Found! Accused Scammer Stanford Turns in Passport in Washington

The billionaire banker accused of scamming $8 billion, R. Allen Stanford, was located by FBI officials today and served with civil papers by the SEC, putting an end to a nationwide search.

Stanford later turned in his passport to federal prosecutors, saying "he would not flee," according to one of Stanford's lobbyists, Ben Barnes.

Watch the full story tonight on World News with Charles Gibson at 6:30 p.m. ET.

Stanford was located in the Fredericksburg, Virginia area, the FBI said in a statement. The papers he was served with were the SEC's complaint, the memorandum of law filed with the complaint, the court order freezing his asset, and the court order appointing a receiver, according to a SEC statement.

Stanford is "very depressed," according to Barnes and sought to end a federal manhunt for him by directly approaching officials at the Justice Department, Barnes said.
