Witness: Martin attacked Zimmerman
ORLANDO - A witness we haven't heard from before paints a much different picture than we've seen so far of what happened the night 17-year-old Trayvon Martin was shot and killed.
The night of that shooting, police say there was a witness who saw it all.
...
"The guy on the bottom who had a red sweater on was yelling to me: 'help, help
and I told him to stop and I was calling 911," he said.
Trayvon Martin was in a hoodie; Zimmerman was in red.
The witness only wanted to be identified as "John," and didn't not want to be shown on camera.
His statements to police were instrumental, because police backed up Zimmerman's claims, saying those screams on the 911 call are those of Zimmerman.
...
Sanford police say Zimmerman was bloody in his face and head, and the back of his shirt was wet and had grass stains, indicating a struggle took place before the shooting.
