Autopsy Reveals Trayvon Martin Was Killed By A Single Gunshot Wound

Florida teenager Trayvon Martin died from a single gunshot wound to the chest fired from “intermediate range,” according to an autopsy report reviewed Wednesday by NBC News.

17-year-old Trayvon Martin was shot and killed in February by George Zimmerman, who claims to have done it in self defense. A new report says an autopsy found that the skin on Martin's knuckles was broken.

Florida teenager Trayvon Martin died from a single gunshot wound to the chest fired from “intermediate range,” according to an autopsy report reviewed Wednesday by NBC News.

The official report, prepared by the medical examiner in Volusia County, Fla., also found that the 17-year-old Martin had one other fresh injury – a small abrasion, no more than a quarter-inch  in size –  on his left ring finger below the knuckle.

Separately, a medical report on Martin’s alleged killer, 28-year-old George Zimmerman, prepared by his personal physician the day after Martin’s shooting in Sanford, Fla., on Feb. 26, found that the Neighborhood Watch volunteer suffered a likely broken nose, swelling, two black eyes and cuts to the scalp. That report, first reported Tuesday by ABC News, also was reviewed by NBC News.

Both documents are part of a mountain of evidence – up to 300 pages and 67 CDs of witness statements, surveillance videos and other material-- expected to be made public soon in connection with the second-degree murder case against Zimmerman.

Zimmerman allegedly shot Martin during a confrontation inside the gated community in Sanford where Zimmerman was a neighborhood volunteer and where Martin was visiting his father’s fiancée.

After first reporting a suspicious person in the neighborhood in a phone call to Sanford police, Zimmerman followed the teenager before a fatal confrontation that remains shrouded in mystery.
