Munguia was last seen around 01. 00 on May 28, 1981 when she left home to visit a friend in Oklahoma City, Oklahoma. Munguia's vehicle was found abandoned at the Will Rogers World Airport in Oklahoma City, Oklahoma on November 14, 1981. It was determined that her vehicle had been in the parking lot for a minimum of eighty days. Her family do not believe Judie Munguia would have ever just walked away, leaving her then 11 year old son behind. Foul play is possible.
