The summer of 2018 should have been a joyous one for the Watts family. Husband Chris Watts, then 33, and wife Shan’ann, 34, just found out they were expecting a son to join 4-year-old Bella and 3-year-old Celeste in their suburban home of Frederick, Colorado, about 27 miles north of Denver.

As the family balanced Chris’ job as an operator at Anadarko Petroleum and Shan’ann’s frequent business travels for the nutrition supplement company Le-Vel, their lives centered around their daughters, as shown in Shan’ann’s frequent Facebook posts.

From the outside, they appeared to be a happy suburban family, but Shan’ann’s friends had recently started hearing about trouble in paradise. Still, no one could have ever guessed the chillingly brutal murders that were about to put an end to their happily ever after. Here’s how it unfolded:
