Westerly -- A Ledyard man was shot to death here Saturday afternoon and police are seeking his cousin, a Norwich man, in connection with the shooting.

Westerly police said officers responded at 3:58 p.m. to 11B Marriot Ave. to find a man with an apparent gunshot wound to the chest. The victim was identified as Vincent Sebastian, 28, of Fanning Road in Ledyard.

After unsuccessful attempts to revive Sebastian, he was pronounced dead at the scene, Westerly Police Chief Shawn Lacey said in a statement.

After speaking to witnesses at the scene, police issued a bulletin to departments in Connecticut to “be on the lookout” for the suspect, 31-year-old Louis Seignious Jr., with a last known address was 229 Boswell Ave. in Norwich. Police said Seignious has a child with the female resident living at the scene of the shooting.

On Saturday night Mashantucket police pursued the vehicle that Seignious was driving. Seignious then fled from the vehicle into a wooded area in Ledyard. Police from several departments and a K9 team converged on the area of Shewville Road and Coachman Pike but were unable to find Seignious, who is considered armed and dangerous. Westerly police continue their investigation.

Both Sebastian and Seignious were convicted for their roles in armed home invasions in Montville and Ledyard in 2011. Seignious, additionally charged in a burglary at the Mashantucket Community Center in 2010, was sentenced to five years in prison in 2014.
