More details are emerging on the autopsy results for Trayvon Martin, and earlier reports that his knuckles were skinned (as if from a fight) seem to have been inaccurate. The autopsy reported only a tiny abrasion about a quarter-inch long on his left ring finger.

And possibly even more interesting: the autopsy report says Martin died from a gunshot at “intermediate range.”

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.
