(CNN) – An autopsy conducted for the family of Michael Brown found no evidence that he struggled with the officer that shot him before his death, according to pathologist Shawn Parcells, who assisted in the examination.
But he added that the team did not have access to a key element to reconstructing the shooting scene.
"When you are looking at an autopsy, you have the autopsy of the body and literally the autopsy of the crime scene. And the autopsy of the crime scene really hasn't been done yet," Parcells said in an interview with CNN's "The Lead with Jake Tapper."
The police officer who killed Brown says the teenager rushed at him full speed in the moments before the shooting, according to an account phoned in to a radio show Monday, and confirmed by a source with detailed knowledge of the investigation.
"All we know at this point is that the gunshots that occurred to the front part of the body came at a front direction. Does that mean that he was rushing the officer? Or does that mean that he was simply standing there and giving up? We can't prove that off of what we saw," said Parcells.
