H: Uh, he could be, you know, that's, again, just kind of our theory or speculation, we have no evidence that he's done it again. But we do keep that in mind. We do check with other states to see if they have anything close; and obviously the case in Iowa is the closest; but they don't even know the cause of death in that one because they didn't find the victims until later. So, it's hard to compare. But it is similar, but, so, we have taken that into consideration as well, and we have investigated that. We've been in contact with Iowa and they have been in contact with us, and we've discussed that, but nothing else seems to be popping up around the nation that is similar to this. But that doesn't mean he is gonna kill everybody the same way every time, so (shrugs), we don't know.
