SANFORD, FL. (NBC) - More evidence was released Thursday in the Trayvon Martin case.
The evidence includes photos of Martin's bloodied sweatshirt and his hoodie with a single bullet hole.
According to the documents, scientists noted a layer of soot around the bullet hole as clear evidence he was shot at very close range something George Zimmerman claims was necessary to save his own life during an altercation with Martin.
Also in the evidence release are several phone calls made to Sanford police to report suspicious activity in the six months leading up to his encounter with Martin.
"We've had a lot of break-ins, suspicious characters hanging out, loitering," Zimmerman tells the dispatcher.
In most of the calls, Zimmerman speaks in a matter of fact tone about a suspicious man picking through garbage or a garage door left open, but on the rainy night of his encounter with Martin, Zimmerman sounds more urgent.
"Now he's coming towards me. He's got his hand in his waist band. Something is wrong with him. He's coming to check me out," Zimmerman says.
