Guy Greffard

On October 13, 2022, 65-year-old Guy Greffard was arrested by the Edmonton Police Service for the July 9, 1981 rape of a 15-year-old girl in Edmonton, Alberta.

The girl was sexually assaulted by an unknown male while walking home across a school field in northeast Edmonton. The file was reopened in February of 2018 by the Historical Crimes Unit, and the RCMP Lab was able to develop a DNA profile of the suspect. There were no hits to Canada’s National DNA Data Bank. Police then turned to FGG, beginning in 2021.

There is currently no information on who conducted the FGG investigation, or how the initial confirmation as made.

Greffard was arrested in Kelvington, Saskatchewan. He is facing charges of rape and gross indecency in the Alberta Provincial Court.

The Edmonton Police Service has stated that they have used FGG on five police files thus far, including a robbery, a human remains identification, and two other sexual assaults. This is the first to result in charges. The results of the other investigations have not been made public.
