Cold Case Files

The Tourniquet

It's the late 90's in Houston, Texas and a serial killer is on the loose, having already strangled at least three women to death. His signature? A ligature tied around the neck, and tightened with a tourniquet.

Based on the iconic, Emmy-nominated series on A&amp;E, this show explores some of the most difficult-to-solve murders, which stymied investigators and went cold, sometimes for decades. In fact, one-third of all murders in America remain open. But thanks to dogged investigators and breakthroughs in forensic technology, these cases become part of the rare 1% of cold cases that are ever solved. Cold Case Files is hosted by Paula Barros.
