Thanks. I remember that video, the touch DNA on the sweatshirt, only a partial DNA and the issues with the DNA. Right off, though, I only remember one thing he said about the DNA that was later corroborated by LE. That was the fact that LE wasn't sure if they had the killer's DNA and that came out this last February when Sheriff Tobe Leazenby acknowledged that fact to HLN in an interview. I still question the validity of the info though. In my background as an auditor, testimonial evidence is the lowest form of evidence. So low, in fact, that it can not be used as evidence in an audit report unless it is corroborated by other stronger, non-testimonial evidence. So that is really my take on it from where I'm coming from.
The caller's take on how long he was in the area is interesting and I wonder what he is basing it on or the reliability of his source. (Remember in that same HLN interview with Sheriff Leazenby, he states they do not know the path of the killer from the crime scene. So does LE even have a handle on the timeline?) If the girls encountered the killer between 2:15 and 2:30 (from FBI billboards early on) the path from the bridge, down the hill and to the crime scene could have been covered in 15-20 minutes. If the murders happened fairly quick - and I believe they did - this killer could have started his exit from the crime scene 10-20 minutes before Liberty's father arrived (3:11). It is possible that by 3:30 this killer could be on the road exiting the Delphi area. Of course, he could have taken his time leaving the area. I just believe he left as quickly as he could without being seen.
What I do find interesting is about 2:10 in the video, the caller speculates the killer was visiting someone nearby and committed the murders. One of my strongest scenarios from very early on has been a variation of that scenario. The weakness I find with the caller's scenario is that if the killer was visiting a resident, then someone in the area might at least remember the face from somewhere in town. I believe the killer had, sometime in the past, BEEN - past tense - a visitor or even a resident. Perhaps as a middle school student. I know when I had an older relative in the mid-west, I ventured not only all over the property, but crossed numerous fences and became familiar with a large part of that county. (Yeah, I was trespassing, but to the best of my knowledge I was never seen, let alone caught.) Had I gone back there 10-15 years later I could have continued over that same area. And if I did return I seriously doubt if anyone would have recognized me as the 12-15 yo kid who used to stay with persons who had been deceased for about 8-10 years. And the area I'm talking about in the mid-west is probably 5-10 times larger than the Delphi trail and adjacent property. Still it is interesting to hear someone on a GH video or another video or podcast toss out a similar scenario.
