The Watts family murders occurred in Frederick, Colorado, United States, during the early morning hours of August 13, 2018. Christopher Lee Watts (born May 16, 1985)[1] admitted to murdering his pregnant wife Shanann Cathryn Watts (née Rzucek; born January 10, 1984) by strangulation. He later admitted to killing their daughters, four-year-old Bella and three-year-old Celeste, by smothering them with a blanket over their heads. On November 6, 2018, Watts pleaded guilty to multiple counts of first-degree murder as part of a plea deal when the death penalty (which was later abolished in Colorado in 2020) was removed from sentencing. He was sentenced to five life sentences without the possibility of parole, three to be served consecutively.
