Prosecutors are releasing more documents in the case of the neighborhood watch leader charged with fatally shooting Trayvon Martin.
The documents being released Thursday include reports from the FBI and the Florida Department of Law Enforcement.
The FBI is conducting a probe into whether there were civil rights violations in the handling of Martin's death investigation, and the FDLE assisted the criminal investigation.
Former neighborhood watch leader George Zimmerman is charged with second-degree murder in the 17-year-old Martin's death. He is claiming self-defense.
Zimmerman and Martin got into a fight last February in a gated community in Sanford, Fla., a suburb of Orlando.
The lack of an arrest for 44 days led to protests nationwide and the departure of Sanford's police chief.
