THIS is what was initially reported concerning the Good Samaritans:
Griffin also said two Good Samaritans found Murdaugh injured at the scene and took him in their car. Murdaugh called 911 from the car. The two people delivered Murdaugh to an ambulance further down the road, he said. From the ambulance, he was then airlifted to Savannah.

So the Good Samaritans arrived on the scene at just the right moment. AM must have reached inside his car for his phone because blood was found there and LE has sent it in for testing, according to news reports.
From the safety of the rescue car, AM called 911. The two people then delivered the victim further down the road to an ambulance, and from there he was airlifted in the chopper.
*The bottom line is solicitors know better than to leave the scene of a crime. AM could have safely waited for the ambulance in the Good Samaritans' car.
*Superficial wounds don't require choppers.
*There is no explanation that can justify AM's own knife causing the tire damage in this incident.
