From the Buffalo News:
North Tonawanda police Tuesday said that a body pulled from Canadian side of the Niagara River this weekend has been positively identified as Douglas Vaillancourt, a 23-year-old North Tonawanda man who was reported missing last week when he failed to report to his job at the Niagara Falls Post Office.
North Tonawanda Police Capt. Thomas Krantz said the body was recovered Saturday and dental records were provided.
“There was no evidence to suggest any foul play,” Krantz said.
