Hopefully helpful, but below is a summarized version as best as I can discern from the RA PCA to compare consistency and detail. I'll call the juvenile females J1, J2, J3 or J? when it's unclear who is speaking during the interview(s). To be consistent with Gray H's video, will call the adult Sue who turned around at the bridge, and the final witness I'll call MB1 (for muddy-bloody). It is not stated in the PCA whether the juveniles heard each other's version or provided independent accounts though consistent references to "they" suggest all 3 were interviewed together which could be another clue (see below) that one or two of the juveniles were very young. On the flipside the paragraph begins with "Interviews" were conducted with 3 juveniles, which could suggest separate talks with each of the 3, or it could suggest the group of 3 were contacted a plurality of occasions.
Location/Position
J1, J2, & J3 all seemed to be lumped together as "they" in advising a) they all were on the MHB trail 2/3/17, b) they all were heading toward the Freedom Bridge (which commonly implies away from the High Bridge portion) to go home (which would seem to indicate they were related to each other, all lived at the same place, or in the event one (which could be the taller one RA describes) was a babysitter for the 2 younger ones, all 3 were headed back to somebody's home. They don't say headed to the car or to the parking lot - it is reported as home which may suggest they lived very nearby. c) they all agree they encountered a male who had passed the Freedom Bridge and was on the way toward the High Bridge.
RA '17 narrative - was on the trail (not dated which IMO suggests this narrative was given the same day the described events occurred [which would've been 2/13], and that since a time was noted), walked to the Freedom Bridge then onward to the High Bridge. Though clear that he says he saw three females while there at the Freedom Bridge. the second statement is a bit unclear as he states... "He walked from the Freedom Bridge to the High Bridge. He did not see anybody, although he stated he was watching a stock ticker on his phone as he walked." MOO I believe him saying he did not see anybody is directed toward the journey between bridges and not necessarily on the High Bridge itself, as I just feel like walking the rickety High Bridge requires an attentive focus and he would not have been distracted and on a phone while specifically on the bridge.
RA '22 narrative - was on the trails on 2/13/17, saw juvenile girls (no number of girls noted), on trails east of the Freedom Bridge, then onward to the High Bridge as far as the first platform (there were six platforms evenly staggered), then walked back, sat on a bench, then left. (there is no time approximation provided as to how long each of these separate things lasted)
Summary - largely consistent, only discrepancy from RA '17 to RA '22 moves the meeting east of the Freedom Bridge instead of while at the Freedom Bridge, but the '22 version is a match to J1/J2/J3's description somewhat away from the actual bridge.
Descriptions of the Other parties
J1 - male was kind of creepy, wearing blue jeans and a really light blue jacket which was a duck canvas type, hair was gray maybe a little brown, did not really show his face
J2 - advised she said Hi to the male but he just glared at them, dressed in all black with something covering his mouth (MOO the eyes to glare were visible, but she would not have been able to see if male greeted back or murmered anything if mouth was not visible), said not very tall but then - no taller than 5'10 (which isn't short), and with bigger build, had hands in pockets and was wearing black jeans, a black jacket, and a black hoodie
J3 - man wearing a blue or black windbreaker jacket with a collar (MOO this would be like nylon material and inconsistent with canvas material but others may disagree), hood was up from clothing underneath jacket, baggy jeans, and taller than her (MOO by around 14 inches IF...) as her head came up to his shoulder. (MOO I might place this witness as a 4'4 third-grader other than she later said...) he was walking with a purpose like he knew where he was going. (MOO which doesn't sound like an observation of a 9-year old), she agrees with J1 that male's head was kept down, and she agrees with J2 that male's hands were in pockets. She agrees (assumedly with J2) that someone said Hi to the man and claims nothing was said back (though does not mention a face covering that might've muffled a greeting or couldn't read lips.), did not get a good look at his face.
RA in '17 - says little about this encounter, except that he did not speak to them nor remember any description other than it was noted that one was taller (assumedly than both of the others), and that the taller one (possibly older? JMO if it was that noticeable) had brown or black hair (which MOO only eliminates a small % of the local population) He does mention he observed more than one vehicle parked at the High Bridge trailhead (which would've presumedly lead to others being in the vicinity) but could not describe any of the vehicles, nor were any photos or videos of anything taken. MOO he was wanting to place himself on the scene as a cover but was cautious not to say much that could get him in trouble later.. most notably in '17 does not appear, per what's recorded, to describe in any way the clothing we was wearing that day. Perhaps the CO didn't ask but it would've seemed pertinent for CO to ask and/or RA to offer his wardrobe such that if others came forward with descriptions of people on the trails they'd know how to identify and perhaps ignore this proactive "kind citizen".
RA in '22 - recalls a bit more detail and this time does describe his clothing - as a blue or black Carhartt jacket with a hood (MOO did he own one of each color at that time?), blue jeans, and maybe some type of head covering. Except for any description of footwear, nor any mention of something around his waist, he comes very close to describing the man in the pics and video previously made public and displayed all over town. This time he seems more clear that he saw no one anywhere that day except for the 3 girls at Freedom Bridge.
Summary - largely NOT consistent... knowing the ages of these witnesses and knowing how long after the encounter this interview(s) took place (the PCA interestingly doesn't date it as it somewhat does the RA interviews) would help immensely as to the degree of reliability to expect. But given the 2 most prominent pieces of clothing on BG per L's video were his NAVY BLUE jacket and LIGHT BLUE jeans, none of these 3 juveniles hits a full match - J1 reports a "really light" blue jacket, J2 reports black jeans amongst all black clothing, while J3 gets closest but unless we knew her height back then, she seems to describe him as someone substantially taller than her, which RA is very rarely described as far taller than anyone. The 3rd most prominent item BG was wearing in L's video was the thing around his waist, which 0 of the 3 girls recalled noticing. To top it off, it appears from one statement that J? states in same interview that man they encountered "matched the description of the photograph taken from L's video" which means when providing their descriptions it seems they already a confirmation bias picture in their mind suggesting what they should've seen and still didn't come up with a match. JMO - I DON'T SEE HOW THESE GIRLS WOULD BE HELPFUL WITNESSES TO THE PROSECUTION in terms of establishing this man was without a doubt BG... or that BG is RA.
Sue - describes seeing 4 juveniles (not 3, but common belief is that it's the same J ones above) crossing the Old SR bridge above her as she drove underneath approaching her parking spot to hike. Walking toward the high bridge, she states seeing a man near the High Bridge but again it's stated as "matching the one from L's video" so she kind of already knew what she was supposed to be seeing, saw him wearing blue jeans and a blue jean jacket (which is not the same in material nor color as a canvas, windbreaker, or navy jacket). Advised she turned around at the bridge (implying she never set foot on the bridge). Advised the male was on the first platform (consistent with RA's stated position) though she approximated that distance as 50 feet from her (which MOO but perhaps someone else can verify, the first platform is considerably farther away than the start of the bridge than 50 feet. 50 feet would've been very close and she should've gotten a great look at his face & clothing from that distance IMO. JMO -
NOT SURE THIS WITNESS LIKEWISE IS MUCH HELP TO REALLY EITHER PROSECUTION OR DEFENSE, IN ESTABLISHING, OR NOT, THAT THE MAN DESCRIBED IS BG... or that BG is RA.
MB1 - states she was traveling eastbound (MOO assumes that to be driving) and crossed paths with a male walking westbound, described him wearing a blue jacket and blue jeans, and was muddy and bloody. Suggested the idea of him being in a fight but didn't necessarily disclose how that conclusion was reached. No other detail mentioned if all mud and blood was on dark clothing or might also have been on light pants or skin?? Apparently this witness wasn't concerned enough to stop and offer assistance nor report to 911.
JMO - IT WOULDN'T HARM THE PROSECUTION TO BRING THIS WITNESS FORWARD TO HELP ESTABLISH THIS MAN AS BG AND/OR A MURDERER, BUT THIS WOULD NEED TO BE PAIRED WITH STRONGER EVIDENCE ELSEWHERE TO WITHOUT A DOUBT CONVINCE THAT THIS MAN WAS RA.
Last PS - it was only in the '17 interview that RA provides a time that he was present at the bridge, saying 1330 to 1530, or 1:30 through 3:30. JMO as he describes in '22 his activities at the bridge that day from walking approx 1.1 miles from side road building to start of bridge (say 25 minutes), walked (MOO) 150 feet onto bridge to platform (1 minute), perhaps "watched fish" 10 minutes tops IMO (there's no rail to lean on, he didn't bring a lawn chair to sit down, etc), walked back the 150 feet, (1 minute), sat on bench - MOO give him 15 minutes tops for this, then the 25-minute repeat of hike back to car/side road bldg, this only cumulates to 77 minutes. Assuming the 1:30 arrival is solid based on '17 interview and confirmed with Harvestore video, that would present him leaving much earlier, like 3:00 max but possibly pre-2:50, than MB1's nearly 4:00 sighting. If there's any alibi, video, or other unreleased evidence LE has that suggests RA had driven out of the trail area by around 2:50, that would give LE a tough reconciliation with L's video that sets a solid time of abduction at 2:13.
OVERALL THAT ANY or ALL of THESE WITNESSES IMPACT A TRIAL - MOO - "Preponderance" = Maybe, "Without a Doubt" = no way, too weak, too inconsistent, too many places that Defense can insert uncertainties. As others have said DNA, finger/foot prints, finding items only the killer would have, etc are probably needed to get to the required guilty level. His own admissions are the much better evidence of placing him somewhat near the CS than any of these witness sightings, but even he yet hasn't gone as far as saying he was ever near the South End abduction site, ever near the downhill CS, or obviously admitted he is BG.
Thanks for enduring this long post
