LE, in both Abigail/Libby and Lyric /Lizzie murder cases, know the cause of death and the killers MO in the two cases,
and thereby probably have a very good idea about the motive of the murders.
This info is absolute vital info when it comes to consider if the two cases are linked.
We don't know this info, but due to that LE does they by know probably know if the cases could be linked or not.
I also still believe that LE have the killers DNA in both cases, and a DNA match would of course be the ultimate evidence
of a possible connection between the two cases. And if no DNA match, evidence that the cases probably are not connected.
Carroll County Sheriff Tobe Leazenby, who is in change with the Delphi case, clarified his on-air comments from a Thursday interview during a Fox59 report, noting
he didn't intend to confirm or deny that investigators collected DNA evidence in the double homicide investigation of Abby Williams and Liberty German.
So the fact, IMHO, is that Carroll County Sheriff Tobe Leazenby, in order to protect the investigation, just does not want anyone outside LE to know wether they have the killers DNA or not, especially not the killer.
Here is more on the DNA issue:
