1. ANSWER — No, there is no credible evidence from official sources that Tyler Robinson disassembled and reassembled the Mauser Model 98 rifle after allegedly shooting Charlie Kirk. Official documents (probable cause affidavit, charging documents) state he hid the fully assembled rifle (with scope) wrapped in a towel in woods near Utah Valley University; a screwdriver with his DNA was left on the roof, but no mention of disassembly. Conspiracy theories on social media/Reddit/Quora speculate he disassembled it to carry in backpack/pants (citing his "limp" on video), reassembled it to hide, but this is unsubstantiated speculation, contradicted by rifle's size (~43-48 inches assembled) and lack of limp while running/jumping off roof.12

2. EVIDENCE —
- Official sources: Probable cause affidavit (Sep 12, 2025, Utah AG's office/Fox News) describes rifle found "wrapped in a dark colored towel... Mauser Model 98... with a scope mounted," no disassembly noted; obstruction charge for "moving and hiding the rifle."1 Charging docs (Sep 16, 2025, Utah County Attorney Jeff Gray) confirm DNA on trigger/towel/casings/screwdriver (roof); video shows "unusual gait... consistent with rifle hidden in pants" pre-shot, but running normally post-shot.34 Wikipedia/FBI (Sep 15, 2025) notes screwdriver DNA match, rifle in woods.2
- No official reassembly claim: Searches of court docs/AP/BBC/NYT/USA Today yield zero mentions of "disassemble/reassemble." FBI Deputy Dan Bongino (Sep 15, 2025) speculated drop fully assembled.5
- Conspiracy claims: Facebook/Reddit/Quora/Instagram (e.g., Apr 2026 posts) question logistics (time/tools to disassemble Mauser, fit in backpack, reassembly without screwdriver), but no proof; fueled by inconclusive ATF bullet match (Mar 2026 filing, Daily Mail/PBS, defense motion—not exoneration).67

3. CREDIBILITY — 9/10. Official court/prosecutor docs consistent; claim stems from unverified online theories, absent from affidavits/FBI. Bullet mismatch inconclusive (fragment damage common), not disproving rifle.8

4. BIAS — CENTER (court docs: Utah County Attorney, Sep 2025; Fox News/BBC/USA Today/AP reports). Conspiracy sources: FAR LEFT/RIGHT fringes (Reddit/Facebook questioning "frame job").12
