of the victims was dismembered. there's a lot of differences here. i have to change. originally i thought there was one killer. now i'm thinking that's not the case. >> you think it's a coincidence, because it's a remote, isolated area that it's a coincidence that a lot of bodies have been dumped there? >> i think it could be that. if you go down this area, it's deserted and it's a perfect place to drop a package off and not be seen and escape the area. >> some of these bodies have apparently been there for quite some time. >> it is, and it's difficult to establish the post mortem interval and say how long this has been going on. one of the victims was missing for at least four years. so that's a time that we can say for sure it's been four years. >> if you only have partial remains, i guess dental records -- >> fractures of bones, one way to identify. but dna is the tried and true way. i think they need to have close relatives of the missing
