Also she was streaming video , so LE would know that they were killed because they saw something , I don't see that as something they would have to keep quiet
I don't think she was streaming, someone said there was no connection on the bridge. I don't know what else was on that video.
We have two groups here, one obviously thinks it was related to someone using drugs, the other, that it was a quiet loner.
One thing we don't know about the Delphi case is what the original motive was. We don't know if he planned to take them the spot he did and kill them, or if there was an attempted abduction that went sour, or some other motive. JMO
Let us start again with not knowing. Maybe we should start anew,
not from the standpoint of the motive, but from the standpoint of opportunity. Who could do it? With two scenarios, a) he was chasing them. And b) it was random.
Make one thread, pull it all into it.
Like, he is out on Monday, he moves fast, he clearly knows the area, he has good spatial orientation, he probably walks fast or runs yet the gait is odd, he can walk on that bridge fast, no fear, he was done with it in a short time, he can change clothes and appearance fast, he can kill fast, too, he is mentally organized. He can make two girls get down the hill fast - fear? - a gun, probably?
He has time on his side, and he should not! It is as if he either knows who and how is going to pick them up (has access to their SM? Very likely), or he had the chance to check both sides of the bridge. He knows that no one is waiting them on either side now. He has to know this.
Whatever he left with his DNA, if anything, it was not much. Either he knows that there are no matches in Gedmatch, and won’t be, or he knows how not to leave workable DNA. Who would have this knowledge?
He is not in the CODIS...
And then there is the issue of early communication with the police that swayed them the wrong way. What is this about, and how could he persuade them? Too believable as a witness? Own good alibi? Was seen elsewhere?
Let us make a separate discussion, of opportunity. From what I have posted, it is obvious to me that he is not a local druggie. That he has a high IQ and is probably “a worrier”, they do perform better under stress. That he probably is a college grad or had good military training and has some minimal knowledge of the criminology. That he probably is very good at Googling.
I think we should pull it all together and then think what is most plausible, that someone helped, that he was alone, etc.
From my own post it seems to me that he has access to their SM. Because even if he knew them, saw them being dropped off, how did he know that dad would not pick them up in 15 minutes? And dads have guns these days.
