US Citizen Kidnapped in Nigeria Returns to US A U.S. citizen kidnapped by gunmen in Nigeria's oil-rich southern delta has returned to Georgia after being held captive for a week. Tamara Lane says her brother-in-law William Gregory Ock arrived in Atlanta on Sunday morning. American officials say the 50-year-old was kidnapped on Jan. 20. But they did not offer any details, citing privacy rules. Lane said that a big crowd greeted Ock at the airport and that he "looks great." She says the family wanted to thank people for their prayers and thoughts. The attack occurred outside a bank in Warri, where oil companies pump 2.4 million barrels of crude oil a day. A police spokesman said the gunmen attacked Ock as he came outside, shooting his police escort to death before abducting him.
