The letter reportedly had new information regarding the circumstances of Dunphy's shooting, but police said Monday the investigation into its origins and content turned up nothing to corroborate it.

"Officers conducted a number of interviews as well as forensic analysis as part of their investigation," reads a statement from Laura Hepditch, the RCMP's director of communications for Newfoundland and Labrador.
