Trayvon Martins father Tracy Martin and mother Sybrina Fulton on March 25 in Sanford, Fla.
(4 of 4)
The Sanford authorities are looking into these questions. The U.S. Department of Justice has launched an investigation into whether Zimmerman violated Martin's civil rights, and a special prosecutor appointed by Governor Rick Scott is examining cell-phone tapes suggesting the two men were struggling violently at closer range than some initial reports suggested. A grand jury is scheduled to convene on April 10.
The case will unfold slowly in court and will offer only agony to Martin's parents. But even if Zimmerman is eventually charged, it should be Florida's gun laws that go on trial.

A previous version of this article asserted that Sanford, Fla. police chose not to take George Zimmerman in for questioning on the night of the shooting, and that this lapse contributed to the administrative leave of Sanford police chief Bill Lee. Recently released video footage indicates that officers did indeed take Zimmerman into custody that night and questioned him; according to reports, police also asked the prosecutor for an arrest but were refused. Lee stepped down over the criticism directed at his department over the handling of the case.
