Mildred Jo Ann Knighten was 15 when she vanished from Pasadena, Texas after leaving her family’s home on the evening of Friday, October 20, 1972, reportedly with an unidentified friend to visit her sister in La Porte. She never arrived. Early Monday morning, October 23, her body was found in a ditch in an industrial area off Texas 225 near a pipeline construction site; some records list October 22 as the date of death. Relatives identified her shortly afterward.

Investigators traced her last known movements to that Friday night departure and the unnamed companion, but no name was publicly confirmed and no arrests were announced.

Who remembers Mildred’s last evening or the person who gave her a ride between Pasadena and La Porte?
