Thanks, I don’t know what happened with my previous post.
If they don’t know much about the car or who was driving it then how can they know that the driver “was able to get around quickly on the day the girls were killed, and seemed to know the area”?
I’m just wondering what there reference points for that statement could be. Getting around quickly on the day suggests they know of this vehicles movements in different places at various times.
Either his phone was pinging in different places, indicating movements. Or else, he started out early in one town and got to Delphi rather soon. Then, moved somewhere else, to establish the alibi, then back. Maybe he was seen at different places in very short periods of time, so it is hard to prove that he, indeed, was at MHB at 2-2:30. Someone might have seen him in the area at 8 AM, but at 1, he was in the adjacent city, and then at 3, somewhere else. I think the person, whether unknown or known to LE, intended to be seen, but in places unrelated to Delphi; maybe he even bought something on his way.
Another possibility - I am always thinking of people who come to expositions. There might have been some around Delphi, or else, someone living in/close to Delphi, established an alibi by allegedly being at some fair with his products. He could have returned to Delphi, killed the girls, and rapidly returned back, so his coworkers confirmed that he was “in the booth all the time”. (Such an alibi would be super difficult to shake, btw, because often the customers don’t look at the time, or don’t remember the situation very well, with lots of people around and no one checking who takes bathroom breaks, and when). It is also a possibility, I am not totally sure that the “alibi provider” is a relative/spouse. Maybe a devoted employee.
However, such situations, with the alibi and all, imply preplanning, and it would hint at the girls being targeted, specifically. Not a random hit.
