I'm not sure what someone would walk like, when techniquely fleeing the scene where they'd just murdered two people, but being aware most of these luxury homes have video cameras.
IMO a walk can't be faked for any distance, the person gets distracted by their thoughts and forgets.
IMO the person is more concerned with their face not appearing, by looking toward the street. A normal person would at least glance at the mansion as they pass it.
on the flip side;
I know from private investigation case studies that people can manipulate their gait very easily. Some put a pebble or pin in their shoe so it makes them limp, have one shoe smaller than the other, put shoes on the wrong feet, or place some object under the foot and that makes you use the side of the foot as you walk. Another was a person put a broken broomstick along the side of the body to make them walk more stiffly on one side, it appeared they were dragging their one leg as it would not bend at the hip area. Others put multiple layers of clothing on that made the arms and body swing in ways that were not their normal gait.
If this was the perps planned route, they already knew who had cameras, so this was intentional to walk past them, in a nonchalant manner - why.
I also think the head/body movement can be other things,
- it was -16 with wind chilling winds way colder so keep head and face out of the wind
- they could be in shock, maybe murder was not the initial plan
- simply be pleased with themselves and going over everything that happened that night in their head (own world oblivious to the surroundings)
- head down to see if ice patches on the sidewalks
- is local to the area and walks it all the time so no need to look at houses as you pass
- if a hitman maybe took the wrong road out and is lost, cannot find the getaway car, thus why on many cameras in a certain radius of the Sherman home.
- the gait being off, maybe his foot was cold or wet with snow inside the boot and he was moving it differently
- arthritis in the hip or knee, in the cold could make you walk that way
To me I am impressed of the work that TPS have done in this investigation, this is an example of the depths of work and data they have been sifting through. Video evidence had to be collected within the first day or 2 before video was taped over and lost but many of the homes in the area. The LE most likely had many neighborhood recordings that had to be salvaged or forensically they were able to locate data that had been recorded over but with technology and expertise they can get the older copy, this would take a lot of time. Not only to collect from anyone with a camera within a ??KM radius within the first couple of days?
Some of the reports from neighbors that LE was not interested in the camera recordings are surprising to me. A murder happened across the street from our home (gang related hit - he was in hiding and they found him in a quiet new rural neighborhood shot him in a home and fled) The next day we had a note on our door to please provide our camera details to LE, gave us instructions to call then asap and on how to do give them a copy for a specific time range they need. in this case they asked for video 3 hours before the murders. That same night they took the copy of video (less than 48 hrs after murder) they called to ask about the time clock on our video - so they were reviewing it - and our camera angle had little to nothing to assist them, the other neighbor video came with sound caught a lot more than ours, they did not need ours to back up anything but yet they had to view it.
Understanding that M/S was initial thoughts and area recordings were not thought to be required. I am still not sure if that was an intentional LE ruse, I cannot recall an answer as to why they checked the street drain directly outside the Sherman home. What were they looking for? A murder weapon? if it was M/S and found as they were?
