I can't imagine the mental and physical toll it takes on a person to solve cold cases, any murder case really, no matter how long ago it was. To sacrifice so much of your time and family to try and bring closure and peace to other families who lost loved ones is a hero in my eyes. I hope he can find his own peace and happiness. I find these cases intruiging, but I can never handle something like this. I think it takes a strong person to work on such brutal cases. Not all heroes wear capes.
