SANFORD, Florida (Reuters) - Neighbors of George Zimmerman say he had bandages on his nose and head the day after he shot dead Trayvon Martin, supporting statements by the neighborhood watch volunteer that he was beaten in a confrontation with the black Florida teenager.

The extent of Zimmerman's injuries could be crucial to his legal defense under Florida's "Stand Your Ground" self-defense law, which allows the use of deadly force when someone has the reasonable belief he could face death or great bodily harm.

Police said Zimmerman, who has been charged with second-degree murder in the racially charged case, was bleeding from the nose and the back of his head and was treated by medics before being taken to Sanford police station after the February 26 shooting.

But public doubts were later raised by the release of a grainy surveillance video from the police station in which no injuries were readily visible.

Zimmerman later sought medical treatment for injuries including a broken nose, his former lawyers have said.

Jorge Rodriguez, Zimmerman's next-door neighbor, told Reuters that when he saw Zimmerman the day after the incident, "he had two big, butterfly bandages on the back of his head, and another big bandage...on the bridge of his nose." He was talking to a police detective in his driveway.

Rodriguez's wife Audria also said she saw the bandages and a third neighbor, who spoke only on condition of anonymity, agreed with the Rodriguez couple's account. "I saw two bandages on the back of his head, and his nose was all swollen up," said the witness, who had watched from a nearby second-floor window.
