Were the killer(s) ever found for any/all of these three women? Were any suspects ever announced or even mentioned?
I've not found the cases on any of the cold case listings in the area, and there's very little about them on the web. I obtained a Washington Post article which had a picture of Mrs. Kalberer, and mentioned her estranged husband worked for the NHI.
It sounds like the FBI was involved in the search for Donna Sue Oglesby's killer (if this is the same woman), but I've not been able to find anything indicating resolution.
I came across these cases while looking for information - and specifically a picture which I've yet to find - of a Montgomery Co, MD man who was active in the area off and on through the 1970s/1980s. Looking at his case he may have been in prison when the murders took place - or if he wasn't, he was shortly afterwards. I've not found the exact date he was sent away, so am backtracking from six months served info, and if his release month is correct (and it seems to be), these murders seem to have happened before he went away.
But the little I've found indicates these women were NOT raped -- which probably rules him out. Regardless, it would seem the MCPD would have looked at him...
So I'm curious if any of these cases were solved.
TYIA!
