Yes LM and CR, 18:15 to 19:15 would be a crucial time, but also 19:30 to 20:15 or 20:30, as DJ said that when TH came back an hour later, they drove round for about 15 minutes. So according to this statement we would have the following:
17:15 - 18:15 Playing guitars at DJ
18:15 - 19:15 ???
19:15 - 19:30 Mayfair apartments, south of bayou.
19:30 - 20:30 ???
20:30 - 20:30 Meeks, Moore, Byers
20:30 - 21:15 ???
DJ says in this statement, TH and DJ took Amanda with them when driving around for 15 minutes, then DJ was dropped off (not Amanda).
21:15 - 21:?? Catfish restaurant.
After driving from Catfish to the woods, looking for a while, TH and PH go home to change. This is where TH disappears again. (I think it was for about 30 - 45 minutes, PH stated this somewhere else). This is where the PH statement, and DJ's are not synchronous. PH says she walked to DJ's, then DJ drove her back home and TH was there. DJ says in this statement, PH came in her car, was not fit to drive, so he drove her round a while. TH then came to DJ's in his truck.
As CR mentions, would PH have told the police if she had been driving without a license ? I don't think so. I found this interesting, because if this DJ statement was true, it would mean that TH was out in his truck in this third unaccounted time frame of 30 to 45 minutes. This is a good example of how things look in reality. On paper it all seems easy. Everything is dynamic, at the time the three boys were being murdered, other things were going on, like people driving around without a driving license, and lot's of other things the police need not know. It's the details that matter, the details like who is driving which car at which time, what happened to the green beans, did SB have his pocket knife with him or not ? These are the things that a good detective would have to sort out. We know TH came to the Catfish with a car (was it the White Oldsmobile, or the Blue Le Baron ?). When TH took DJ to Mayfair, bayou, was it with a car (which ?) or the truck ?
Details, details, details.
