ORLANDO, Fla. – Murder defendant George Zimmerman could have defused the deadly confrontation with Trayvon Martin if he would have identified himself as a member of neighborhood watch and he passed two lie detector tests when questioned by investigators, according to a report released Tuesday.

More documents in the second-degree murder case against the 28-year-old were released that included investigators' accounts of the night of Feb. 26, when Zimmerman killed Martin after following the unarmed teenager through a gated community in Sanford. He has pleaded not guilty and has said from the night of the fight that he feared for his life because Martin was beating him up before Zimmerman grabbed his gun in his holster and shot the 17-year-old.

Sanford detective Christopher Serino said in the report that Zimmerman at first verbally confronted Martin from his car and that the defendant and witnesses said he was too afraid of Martin to get out. Later in the encounter, Zimmerman got out of his SUV and followed Martin.
