George Zimmerman, the man at the center of a high-profile murder case that has stirred racial unrest, is now free on bond.

Zimmerman left a Florida jail at around midnight, two days after a judge set his bail at $150,000.

He's charged with second-degree murder in the Trayvon Martin case. Zimmerman maintains he shot the unarmed 17-year-old in self defense.

He also apologized to Martin's parents in his bail hearing last week.

ABC News released a new photo from the night of the shooting, which appears to show the back of Zimmerman's head covered in blood.

The photo could be used as evidence to support his claims of self defense.
