It's the dramatic moment cops confronted Nichol Kessinger, the girlfriend of Chris Watts, who murdered his pregnant wife and two daughters to start a new life with her. Watts was sentenced to three consecutive life terms earlier this month. Newly released video shows Kessinger being interrogated. She breaks down sobbing over the gruesome fate of the children: 4-year-old Bella and 3-year-old Celeste. Other videos reveal the web of lies and deceit Watts created in a story that shocked the world.
