MATTAPOISETT, Mass. (AP) – A man described as a “person of interest” in a double slaying in the Canadian province of New Brunswick has been taken into custody in Massachusetts.

Police said Gregory Allen Depres, 22, was arrested late Tuesday night on Route 6 in Mattapoisett. He was arraigned Wednesday in Wareham District Court on a charge of being a fugitive from justice and was being held without bail at the Plymouth County House of Correction.

Further details of his arrest were not disclosed.

Depres entered the United States through Calais, Maine, where custom offficials confiscated a hatchet and several knives before allowing him to continue. He is being held in connection with an investigation into the deaths of two people in Minto, New Bruswick, a small town about 28 miles east of Fredericton, the provincial capital.

Canadian news outlets identified the victims as Fred Fulton, 74, and his common-law wife Verna Decare. Fulton was known in the area as a popular country musician.

The Royal Canadian Mounted Police declined to identify the victims, how they died or the apparent motive for the killings.

Janet Rapaport, a spokeswoman for the U.S. Customs and Border Protection Agency, said customs agents stopped a man on foot Monday while carrying knives, protective spray, brass knuckles and a chainsaw. He was also wearing a bullet-proof vest.

“He is a Canadian-born naturalized U.S. citizen. So that is why we could not deny him entry to the states. And the reason we didn’t detain him was that he hadn’t commited any violations of law. He hadn’t done anything illegal,” she told the New Brunswick Telegraph-Journal. “We did seize the weapons.”

Depres is expected to next appear in court on May 31.
