Surveillance video footage of George Zimmerman being led from a police car shortly after he fatally shot teenager Trayvon Martin does not appear to show any obvious signs of injuries or bloodstains, but his attorney says the video is too grainy to be revealing.
The footage, obtained by ABC News on Wednesday, shows a handcuffed Zimmerman getting out of the police car unaided and walking into the police station where he was taken after the shooting in Sanford, Fla.
It was taken about four hours after the deadly incident.
In the video, there are no readily visible signs of injuries to Zimmerman's head or blood on his clothes. However, he is wearing a red jacket, which could obscure blood stains. Also, at one point, an officer pauses to look at the back of Zimmerman's head, which he claims was injured by Martin.
Appearing on NBC's TODAY on Thursday, Zimmerman's attorney Craig Sonner described the video as "very grainy." He also pointed out that Zimmerman had been "cleaned-up" and received first aid in the four hours between the incident and Zimmerman's videotaped arrival at the police station.
Sonner has previously said that his client suffered a broken nose and a gash to his head during the altercation.
Neighborhood watch volunteer Zimmerman, 28, who was released without charge, claims he shot dead the 17-year-old Martin on Feb. 26 in self-defense after the teen attacked him.
Eugene O'Donnell, of John Jay College of Criminal Justice, said the video shows "that it's beyond dispute that there are no serious injuries, physical injuries, he's not in a hospital."
"There's no bruising that's observable," O'Donnell told MSNBC TV's The Last Word. However, he added that "it's possible that there are injuries that are not seen in the video."
Richard Kurtz, the funeral director who prepared Martin's body, was asked if there were any signs on his hands that he had punched someone.
"The only thing that I was able to see was the gunshot wound," Kurtz told The Last Word. "I could not see evidence like he had been punching somebody as the news media say he was punching ... It just did not add up to me."
