At this time I believe McConnell is/was an FBI informant. he was released after questioning.
“Mark McConnell, who was with the Bundys at the time of their arrest and later released, disputed this account in a video on Facebook. He said that Finicum “charged at law enforcement” and ended up getting shot â and that the stuff about Finicum being shot while his hands were up was “nonsense.””

Thing is McConnell wasn’t even near the shooting scene with Finicum.
He had stopped at the first roadblock. Unless he had Superman-like vision and hearing, he couldn't have seen and heard what happened a mile up the road.
Questioned and released. Just like that.
