Trayvon Martin Eyewitness: George Zimmerman Had No Injuries

Appearing on Anderson Cooper's AC360 on CNN Thursday night, an eyewitness to the Trayvon Martin killing said that George Zimmerman appeared to walk away from the scuffle uninjured but, "very worried." The man who watched from his townhouse cast more doubt on Zimmerman's self-defense claim.

In the spotlight this week, Zimmerman's friends and family have been vouching for his character, and his father and defense attorney have talked continuously about Zimmerman's injuries during the incident.

Also this week, a police video drew attention showing a seemingly unharmed Zimmerman arriving at the police department after the killing. And now comes an eyewitness account to go along with those images.

Here's what the witness told Anderson Cooper:

"I don't know if it was an echo but it definitely made more than one pop ... After the larger man got off there was a boy, obviously now dead, on the ground facing down ...

"It was dark. I can't say I watched him get up, but in a couple of seconds or so he was walking toward where I was watching and I could see him a little bit clearer. It was a Hispanic man. He didn't appear hurt or anything else. He just kind of seemed very worried with his hand up to his forehead."
