The Woman in the Woods

Nick and Mindi Kassotis believed they were being hunted. According to friends and family, Nick's classified military work had put them both in danger, so much so that Mindi rarely left the house.

But the couple also shared they were expecting a child. Then, just after Thanksgiving, Mindi died suddenly in the hospital.

Soon after, Nick died too. That's what everyone who loved them believed, that is until a woman's dismembered remains turned up in a wooded area.

Stories started to unravel and a mysterious new figure emerged. "48 Hours" correspondent Erin Moriarty separates fact from fiction in a case built upon unimaginable layers of deception.
