Paul Bernardo and Karla Homolka’s wedding day was a lavish affair, horse-drawn carriage and all. While their guests toasted to the happy couple’s new life together, fishermen and boaters on Lake Gibson were making a gruesome discovery: human remains encased in cement…10 pieces in all. Those remains belonged to 14-year-old Leslie Mahaffy, who had gone missing from the backyard of her family’s home. She wasn’t the first teenager to die at the hands of Paul and Karla…and she wouldn’t be the last.
