(CNN) - A neighborhood watch captain accused of killing an unarmed teen goes on trial Monday, in a case that sparked fresh debate about race relations and gun laws.

George Zimmerman is accused of fatally shooting 17-year-old Trayvon Martin on February 26, 2012, in Sanford, Florida.

Martin was black, and Zimmerman identifies himself as Hispanic.

Zimmerman is charged with second-degree murder. He says he shot the unarmed teen in self-defense.

In a CNN poll released Monday morning, 62% of respondents say the charges against Zimmerman are probably or definitely true.

Opening statements begin Monday and are expected to last several hours.

A jury of six women will decide Zimmerman's fate, which has already drawn some scrutiny from the public about whether he will get a fair trial.

Martin's parents will be in the courtroom, and are expected to deliver a statement before the proceedings begin.
