Several Nova Scotia RCMP officers engaged in sex parties, used drugs, and misused their weapons, according to an anonymous letter that surfaced at a Nova Scotia Police Review Board hearing yesterday. Ambrose Heighton, the former police chief of the Town of Stellarton, was fired two years ago and is appealing his dismissal, which he says was due to his complaints about the RCMP of Pictou County. The letter in question was submitted as evidence, and it lists the graphic details of a party, which included several RCMP officers using cocaine and receiving oral sex from one of the officers’ wives. The letter also alleges that an RCMP officer carried and dropped his pistol while jogging off-duty. The unproven allegations also state that the RCMP district commander staff sergeant at the time, Ross Landry, knew of these claims and did not respond to them. Landry, now Nova Scotia’s provincial justice minister, may testify Tuesday.
