Scores of people turned up for Joseph Walker's funeral Monday in Texas — not because they knew him, but because they knew the Vietnam-era veteran was at risk of being buried without anyone in attendance.
Walker served in the U.S. Air Force, and he died of natural causes in November at the age of 72. When the Central Texas State Veterans Cemetery announced funeral plans for him last week, the facility said it didn't expect anyone other than staff members to be present.
