A Sanford, Florida, police surveillance video (below) obtained by ABC News shows no blood on George Zimmerman, who allegedly shot and killed Florida teenager Trayvon Martin.
Zimmerman told police last month that Martin punched him in the nose, knocking him down, and began banging his head into the ground. That is when Zimmerman allegedly shot Martin.
The initial police report noted that Zimmerman was covered in grass, and was bleeding from the back of the head and nose. Zimmerman’s lawyer has also said that his nose was broken.
However, the video, from the night of the shooting, shows no blood on Zimmerman's head or clothes, casting doubt on the notion that he acted in self-defense.
Chris Serino, the Sanford investigator, filed an affidavit on the night of crime saying he was unconvinced of Zimmerman’s account. However, the state attorney’s office told Serino not to press charges against Zimmerman because there wasn’t enough evidence against him.
