Zimmerman was driving through the gated community where he lived on the evening of Feb. 26, 2012, when he saw Martin walking back from a convenience store to a home belonging to his father’s fiancee. Zimmerman called a nonemergency police number, followed Martin and at some point a fight erupted between them that left Martin dead.

The case is racially charged. A 44-day delay in Zimmerman’s arrest led to protests around the nation. Protesters questioned whether the Sanford Police Department was investigating the case seriously because Martin was a black teen from the Miami area. Zimmerman identifies himself as Hispanic.

Zimmerman is charged with second-degree murder. He is pleading not guilty.
