George Zimmerman, the neighborhood watch captain who shot 17-year-old Trayvon Martin to death in February, is in custody, a law enforcement source has confirmed to NBC News.

NBC’s Kerry Sanders said the source confirmed that Zimmerman, 28, who will be charged criminally for the shooting by Florida state attorney Angela Corey, was picked up by authorities, but the source did not say where or at what time.

Corey will make an announcement about the charges at 6pm EST.

NBC News can also confirm that Zimmerman has a new attorney, Mark O’Mara. O’Mara is an Orlando criminal and family law attorney who, like Zimmerman’s former attorney, Hal Uhrig, was a local TV analyst during the Casey Anthony trial.

Uhrig and Zimmerman’s original lawyer, Craig Sonner, withdrew from the case on Tuesday, saying they had lost contact with their client.

TheGrio will have updates on this story as they develop.
