Victor Morales is found dead in a motel parking lot. His death is a complete mystery and his autopsy proves to be one of the most unusual she’s ever seen. Keith Douglas was brutally shot to death and it’s up to Dr. G to find the hard evidence to bring his killers to justice.

The victim had been stabbed more than a hundred times; her bedroom was blood-soaked. While her body was positioned in a suggestive way, she hadn’t been sexually assaulted. Was this a sex crime, or the random act of a man with an intense hatred of women?

Florida v. Dayonte Resiles. 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.

Can the sound of a suspect’s voice reveal his lie? Can the crucial moment of crime, buried deep in damaged video, be revealed? Can computers isolate a guilty face in a crowd? No longer science fiction, these are the high-tech tools of the forensics trade.
