So little information, I can’t find any articles about her disappearance. What school, what time, car description, living with mother or father? Hopefully there is more information somewhere.
Ancestry has her mother as Azalea V Komlenko, arrived in America 1951 from Manila Philippines
Name: Azalea V Komlenko
Estimated Birth Year: abt 1939
Marriage Date: 6 Sep 1957
Marriage Place: San Mateo, California, USA
Spouse: John R Hockenson
Spouse Age: 21
John Richard Hockenson deceased 2002.
He had lived in Florida Miami from a marriage record in 1975, if I have the correct John R Hockenson.
From Ancestry she has a brother (from that marriage) born 1962.
