PLATTSBURGH — The man suspected of killing Darcy R. Manor is also a suspect in the murders of two gay men in the Halifax area.

Glen D. Race, 26, was apprehended in Texas near the Mexican border. In his possession was the .44-caliber rifle stolen from the secluded camp on Drown Road in Mooers, where Manor was found murdered early Friday morning.

Manor’s missing 1992 Ford pickup truck was located late Tuesday in the Houston area, New York State Police Bureau of Criminal Investigation Capt. Robert LaFountain confirmed Tuesday.

Canadian sources told the Press-Republican that police suspect Race, of Dartmouth, Nova Scotia, of murdering both Trevor Charles Brewster and Michael Paul Knott, who were both gay.

The body of Knott, 44, was discovered May 5; his vehicle was found secreted in the woods near Halifax Stanfield International Airport.

Trevor Charles Brewster was reported missing on May 8; his remains were found under a boardwalk in a park well-known as a spot where men cruise for gay sex, according a Halifax newspaper, The Daily News.

His car, a black 2004 Honda Civic with a distinctive rainbow teddy bear decal on the trunk, had not yet been recovered as of Wednesday morning.

Police didn’t reveal how the men died but said there were enough similarities to merit a joint investigation by Halifax and other law-enforcement agencies.

As of Wednesday morning, Race had not yet been charged with the Mooers homicide, LaFountain said. He was arrested on several federal charges, however.

LaFountain said New York State Police were in Quebec Tuesday following leads to determine Race’s path to Mooers while other officers headed to the Houston area to bring back Manor’s truck, which had been secured by authorities there.

Manor, 35, and a married father of two young sons, was part-time caretaker at Churubusco Lodge camp where he met his death.

He’d closed his auto-repair shop just after 5 p.m. on Thursday and gone to the camp to do some work on the water system.

Friends and family looked for him after he failed to return home by his children’s bedtime; his body was found at the camp just after midnight. He had been shot.

“The senseless killing of this poor man is enough to rip you apart,” said Martin V. Lavin, the Burlington attorney whose family corporation, Churubusco Lodge Inc., owns the 395.6-acre camp property.

Wednesday, he followed Internet media reports that connected Race with the two Halifax-area murders.
