An heir to the Halliburton oil dynasty fortune, Jill Halliburton Su was found dead in her bathtub by her son Justin at her upscale home in a Davie, FL, gated community in 2014. The security cameras weren't working, a glass door had been shattered, and at least one room of the house had been ransacked. Police quickly focused on Justin as the prime suspect, grilling him intensely for hours. A few days later, when crime scene DNA forensic tests were finally processed, Justin was cleared; and investigators were after a new suspect.
