Investigation finds 10-year Arizona officer in U.S. illegally PHOENIX, Dec. 12 (UPI) -- An Arizona state police detective has resigned following revelations she was born abroad and brought into the country illegally when she was young. Carmen Figueroa became an Arizona highway patrol officer 10 years ago and then a detective in 2010, but was forced to either resign or face firing after a State Department investigation found she was living in the United States illegally, CNN reported Thursday. The State Department was investigating Figueroa's brother after he applied for a passport while he was in the Air Force. The brother was flagged over his citizenship status. "When she was informed by the State Department that she and her brother were not U.S. citizens, that was the first she'd heard of it," said Bart Graves, a spokesman for the Arizona Department of Public Safety. Her mother had told her she was born in this country. The Department of Public Safety placed Figueroa on paid administrative leave in September during the investigation until Monday, when she resigned, Graves said. The State Department is not seeking to press charges against Figueroa, Graves said.
