text: I get a lot of email from the friends and family of murder victims, due to my book about the NYPD’s cold case squad, and the blog I maintain specifically to help people (and to try to sell books too, of course). They ask for help, I tell them what to do and most of the time I never hear from them again. I wonder how they made out, but I realized I already know.
  When I was working on my book I studied the numbers very carefully, had a statistician check my work and wrote the following: “An unsolved murder has up to 5 – 10% chance of being cleared within one year after it goes cold. After two years, that chance decreases to less than 1%.”
  So the chances are that all those people who have contacted me over the past six years still don’t have any more answers than they did when they first wrote me.
