If I recall (?), DPCSO collected hair samples from Debbie's mother years ago. If they don't have anything on LS, they could EASILY get it if: 1) someone cared enough about Debbie's case, and 2) they'd get off their hands. Other law enforcement departments are doing it across the country. Just recently, 2(?) detectives retrieved a cigarette butt from one of the EL tracks (Chicago), and within a short time were able to make an arrest. I don't remember who, or the specifics. WTF!! Unfortunately, LS probably doesn't even leave his house if he's still alive. I think he still has 1 or 2 siblings that are still alive(?), along with 3-4 children of his own. Obviously, any DNA would have hadto have been found on Debbie's body. At one time, consideration was given to exhuming Debbie's body (check below fingernails?), but permission would have to be given. With both of her parents gone, I have no idea how that works. Would the permission have to be given by a living relative? I think Debbie has 4 siblings that are living - not sure where. Easy enough for DPCSO to figure out in less than 20 minutes.
