I still think somewhere herein lies a potential clue. This killer did more than just murder these girls. He left things at the scene. It appears he may have purposely placed things at the scene, things that we would not normally expect. In fact, it appears some of the items left at the scene were intended to lead LE down the wrong path, and likely did just that for 2 years.
"Now, Ives reveals that the crime scene was nothing like murders he had encountered in the past, where typically a body is found with some evidence such as shell casings present.
'There was a lot more physical evidence than that at the crime scene,' Ives said. 'And it's probably not what you would imagine, or what people would think I'm talking about.'
'It was just not your normal "a person was killed here" crime scene, that's probably all I can say about it,' Ives said.
Ives said that the scene was 'odd' and displayed at least three 'signatures', which are unique behaviors by the killer.
However, Ives raised the possibility that elements of the scene had been staged in an attempt to trick investigators by sending them down a false path."
