Neighbors of a man accused of deserting the Air Force and assuming a fake identity for 35 years say he was quiet, pleasant and always wore a San Francisco Giants cap. Residents of the quiet tree-lined street in Daly City, south of San Francisco, said Monday that they were stunned to see news reports identifying their neighbor as William Howard Hughes Jr. The Air Force Office of Special Investigations says Hughes was an officer with top security clearance who disappeared in New Mexico in 1983 and was arrested in California last week.
