Websight: Fantastic Work!!! I'm new here. Your work changed my perspective of this guy completely. My (Our) imaginations get carried away because we know the outcome of this horrible crime. But it clearly did not start out that way. Thank you so much for providing additional perspective.
I have also posted a pic of the jacket I believe he wore. It's a Rothco three season concealed weapon jacket with a pistol pouch. It can be purchased for $72 at Walmart, as well as a variety of other places. It comes in blue. It is likely that he is left handed since the right pouch appears to have a gun in it. A lot of people carry concealed weapons and buy this jacket. it's a little bulky because it has a gun and mags of bullets in the inside. I don't think he has "murder tools" tucked in his jacket.
With your work, and this very different perspective of a jacket, I theorize that this guy was there for different reasons than murdering two kids. He was walking purposefully and determined because he had something to do. What was it? I think it possible that the girls just showed up in his path.
Also below is a youtube link to a guy speaking and demonstrating this jacket. Very interesting.
Plausable?
