Mellin was employed by a Department Store in the Buenaventura Shopping Center. She left work shortly after closing on the night of January 20, 1970. She was last seen standing next to her car in the shopping center parking lot while an unidentified male changed her tire. When she failed to return home that night, her father went to the shopping center looking for her and found her car still up on a jack with the flat tire still attached (Information retrieved from NamUs.gov)
