A cold hit in CODIS is really what you live for in CODIS. It is where you put a DNA profile into the the database and it matches something; it either will match another case an unknown sample from another case or it could match an offender or a RSD sample in there. Cold hits right now are a really big concern. Obviously technology has advanced to the point that we're identifying more suspects off pieces of evidence from cases in the past. I think it's critical that agencies put policies and procedures in place to identify how they're going to handle those hits and also address the resource issue; you're going to need resources down the road when these hits start coming into your investigative units, so you need to plan in advance put a policy in place and have the resources available. I think it's very important anytime you've asked an entity that's involved in this criminal justice system to perform work for you, maybe it's on an old rape case, maybe you're working through a rape backlog, and you submit all this work to the lab when the lab does that work and they issue these letters telling you the results of those and maybe it's a hit letter or a lead, you know those need to be aggressively followed up on.
