Chris Watts methodically murdered his pregnant wife Shanann and two young daughters in 2018, yet displayed chilling nonchalance with police—texting, enrolling them out of daycare while they were missing, and confessing only when threatened with execution. His calculated coldness, evident through body camera footage and interrogations, reveals a psychopath who disengaged from his family after meeting his mistress. Chris Watts failed a polygraph exam by nearly five times the threshold for deception, scoring negative 18 when negative 4 indicates a liar, exposing his fabricated story that his wife killed their daughters.
