do you mean this witness??
"Witness 6
This witness lived a few feet from where Trayvon and Zimmerman had their fight. On the night of the shooting, he told Serino he saw a black man on top of a lighter-skinned man "just throwing down blows on the guy, MMA-style," a reference to mixed martial arts.
He also said the one calling for help was "the one being beat up," a reference to Zimmerman.
But three weeks later, when he was interviewed by an FDLE agent, the man said he was no longer sure which one called for help.
"I truly can't tell who, after thinking about it, was yelling for help just because it was so dark out on that sidewalk," he said.
He also said he was no longer sure Trayvon was throwing punches. The teenager may have simply been keeping Zimmerman pinned to the ground, he said.
He did not equivocate, though, about who was on top.
"The black guy was on top," he said."

there have been a lot of changes in all these witnesses stories as time goes on, plus it was dark and he was looking out a window - all doors were shut
the problem w/ shooting TM on top of GZ, even if TM falls forward, GZ would still have to roll the body off him to get up, imo i do not see an explanation of how any one can be shot like this and end up face down
