Police said, five years ago, that they were “tantalizingly close” to solving the murders of two women killed in Toronto decades ago, but the 30th anniversary of those deaths is at hand and the killings remain unsolved. Susan Tice, 45, (inset), a former Calgary resident who had moved to Toronto just before she was slain, and Erin Gilmour, 22, were killed four months apart, by the same perpetrator, police believe. Toronto Police have a video, photos and details of the crimes on their cold case web page. Police used DNA testing to link the murders. The link, and the failure of investigators to close these cases, raises the troubling possibility that a serial killer was never caught and could still be stalking and killing women.
