San Diego, California
After a messy divorce and claims of "white-collar domestic violence" and "legalized emotional terrorism," Betty Broderick took matters into her own hands. In a tale retold in books and made-for-TV movies, Betty opened the door to her ex-husband's Colonial-Revival mansion in Marston Hills (using her daughter's key) on a November night in 1989, walked up to the master bedroom, and fatally shot Daniel T. Broderick and his new wife, Linda Kolkena-Broderick. Betty Broderick was convicted of second-degree murder in 1991 and sentenced to 32-years-to-life. More recently, Broderick was denied parole, with officials noting her lack of remorse. The 3,312-square-foot home was built in 1935 and, after a complete exterior makeover, sold for about $2.4 million back in 2006.
