As Luis Vega entered his golden years, he did what many seniors do -- applied to the U.S. government for benefits.

The process came to a halt when an investigator for the Social Security Administration found a problem with his paperwork -- a 34-year-old murder warrant.

Vega, 65 and living in New York, has been wanted in Chicago since 1971 for a shooting at a South Side bar that killed a man and wounded another, Chicago Police said. When Vega applied for his benefits, he used the same Social Security number he did when he was living in Chicago 30 years earlier.
