(CBS) SANFORD, Fla. - Enhanced surveillance images of George Zimmerman, the neighborhood watch captain who admitted shooting 17-year-old Trayvon Martin, appear to show a bump, mark or injury on the back of his head.
CNN reports this new piece of video evidence would appear to lend credence to opposing versions of what happened the night Trayvon Martin died.
Sanford police released a new, higher-resolution surveillance video of Zimmerman entering the police station the night of Martin's death on February 26. The sharper footage shows a possible gash or injury on Zimmerman's head more clearly than a previously released video, which had a grainy quality.
The Los Angeles Times reports Zimmerman was seen by paramedics after the shooting, a police report indicates. An initial police report noted that he was bleeding from the nose and the back of the head.
28-year-old Zimmerman has said he killed Martin in self-defense, saying the teen punched him and slammed his head into a sidewalk before the shooting, according to family members and police.
Jasmine Rand, a Martin family attorney, said Tuesday that it doesn't matter what the videotape shows.
"That does not change our position," she said. "Once again, George Zimmerman was the aggressor. He pursued Trayvon in this instance. If he did have any medical injuries, that did not give him the right to use deadly force and shoot and kill Trayvon."
