An heir to the Halliburton oil dynasty fortune, Jill Halliburton Su was found by her son Justin dead in the bathtub at her upscale home in a Florida 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. But despite the dramatic interrogation room sessions, the son never admitted guilt. A few days later, when crime scene DNA forensic tests were finally processed, Justin was cleared; and investigators were after a new suspect. (thetvdb.com)
