Gifford had moved to San Francisco in the summer of 1976 to live with her father, his wife and her two half-siblings. Shin was 6 at the time, and his sister was much younger, the San Francisco Chronicle reported.

After learning that Gifford's paternal aunt lived in Southampton, New Jersey, the San Francisco Police Department enlisted the assistance of the New Jersey State Police Missing Persons Unit Detective.

In June, New Jersey authorities met with Gifford's aunt, Ogee Gifford, to obtain a DNA sample and gather photographs and dental records. One of the photographs showed Gifford wearing the necklace that was found with her remains, police said.

Ogee Gifford did not change her phone number for more than four decades in case her niece ever called, police said.

The California Department of Justice announced that the remains were positively identified as Gifford through DNA and photographs last month.

San Francisco Police are now trying to determine who killed her, the San Francisco Chronicle reported.
