Marc McConnell's story isn't internally consistent. He claims he was 200 yards away, yet he claims he could hear two guys in the car having a heated argument (while himself being arrested by the police). I doubt it.
Virginia's story is much more plausible, she was, at least by all accounts in the car that LeVon was driving when he was killed. She was not somewhere between hundreds of yards and a mile away.
Marc McConnell sounds like a LE plant. He shows up on the scene 3 weeks ago. He's driving with Ammon Bundy in his Jeep. Ammon Bundy is arrested and Marc McConnell is not arrested. Does this sound fishy at all?
Victoria Sharp's account makes more sense as she was an actual eye witness.
