I would say that is an excellent cause you have going.

There's one unsolved that particularly gives me nightmares. 2 young girls in Delphi, Indiana killed for no reason in a park in broad daylight. It makes me sick. I look online for any updates all the time. Nothing. Not only that but one girl left her phone on and also had pictures on it. So they have a pic and his voice! Still no leads?

If you can help solve one of these kinds of cases you've done a wonderful thing.
