I think if LE had any early proof HE was killed a PTL, they would've let the family know in so many words. They wouldn't have let them suffer all this time wondering.
Prior to the search warrant, LE publicly stated their belief that HE drove to PTL. There must've been evidence they didn't release to the public.
The seat,mirror etc. placement in HE's car would've been circumstantial - proof of nothing, so it must have been something more than that.
I'm thinking the expert video analysis was some extremely grainy thing from a traffic light or something that placed Moorer vehicle in the area at the right time.
It wasn't until after the search warrant that they added the kidnapping charge, then murder.
DNA evidence wouldn't have been processed that quickly for the kidnapping charge, right? That was only one day after warrant was issued.
Just have a sick feeling it's photographic evidence.
