Police hope new clue can crack Erin Gilmour, Susan Tice cold cases

Toronto police are hoping a new piece of evidence might finally help them find the sexual predator who killed Erin Gilmour and Susan Tice.

Both murders have remained unsolved since 1983, when both women were found dead in their apartments months apart. Until now, police had said Gilmour and Tice’s lives never crossed. But a tip received by police indicated both women frequented bars and restaurants in the Yorkville area, where they may have met their killer.

Det. Sgt. Steve Ryan of the homicide unit called it a “significant” lead and are appealing to the public for any more information they may have relating to it.

The CBC’s Sue Sgambati has more on the latest development in the cold case in the video above, including a major reward being put forward by Gilmour’s family.
