Road.

Police on Friday charged Christopher P. Vincenti, 32, of 109 Niles Road, Apt. A, New London, with one count of felony murder in the death of Anthony Hamlin, a 40-year-old father of five who was a member of the Eastern Pequot Tribal Nation. Hamlin’s naked body was found in a field near 428 Shewville Road in Ledyard.

An autopsy showed Hamlin died of blunt force trauma to the head. He was last seen near Union Station in New London on Jan. 27, 2006, when he told a family member he planned to take an 11 p.m. train to travel to Virginia to take a new job as a surveyor.

His body was discovered the next day in the Ledyard field.

Vincenti is being held on a $1 million bond and is scheduled to appear in New London Superior Court on Monday.

On Oct. 6, state police arrested Timothy P. Johnson, 32, of 495 Laurel Hill Road, Norwich on a felony murder charge in the same case. Johnson was arraigned and is being held on a $1 million bond. His next scheduled court date is Tuesday at the Part A major crimes court in New London.

State police said Vincenti was arrested at Troop E in Montville without incident.

With the anticipation of further arrests, the warrant for Johnson’s arrest was sealed. Information presented in court during his arraignment indicated Johnson cooperated with detectives from the Eastern District Major Crime Squad and provided a statement. He then was allowed to leave the Troop E barracks and later turned himself in.

Several members of Hamlin’s family attended Johnson’s arraignment and told a Day reporter they did not know Johnson and had many questions about Hamlin’s murder and plan to attend future court appearances.
