(CNN) — Self-defense or murder?

That’s the question at the heart of the trial of George Zimmerman, a neighborhood watch volunteer who killed 17-year-old Trayvon Martin.

Monday marks the start of jury selection in Seminole County, Florida, where Martin was fatally shot on February 26, 2012.

The shooting put a national spotlight on Zimmerman’s hometown of Sanford and sparked fresh debates about race relations and gun laws in America.

Zimmerman is Hispanic; Martin was African-American.

An initial decision not to pursue charges against Zimmerman led to the dismissal of the town’s police chief and the appointment of a special prosecutor, who accused the neighborhood watch volunteer of unjustly profiling and killing Martin.

Zimmerman now faces a second-degree murder charge in Martin’s death. He has pleaded not guilty and is currently free on $1 million bond.
