A decades-old murder in Los Angeles was eventually cracked after DNA evidence pointed investigators towards an LAPD officer who had once been romantically involved with the victim's husband. More than 20 years after Sherri Rasmussen was killed, Stephanie Lazarus was convicted of her murder.
Meanwhile, in Massachusetts, jurors in Lindsay Clancy's murder trial are facing a very different question as they struggle to reach a unanimous verdict over the deaths of her three children. Her defence says she was suffering from postpartum psychosis, while prosecutors argue that she understood her actions were wrong.
