**UPDATE: George Zimmerman has been charged with second-degree murder.
(CNN) -- George Zimmerman is in Florida and has surrendered to the state Department of Law Enforcement, his lawyer told CNN legal analyst Mark NeJame.
Zimmerman, who has said he fatally shot Trayvon Martin in self-defense, "was out of the state of Florida, as I understand it, for his safety," NeJame said, quoting attorney Mark O'Mara.
Earlier, a senior law enforcement source familiar with the investigation told CNN that Zimmerman "will be (criminally) charged, if he hasn't been charged already,"
Special prosecutor Angela Corey said she will present new information about the case at 6 p.m. ET in Jacksonville.
Martin, 17, was killed February 26 as he returned to his father's fiancee's house in Sanford after picking up candy and an iced tea at a nearby convenience store.
