It's hard to walk away from a case. I don't look at it as giving up of the victims, though , I look at it in terms of where my energies could be better spent. We have some many UID's that still don't have their names, their entire life histories back. So many parents, sister, brothers, friends wondering what ever became of their loved ones. There is so much work to be done on WS, when one case hit a wall, I just move on and try to help somewhere else.
