Re Batbrat's post (welcome!):
New to Websleuths. My first post.
My area of interest and study is mainly anatomy and kinesiology. I have made my own evaluation of the surveillance footage, compiling physical trait similarities of Bevers family members to the suspect.
Head-forward posture:
Hypermobility (hyper-extended joints or lax ligaments):
Sway back:
Additional observances are pronate ankles:
Height approximation 70-72" (based on standard commercial door handle installations of 950-1000mm):
The suspect in the surveillance photo walks with a toe-out gait and what appears to be pronate ankles. These traits are often linked together, as well as to other hypermobility issues such as lax ligaments and joint weakness. I was unable to find enough footage to make a strong link between the suspect and either Bevers man with regards to these characteristics, but both Bevers men do appear to walk with toe-out gait. People with hypermobility are prone to knee and ankle weakness and injuries. The suspect can be seen in a few frames walking awkwardly, as if wearing oversized footwear or compensating for weakness or limping.
I feel these physical similarities are notable enough to point out.
Great to see the detailed offering in this post. I completely agree with the pronated feet analysis, as a member of my family also walks with right foot turnout (due to flat feet) though not nearly as severe as the subject in the video. Several threads back, in fact, I posted that same foot diagram. In my opinion, perp probably thought he was disguised head to toe with the SWAT get up, so was not concerned with what the cameras might see. Gait is not something (IMHO) that a suspect could disguise easily for 30 minutes of video when distracted with the bigger task of murdering someone and vandalizing and/or trying to make this look like an interrupted burglary. Fact is, a person with turnout does not
always display the exact same degree of turnout while walking for 30 minutes (depending on terrain, whether turning a corner, etc.), but a certain degree is generally consistently present. When LE first put out the video they said to look for someone walking with this unusual gait (not standing position, but walking). I believe they said that because their experts agreed with you that this is likely true gait for this person, not something faked for camera. (Remember, they have viewed the entire 30 minute sequence with much better video resolution.)
As regards to the part of your post picturing RB and BB...while yes, it appears they do have a degree of hunchback, that characteristic is almost universal with older people, particularly men, starting about middle age. So the photos alone won't convince me they could be the men in the SWAT uniform. BB is above-average in height, head and shoulders above everyone else when photographed. Above average in height, certainly over 6' in these photos. So I don't think even LE think that BB could've been the actual man in the SWAT suit, because they have said the suspect is 5'8" to 5'9" tops. That doesn't mean they've cleared BB of involvement in perhaps other ways, but IMO it does mean he's ruled out as SWAT guy.
Regarding RB...besides the fact that he has a middle-aged paunch which I personally don't see in the video views (nor do I see the pronounced foot turnout in RB), his cellphone and travel records most likely will rule him out or not (and my guess is they have), but ruling out suspects publicly is not in the best interests of this investigation right now. Because at this point LE probably could rule him out (as SWAT guy) if they wanted to. But it'd be my guess that LE wants perp to relax, and think a vast pool of people are being investigated, that LE really has no clue. (Remember, they spoke to perp almost as a kid in that press conference, appealing for him to 'talk to someone'.)
I still maintain SWAT guy is teens to twenties, local, fit, and not a 'professional' hired hit, though this killing could have that aspect to it. (I believe SWAT guy did not leave scene in a car but walked/jogged to his next destination.) I believe SWAT guy knew Missy, but that there may be more than one reason why SWAT guy agreed to carry out this targeted albeit unprofessional hit (his youth, the fitness aspects, and, my personal theory, steroid use and sales being interwoven, here.) And the complexity of motive(s) and the unknown number of peripheral people involved are what is causing this case to 1) have so many specialty agencies involved, and 2) proceed slowly, methodically, and thoroughly.
