Judging by this article release in June of last year, it sounds like we might actually have a serial killer case?? Im trying to see if there is anymore information but it might be useful to look into the other three unsolved cases. Three other sex workers were found dead from strangulation in the area.
In 1993 Sophie Filion was found in Westboro, stuffed in garbage bags. She had also recently turned to sex work. In 1995 Carrie Mancuso was found strangled to death in an apartment on Lafontaine Ave. Amy Paul (a more recent case) was found dead from strangulation in a field in the rural area of south Ottawa.
Now the article suggests this connection to Melinda's murder based on the cause of death in all the cases. They were all found in different parts of the city and it could very well be different murderers but maybe looking into the similarities of these unsolved cases of 4 young woman strangled to death all working in the sex industry might offer us more clues into who killed Melinda and these woman?
