Zimmerman Free After Posting Bail

George Zimmerman, who has been charged with 2nd-degree murder in the death of Trayvon Martin, has been released on bail.

Zimmerman, 28, admitted shooting 17-year-old Trayvon on Feb. 26 as the unarmed youth walked along a gated community in Sanford, Fla.

Zimmerman was seen leaving the John E. Polk Correctional Facility in Sanford over the weekend, headed for an undisclosed location. The neighborhood watch guard will remain in seclusion and out of touch with his family. He will also have to wear an ankle monitoring device.

Following a bond hearing on April 20, Zimmerman's family came up with the required $15,000 of his $150,000 bond, and will be free from jail until his trial.

Zimmerman offered his apologies to Trayvon's family, saying:

"I wanted to say I am sorry for the loss of your son. I thought he was a little bit younger than I was, and I did not know if he was armed or not."
