Exploding Røde microphone / shaped charge
Rumor Contested Alternate mechanism
Owens (eps 350–351) and John Bray: the wireless pack on Kirk's shirt was rigged and exploded. Against: Hull's hearing summary of a gunshot-to-neck autopsy, a jacket fragment, and close witnesses describing a neck wound with massive bleeding.
A slow-motion still and SUV floorboard shards are not a residue lab. Owens compared those shards to a YouTube teardown of a Røde Wireless Pro. No court filing in this archive backs an explosive. Native autopsy, native mic remains, and a residue test would be the tests. Until those exist here, this stays a rumor with medical testimony sitting against it.
