The State Attorney's Office has released discovery records in the case against George Zimmerman.

Zimmerman is charged with second-degree murder in the February death of Trayvon Martin in a Sanford neighborhood. Zimmerman has claimed he shot Martin in self-defense.

Within the documents was the autopsy report, which shows where Martin was shot and what happened as a result. It also said Martin had THC in his body that night. THC is a substance commonly found in marijuana. However, the report did not specify marijuana.

Also among the documents is the original report on Zimmerman's injuries that night. It stated that Zimmerman had abrasions on his forehead, bleeding and tenderness to his nose, and a small laceration on the back of his head. The records also included close-up pictures of Zimmerman face the night of the shooting.

The records include several recordings and pictures, along with 183 pages of documents.

The documents include the original report by Christopher Serino, the investigator who investigated the shooting. The report said the entire incident, from Zimmerman's initial call to when he was taken into custody, only took about eight and a half minutes.

Among the witness statements is one from a man who said he saw a dark-skinned man in a hoodie who was on top of a Hispanic man and punching him. The man yelled that he was going to call the police, and then he heard a "pop." However, the man admitted that he did not see the beginning of the scuffle. Another witness said he heard someone say "I've got a gun, I've got a gun," and "take my gun from me."

Serino concluded, however, that there was enough evidence to charge Zimmerman was manslaughter.

One of the Sanford police reports concluded the whole incident was avoidable had Zimmerman stayed in his car and waited for law enforcement.

In the report, Serino also said he heard a man's voice yelling either "help" or "help me" 14 times in a 38 second time span on one of the 911 tapes, and that the voice was determined to be Zimmerman.

Another report recounts Tracy Martin, Trayvon's father, listening to the 911 tape. The report said Martin was asked whether the voice on the tape was his son, and Martin "quietly responded 'no.'"

Martin later listened to a cleaned-up version of the tape and claimed it was his son. However, the FBI ruled the call was of "insufficient voice quality and duration to conduct a meaningful voice comparison."

The FBI report also examined Zimmerman's 911 call to determine whether Zimmerman used a racial slur when talking about the suspicious person he was observing that night. There has been some talk over what word Zimmerman said. The FBI determined that the audio quality was too poor.

Meanwhile, DNA forensics of the gun used that night show that Zimmerman's DNA is on the firearm, except for the trigger.

According to the report, another individual's DNA was on the gun, but experts could not identify whose it is.

Zimmerman claimed Martin reached for the gun and that's when he fired.

But there are different descriptions of the gunshot wound to Martin. The Volusia County Medical Examiner said the shot was at a "intermediate range."

However, the FDLE report notes residue from the gun is consistent with a "contact shot."

The medical examiner said the shot punctured Martin's heart and lung.


Martin family attorney reacts

Despite the new evidence of Zimmerman's injuries, the lawyer for Trayvon Martin's family said he doesn't buy it.

Attorney Benjamin Crump weighed in on the new evidence Thursday night on CNN's "Piers Morgan Tonight."

"The family has always said if there was an altercation, that it was started by George Zimmerman," said Crump. "We have heard objective evidence. We have heard the 911 tape that he said 'These "A-holes" always get away.' So we know his state of mind when he got out of that car. We heard him running, chasing Trayvon Martin. We heard him breathing hard. So anything that happened, it was started by George Zimmerman."

"If George Zimmerman would have just done what neighborhood watch is supposed to do, none of this would have happened," Crump continued. "He was neighborhood watch, not a neighborhood cop. If he would have just stood down."

Regardingthe discovery of THC in Trayvon Martin's system, Crump said that is not significant to the case. He said what is significant is that there was no toxicology report done on Zimmerman to see if there were any drugs in his system.
