It is not clear what effect the affidavit's conclusion will have on the federal investigation. Martin was black. Zimmerman's father is white and his mother is Hispanic.

When a recording was released of a 911 call George Zimmerman made to police shortly before fatally shooting Trayvon Martin, some who heard it zeroed in on three words to suggest he had uttered a racial slur.

An affidavit released by the prosecutor who has charged Zimmerman with second-degree murder says he did not use a slur, however. The document filed Thursday did say Zimmerman "profiled" Martin. It did not elaborate.

Some cited the alleged slur as potential evidence for the U.S. Justice Department, which could still bring a hate-crime charge against Zimmerman. And it fed growing outrage over the police department's initial decision not to arrest Zimmerman.
