Nuno was last seen leaving work in Cedar Hill, Texas on May 31, 2005. That same day, Nuno called a coworker and said she had been kidnapped. She has never been seen again. Authorities believe she was taken against her will.

Two weeks after her disappearance, Nuno called her parents and said people should stop looking for her. She refused to speak in English during the conversation, refused to say whether she was still in the United States, and did not confirm that she was all right. Investigators will continue to search for her until they have verified her well-being.

Nuno may be in the company of a Hispanic male in his early twenties. She may be traveling in a green Honda or a black mid-1990s Chevrolet truck with 20-inch wheels and flames painted on the sides. She may be in Mexico or in the Miami or Pensacola areas of Florida. Nuno has three children. Her case remains unsolved.
