Zimmerman admits to killing Martin on Feb. 26, 2012, but says he did so in self defense. When Zimmerman reported Martin to a non-emergency dispatcher he was told not to follow the teen and that they were sending a car. What happened next remains unclear.
Zimmerman claims that he did not follow the teen and that Martin confronted him and knocked him down. He claims Martin banged his head on the sidewalk several times and that the two struggled over Zimmerman's gun until he pulled the trigger.
Nelson ruled Friday that when opening statements begin, prosecutors will be able to tell the jury that Martin was profiled by Zimmerman, but that they should avoid characterizing the profiling as "racial." They can also say Zimmerman was a "wannabe cop," use the word "vigilante" and say that he confronted Martin.
