Ledyard police search for man accused of killing cousin in Westerly

New London

LEDYARD, Conn. (WTNH)– The suspect in Saturday’s deadly shooting in Westerly, Rhode Island is still on the loose.

“It’s very difficult,” said Theo Corprew-Sebastian of Ledyard. “To have a family member taken from you at the hands of another family member.”

Corprew-Sebastian and Linda Marie Kilgore are first cousins with the 28-year-old victim Vincent Sebastian.

“My mother is the victim’s father’s twin,” explained Kilgore.

Police say Sebastian was shot by another cousin, 31-year-old Louis Seignious of Norwich, at an apartment in Westerly. These relatives say Seignious and Sebastian had often bonded and beefed with each other.

“This has been going on for years,” said Kilgore.

But what may have led to Saturday’s violence was that Sebastian was now dating the mother of Seignious’s daughter and it was in her Westerly apartment that the shooting took place.

Afterwards police say Seignious took off to Ledyard where his car was found on Shewville Road just after 5 p.m. 

“It was abandoned, still running with the door open,” said Ledyard Police Chief John Rich.

Police searched for Seignious but did not find him.

“Yes, we’re concerned that Mr. Seignious may still be armed and that he should be considered dangerous,” said Chief Rich, who also urged anyone who sees him to call 911.

Ledyard police have Seignious’s 2000 Acura TL secured at the police department. They are just awaiting search warrants. They can either get a warrant which would allow them to search the car or they can get a warrant which would allow them to turn it over to Westerly police who can then search it.

In the meantime, a plea from these cousins.

“We just ask that he turn yourself in,” said Kilgore. “That’s like to make it easier on us and him and his family.”

“The only thing that I can pray for is that this brings unity within my tribe,” said Corprew-Sebastian.

He says they are all members of the Mashantucket Pequot tribe and they do not want to lose another family member.
