I posted in reference to this car theory yesterday, but it keeps being mentioned so I can’t refrain from adding some additional thoughts. My opinion, of course.
It is indeed true that if a phone is tracking steps, that will cease when riding in a car. But that is irrelevant here.
The notion of them being driven anywhere makes no sense IMO and is totally devoid of evidence.
If I were a juror on this case, I would be compelled to determine what is beyond a reasonable doubt.
It is for me completely doubtful that someone would first drive the intended victims away from the scene and then instead of killing them far away, bring them right back to the place where their families expected them to be, where Libby’s sister dropped them off and where people would first start searching for them when they were missing.
We know they died where they were found since that is where the evidence showed they bled out.
Is there evidence of tire tracks leading to and from the murder site? Why would a murderer, having driven them away, not only dispose of them where they were most likely to be found and also plant the phone instead of throwing it 100 miles away?
To me this is as likely as saying a helicopter or an airplane or a hot air balloon was implemented to whisk them away and then incredibly brought them back to kill them and leave them in the area where they were known to have been.
If I were inclined to cold-bloodily assault and murder two beautiful young girls, I would hope to not be so blatantly ignorant as to drive them away just to bring them back, when instead I could have driven their bodies hundreds of miles away to another state, or buried them elsewhere, or thrown them into a body of water.
Certainly just my opinion.
