Back in April 2019, when the YBG sketch came out and we found out it had been drawn only a few days after the murder, one of my initial questions was if maybe the reason LE didn't go with the younger sketch first was because the source of that sketch was unreliable for some reason, like a child, a known drug addict, something like that.
Looking at it now, I feel like BB's descriptions of both the vehicle and the man on the bridge are the outliers. A smaller SUV-type dark vehicle was seen in the CPS lot at 2:10 and again at 2:28. A similar vehicle was seen driving west past HH at 1:27, which LE says was likely RA's Ford Focus. All of those descriptions can be argued to be the same car, IMO. But then suddenly you have a not black '65 Comet right in the middle of those other descriptions, at 2:14. BB's description of the vehicle doesn't match the others.
Then you have three juveniles with only slightly varying descriptions of the man they saw. The one who claimed to see his face described more of a middle-aged man with gray hair. The other described the same clothing as the man in the bridge video. BB, meanwhile, described a young slender man with poofy brown hair. Doesn't match.
It seems to me that BB was, perhaps, not as reliable with her descriptions when in comparison to the other witnesses. I can see LE leaving her non-matching statements out of the PCA, because they really only used her to support the timeline AND put a man on scene only minutes before L and A arrived at the bridge.
That still doesn't explain why LE decided to change to her sketch in 2019. But since RA's arrest, the sketches have been vaguely hinted at being one in the same man by DC. JMO. I have trouble with that.
And why, for so long, through both sketches, did LE have reddish-brown hair in the suspect description? That doesn't match what any of the witnesses said, ASAIK. I always thought there might have been hair left at the CS, but it doesn't make sense. JMO.
