Zimmerman was released around midnight Sunday from a county jail. He was wearing a brown jacket and blue jeans and carrying a paper bag. He met a man in a white BMW and drove away. His destination was unknown and was being kept secret for his safety. Some speculate it could be outside Florida.
As he walked out of the county jail, Zimmerman gave no statement to reporters.
Circuit Judge Kenneth Lester said at a hearing Friday he cannot have any guns and must observe a 7 p.m.-to-6 a.m. curfew. Zimmerman also surrendered his passport.
Zimmerman, 28, fatally shot 17-year-old Trayvon Martin during an altercation on Feb. 26 inside the gated community where Zimmerman lived.
Martin was walking back to the home of his father's fiancé when Zimmerman saw him, called 911 and began following him. Investigators said a fight broke out, but it's unclear who started it.
To post bail, Zimmerman had to put up 10 percent, or $15,000. His father had indicated he might take out a second mortgage.
