This show is actually quite graphic in regards to showing the actual bodies of victims, etc. The real time interviews with witnesses, family, potential killers, is truly riveting. It literally keeps me on the edge of my seat. The program airs at all hours of the day, the schedule can be found at this link here.
Other reality crime shows that are also awesome include Cold Case Files and Forensic Files, which both happen to air on A&E. 48 Hour Mystery, which airs on CBS on Saturday nights at 10p.m., is more of a dramatic/story telling program on missing persons, mysterious deaths, etc. If you're interested in crime scene and mystery programs, you can't do wrong with any of the four I mentioned.
