Y’all have done some good work here! Sorry late to the party. And my questions are most directed to the FBI and Aurora, Colorado Police Department.
On the TMSI logo on the shirt…. a button up. Wish there were additional pictures of it. Can’t tell whether it would be long or short sleeve? As many note likely a trucking or freight logistics company.
The necklace….. any attempts to enlarge that image hampers (with my elder eyes) any useful information in it. And some of the pendants or trinkets on it might be quite helpful!
As to the truck, what year truck were the items pulled from? What make and type? Cab with ‘sleeper’ etc? This would be helpful to better align with the other items, i.e. the TMSI patch. And to consider long haul routes and type of materials moved, locations, destinations. And to date that with other items displayed.
I concur that the jacket logos appear to be a magic wand in hand with sparkles (maybe snow). Assuming as noted above probably from an amusement park, due to the stylized lettering. Initial thought was a trucking company of that name would use a less stylized lettering? (Yet it does span dates 1970s to mid 1990s IIUC.) Tried to search for old post cards of Magic Mountain Express. Found a few for sale, but they do not use a capitol letter MAGIC MOUNTAIN with Express. Are there any markings or other features on the jackets? Any makers marks that would better help narrow this down and date the items?
On the Never Never Beg for Mercy t-shirt, same questions as for the jacket. If a band as good suggestions above, is that a tour or song done by them? Any other markings on the shirt?
Sure wish the investigators would provide better pictures. And if they have the items in evidence, to take new better photographs - and publish them! As others noted, I could not find that Vicap Alert bulletin. And wonder if any DNA or other forensic evidence might exist on the items recovered? Are there any prospects for that happening? MOO
