Backpack & Rifle Impossibility
Even if Tyler Robinson were on campus September 10, citizen investigators argue he could not physically have carried, concealed, and fired a scoped Mauser .30-06 through the clothing and pack states visible on camera. ProjectConstitu summarizes: "tight jeans and a backpack that couldn't hide a rifle." These are physics and surveillance arguments, not court findings.
Scoped rifle size vs clothing
A Mauser Model 98 with scope is a long, rigid package. CK_FILE and Stairs Guy analysis stress:
- Morning Tyler wore light-colored shorts — cannot realistically hide a broken-down rifle in shorts or pant leg (when not wearing long pants)
- Stairs Guy wears dark jeans — different wardrobe than midday Tyler approaching tunnel without backpack
- Disassembled rifle still too large for plausible concealment in a half-empty student pack
Backpack volume logic
| Observation | Implication argued |
|---|---|
| Tyler's light blue pack ~50% full after leaving car | Little room for rifle + scope |
| Stairs/roof figure pack ~90–95% full | Different person or different loadout |
| Outfit change mid-campus | Should reduce pack contents if rifle stowed — yet roof suspect pack looks fuller |
Conclusion in CK notes: a typical 22-year-old would not swap backpacks and hats during a flee — supporting Stairs Guy Identity Gap.
Gun path IN and OUT fails
If Tyler never carried the rifle onto roof in that clothing, the official story requiring gun into campus → roof → woods collapses unless:
- Another person supplied the weapon on roof or in tunnel, or
- Rifle was pre-positioned days earlier (not the public FBI timeline), or
- Stairs Guy is a different individual entirely
None of these is proven here; each is an investigative branch when backpack/rifle math fails.
No GSR test
UVU Tent and ProjectConstitu threads note Tyler was reportedly never given a standard GSR (gunshot residue) test — unusual for a shooting suspect if physical proof were priority. See No GSR & Physical Tests.
