What did RL know that we don't? There is no way a guy decides that "oh crap! Two kids are missing in my area, and I have a criminal record, so I better get an alibi together!" before they're even found, let alone found dead on his property!!Reading the search warrant, this is my speculation:
In the early weeks of the case, RL was a viable POI given where the girls were found, and his history and evasiveness. The warrant was written in a way that utilized the facts at hand but emphasized just those that would make RL look like a possible suspect.
My guess is that LE’s theory at the time was that RL and the Klines were collaborating and/or that they suspected RL of photographing the scene.
After the search and subsequent investigation, LE decided that RL was not directly involved with the deaths.
IMHO, RL is certainly a creep. Probably with some things to hide. But his offenses don’t include these killings. Mid-70s isn’t the age at which an offender commits a first-time double-homicide of children with ‘odd signatures’ and a complex crime scene. I also speculate that if he was collaborating with the Klines, he would not allow the crime to take place on his property.
One fact that’s troubling is RL trying to manufacture an alibi. It doesn’t quite fit with my theory. My best explanation is that he distrusted LE given his background, had some (unrelated) things to hide, and tried to manufacture the alibi to simply avoid scrutiny.
I also agree with an earlier poster (forgive me for not remembering who!) that if RL was the killer, this case would have been solved within the first year.
So what did he know that we don't? RL may not have been the killer, or involved at all. Was someone looking to frame him? Did someone taunt him with evidence of what they'd done before the girls were found by searchers? What happened that RL needed an alibi for the specific time when the girls went missing to when he called his cousin to alibi him?? I'm not buying that this guy didn't know anything about the murders. Are you?
