I’m pretty sure the girls’ movements were accounted for by LGs phone via both the GPS info & step counter. That’s part of the information used to verify the timeline. It’s possible they stopped walking now & then to text, take & post pictures. It’s possible they had a creepy interaction with RA which he chose to avoid discussing.
I can’t give you a definitive reason why RA changed his timeline for that day. My only guess is he wanted it to appear as if he wasn’t involved in the murders & figured the earlier he said he left, the better even though he couldn’t have any ideas of the time unless he’d been checking his watch that day or had time stamped photos from a camera he may have had - utter speculation.
The conflicting statements he gave concerning what times he was there weren’t really major points of contention made in the PCA or the trial (that I can find or was reported). It was obvious he didn’t leave at the earlier time because his vehicle was seen on the HH camera footage of him driving towards the CPS building around 1:30. LE stuck to his original time from 2017 in the PCA & at trial & backed that up both times with the following:
- the video from HH of him going towards CPS building @ ~1:30
- eyewitness statements & times on the trails after 1:30
- the fact no one else reported seeing BG/RA on the trails or on 300N after 2:13 but before 3:30
- his car was still reported being seen at the CPS building after 2:13 by eyewitnesses
- the BG video timestamp from LGs phone
- SC seeing him at 3:30 on 300N
Yes, had his phone been available, the info might have been helpful but given what we know from above, it’s just more of the same evidence, really. LE didn’t focus on potential lies via his phone because the above is evidence he was lying.

ETA clarity on 2:13 to 3:30 timeframe
