History

Historical Context

In August 2018, Christopher Lee Watts murdered his pregnant wife Shanann and their two daughters in Frederick, Colorado, pleading guilty and receiving five life sentences plus extra years. The killings, tied to a $1.5 million life-insurance fraud and a 2015 bankruptcy, echo financially motivated family murders such as those by John List and Bradford Bishop, fueling debate over warning-sign systems and firearm restrictions.
