Chris Watts’ neighbor recalls chilling encounter with ‘family annihilator’ in doc: ‘It was really odd’

Colorado man Chris Watts murdered his pregnant wife Shanann and their two daughters Bella and Celeste.

"I saw him on his porch and said, ‘Good morning,’" Knox told Fox News Digital. "He turned around and looked at me like I had no business speaking to him. I thought it was really odd. It’s one thing if you’re shy, but he really gave me this look, like, ‘Why are you talking to me?’ You certainly don’t expect someone to react that way over a simple hello. But no one could have possibly anticipated what happened afterward." "I just remember them being so sweet. The little girls would always wave and say hi." "I felt very sad when Shanann’s dad had to fly all the way to Colorado just to tell people to stop harassing his family." "I constantly had to look over my shoulder and be on high alert because you never knew who could be watching."

Knox has spoken out in the new documentary on Tubi about the shocking murders involving the Watts family, "Suburban Nightmare: Chris Watts." It takes a closer look at the seemingly doting father who later became what experts have described as a "family annihilator." It features new interviews with investigators and others who are closely associated with the case that rocked Frederick, Colorado.
