The Houston police department defines a cold case as “when all probative investigative leads available to the primary investigators are exhausted and the case remains open and unsolved after a period of three years.”  The word probative means “affording the proof of evidence” when there is no evidence the case must remain open or they will close the case so it’ll remain it as a “cold case”.
