SANFORD, Fla. —
WFTV has confirmed that autopsy results show 17-year-old Trayvon Martin had injuries to his knuckles when he died.
The information could support George Zimmerman's claim that Martin beat him up before Zimmerman shot and killed him.
The autopsy results come as Zimmerman's attorney, Mark O’Mara continues to go over other evidence in the case.
O’Mara wouldn't comment on the autopsy evidence, but WFTV legal analyst Bill Sheaffer said it's better for the defense than it is for the prosecution.
WFTV has learned that the medical examiner found two injuries on Martin’s body: The fatal gunshot wound and broken skin on his knuckles.
When you compare Trayvon’s non-fatal injury with Zimmerman's bloody head wounds, the autopsy evidence is better for the defense, Sheaffer said.
“It goes along with Zimmerman's story that he acted in self-defense, because he was getting beaten up by Trayvon Martin,” Sheaffer said.
The injury to Martin’s knuckle also fits with Zimmerman's story that before he shot and killed Martin, Martin had broken his nose and knocked him to the ground, slamming his head on the sidewalk.
But Sheaffer said there could be another explanation for Martin's knuckle injury.
“It could be consistent with Trayvon either trying to get away or defend himself,” Sheaffer said.
Zimmerman shot and killed the unarmed teenager almost three months ago after calling 911 to report the teenager was acting suspiciously.
Zimmerman said Martin threw the first punch and that he opened fire in self-defense after his screams for help went unanswered.
The FBI was not able to determine whether it was Zimmerman or Trayvon who could be heard crying out for help in 911 calls.
The defense is trying to decide what evidence it wants a judge to keep confidential before the media gets a chance to see it, but WFTV is being told that could happen in the next week or so.
In the meantime, there’s new information surfacing about Zimmerman.
ABC News said it has obtained Zimmerman's medical report from the day after the killing. According to ABC, the report shows Zimmerman had a broken nose and abrasions on the back of his head.
