Fingerprints have me baffled, too. And to add to that, if LE does have them are they full or partial - that is, not enough for an identifiable match? I don't know how complete a print they can get off one of the victims unless it is some smooth area such as smooth leather, vinyl or plastic.Usable fingerprints from an outside crime scene where victims were exposed to overnight winter temps is interesting. I've read lifting fingerprints from skin and fabrics is possible but difficult and it's nearly impossible with organic materials such as leaves or branches etc.
No other audio capturing the killer's voice except those 4 words is unfortunate to hear. With no more audio I would think trying to match it to any suspect couldn't be very accurately done.
LE doesn't factually know the route the Delphi killer took leaving an the outdoor crime scene. I'm guessing there was too much ground cover, fallen leaves to track a man's path and killer didn't leave any trail of blood because he didn't get much on his person?
Stilling executing search warrants 4 years later stumps me but good as to what the heck they could be telling a judge they're looking for or why they think they have a probable cause of finding it. I'd really love to hear what everyone thinks about this one
Thanks for all this info, very thought provoking in many areas!
As far as LE knowing the route, I can't recall if LE brought out dogs. Of course, I'm not a SAR expert so I don't if it is possible to track from a scene without giving the dog an article from the person they want tracked. (Given all the personnel - searchers, LE, crime scene techs, medical examiner - in the area going to and from the crime scene I imagine the dog would be unable to discern one scent from another without some article from the person to be tracked.) With all the ground cover from fallen leaves I doubt LE could find shoe prints from the crime scene to track the killer's path out. (I imagine they MIGHT have shoe prints on the creek bank which could reveal a shoe type and size. Assuming they could discern them from LE and searchers in the area.) Having tracked a mortally wounded large animal (deer) multiple times the blood trail is minimal, sometimes even if the animal is not running. So without a serious injury to the killer, I can't see a blood trail being a strong possibility.
Probably cause justification to a judge? If person identified in a tip throws away something like straw, cup or other possible DNA source and it matches the crime DNA then that might be cause for a warrant to get a sample direct from the person. Another might be from preliminary shoe print match, like on the ground around the suspects place of work. I don't know how much weight a judge would allow for information from someone who claimed to hear an admission or bragging about the murder from another person.
