( CNN ) -- Prosecutors released a summary of evidence Tuesday in the case against neighborhood watch volunteer George Zimmerman , who is accused of second-degree murder in the death of Trayvon Martin . The eight-page document released to the public contains a list of possible witnesses and law enforcement reports that could be used in the prosecution 's case against Zimmerman . But it does n't include details from those statements or reports , and contains no new revelations about the case , which sparked nationwide protests and reflection on race relations and gun laws in the United States . The document is part of the routine exchange of information between prosecutors and defense attorneys that occurs before trials . Defense attorney Mark O'Mara said Monday on the website set up to release information from Zimmerman 's side that his office had received `` 67 compact discs and numerous hardcopy documents '' from prosecutors , including many of the records and statements mentioned in the summary . `` Please remember and understand that it is inappropriate for us to comment on particular pieces of evidence , '' O'Mara said in the website statement . Zimmerman , 28 , is accused of killing Martin on February 26 as the African-American teenager walked back to the Sanford , Florida , house where he was staying , after visiting a convenience store . Prosecutors have said Zimmerman , who is a white Hispanic , killed Martin unjustly after profiling him . Zimmerman , who acknowledges shooting Martin but claims self-defense , has entered a not guilty plea in the case , which has not yet been scheduled for trial . A timeline of the case against George Zimmerman . The document lists 50 possible law enforcement witnesses , including 28 officers from the 140-member Sanford Police Department . It also lists 28 civilian witnesses , including Martin 's brother , mother and father , two of Zimmerman 's friends -- Joe Oliver and Frank Taffe -- and his father , Robert Zimmerman . Prosecutors did not give names for 22 other potential civilian witnesses . Attorneys have previously expressed concern about publicly identifying some witnesses who may fear retribution for their roles in the case , which has inflamed passions among supporters of both Martin and Zimmerman . At least one of the witness interviews was conducted by Martin family attorney Benjamin Crump , according to the document . Evidence taken from Zimmerman after the shooting , including his weapon , bullets , clothes , a DNA sample , medical records and his cell phone data were also included in the disclosure to defense attorneys , according to the document . The document indicates that police technicians in biological and DNA evidence , trace evidence , gunshot residue , fingerprints and firearms may testify , along with two FBI agents , as well as two audio technicians who analyzed emergency calls made during the confrontation between Zimmerman and Martin in an effort to determine who was heard screaming in the background . Experts Tom Owen and Edward Primeau concluded that the screams did not come from Zimmerman , who told police that Martin rushed him after they exchanged words , knocked him to the ground and repeatedly hit his head against the concrete sidewalk . Martin , who lived in Miami , died after a chance encounter with Zimmerman in the gated community where he was staying with his father during a suspension from school . Zimmerman called police to report a suspicious person walking on the streets of the neighborhood , which had been struck by several burglaries in recent months . Prosecutors say he disregarded a dispatcher 's advice not to follow the person , who turned out to be Martin , and shot him after a confrontation minutes later . While Zimmerman supporters have characterized him as a well-meaning neighborhood watch volunteer who was only trying to protect his community , Martin 's family and supporters have said he unfairly profiled Martin as a troublemaker just because he was an African-American teenager walking down the street wearing a hoodie . Sanford police initially declined to arrest Zimmerman , saying there was no evidence to contradict Zimmerman 's claim of self-defense under Florida 's `` stand your ground '' law , which allows people to use deadly force anywhere they feel a reasonable threat of serious injury or death . After weeks of protests demanding Zimmerman 's arrest , a special prosecutor appointed by Florida Gov . Rick Scott filed the second-degree murder charge against Zimmerman . He was arrested April 11 and briefly jailed . He has returned to hiding after his release on $ 150,000 bond .
