A witness who saw the Trayvon Martin-George Zimmerman shooting is claiming that the 17-year-old wasn't completely innocent.

It is strange that this is the first time that police say that the night of the shooting, there was a witness who saw it all.

The anonymous witness said that he noticed Martin attacking Zimmerman before Zimmerman shot him.

He said: "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."

Trayvon Martin was in a hoodie and Zimmerman was in red.

The witness said: "When I got upstairs and looked down, the guy who was on top beating up the other guy, was the one laying in the grass, and I believe he was dead at that point."

A local TV station talked to the anonymous witness.
