PLATTSBURGH, N.Y. - A Nova Scotia man pleaded not guilty to murdering a man at a remote hunting camp in upper New York state, an American prosecutor said Tuesday.

District attorney Andrew Wylie said Glen Race entered pleas on seven counts, including first- and second-degree murder in the death of Darcy Manor of Mooers, N.Y., on May 10.

"He entered a plea of not guilty to each charge,'' Wylie said in an interview following the brief court hearing. "Our office asked for Mr. Race to be remanded without bail. The court granted that application.''

Race is also charged with burglary and grand larceny in connection to several of Manor's possessions.

If convicted, he could be sentenced to life without parole.

Race, 26, entered Clinton County court with his eyes closed and sat quietly with his eyes squeezed shut as the charges were read and his court-appointed lawyer entered the pleas.

Race is also charged in the first-degree murder of Trevor Charles Brewster, 45, and Michael Paul Knott, 44 -- two gay men from Nova Scotia whose bodies were found in the Halifax area in the first week of May.

On May 10, police allege Race stole Manor's credit card, pickup truck and a rifle from the property where the victim was found.

Manor, a 35-year-old father of two, was shot to death at a secluded hunting lodge that he was taking care of. Police later discovered Manor's truck, which had been missing, in Houston.

Race, who grew up around Halifax, was arrested May 15 by U.S. border patrol officers near the Mexican border.

Wylie said it's expected the defence counsel will ask that a psychologist evaluate Race to determine if he's fit to stand trial. An earlier assessment by a court-appointed specialist found he was fit to proceed to Tuesday's hearing.

The next hearing is scheduled for Oct. 31.
