They're growing as well, and I think it's approximately the same size. But for some reason California tends to have more missing individuals than other states do. I know Texas is in a similar situation. I'd have to check my records to give you those numbers.
I can tell you that from a national perspective, the way it works in the U.S. is that they have a national missing persons registry that is funded federally. That basically allows the FBI and two other laboratories to provide service to identify missing remains. Yesterday I checked with my colleague who runs this registry, and they have 4,245 missing person samples in that registry, which was established in 2000. They have about 1,195 unidentified found human remains, the origin of which they just do not know. To date, they've made seven of what I would call cold hits. That means there would be no prior understanding that this sample would match these parents, for instance. In contrast, for instance, we have what we would call a warm or a hit to assume identification, where the police have come forward, and they're pretty sure that this might be the missing individual, but for reasons of environmental insult, perhaps, there are no fingerprints, the remains are not all there, or there are different conclusive results. They have 1,100 cases, for instance, that they've processed based on what we would call conformational identification.
