The “Ellensburg couple” info came from Keyes himself, Halla talks about it. Keyes gave vague info about the location of the murder/disposal and the female victim (but not the male for some reason).It’s unclear to me how or why the drowning/accident victim would be the first/possibly out of state victim, particulary when Agent Halla talked about drownings per year in WA state.
I know the part in the interviews where Keyes talks about Ellensburg, and east and west WA. I do not know why a couple would be attached to that? If anyone knows (actually knows, not “because Josh said so” knows), do tell!
I see your point in why FBI would want to say it’s eleven victims, even if they wouldn’t really believe it. I’ve thought about that a lot too. Did you know the average number of victims for an offender like Keyes is twelve? That made me think eleven actually is likely. Also, because Keyes said he’d run out of “stories”, and “now wished he hadn’t have restarined himself as much as he did”. It also fits with him saying “Washington is a good backup plan”. That would imply more victims in WA, than other places.
There is not really any reason to believe they are specifically connected to Ellensburg, or that they are a “couple” as such—just a male/female pair of some kind. Because he described the woman as “older” but did not state anything like this about the man, I kind of lean away from them being an actual couple.
Re: the FBI’s current victim count, it’s interesting that TCBS released something after the season ended in which they went through a similar exercise to what I did, but for a different reason. But they included a reference that I’d never heard of where Keyes apparently said something like his first murder went perfectly, so their “known” victim count was 12 instead of 11 unless that murder was in Canada.
If that’s true, that means either his first murder was before he got out of the army (in contrast to what the FBI thinks) or my theory that the accident victim was the first one post-army is wrong.
