On March 10, 1983, housewife and mother Dorka Lisker was attacked in her home by an intruder. She was bludgeoned and stabbed, leaving her mortally wounded. Her son, Bruce, who she was expecting to come over to borrow some tools would be the one to stumble on the horrific scene. But instead of being treated as the grieving son, he quickly became the prime suspect. And the investigators on the case would do what they needed to do to make sure the case they were building against him would stick, no matter what it took.
