While being interviewed by police, Christopher Lee Watts (born May 16, 1985, in Oklahoma) admitted to killing his pregnant wife Shannon Cathryn Watts (née Rzucek, born January 10, 1984 in New Jersey) by strangulation. Their daughters, four-year-old Bella, and three-year-old Celeste, died by asphyxiation due to smothering. He then disposed of his daughters' bodies in oil tanks and buried his wife in a shallow grave at his work-site.
