Barbara Glueckert was 14 when she vanished after attending a rock concert in Huntley, Illinois, on August 21, 1976. That evening she had met a man who called himself Tom Edwards and later accepted a ride in his brown Buick Electra 225 to the farm concert; she and a friend became separated during the event and Barbara never returned home.

The man who used the name Tom Edwards was later identified as Thomas G. Urlacher, then in his mid-twenties with a criminal history involving violence against women. Urlacher moved to San Francisco days after Barbara disappeared. In December 1976 he wrote a 33-page letter confessing to raping a girl and saying he had put a girl in the ground; the unsigned letter was turned over to San Francisco police. Urlacher was arrested on an Illinois warrant for contributing to the delinquency of a minor but was never criminally charged in association with Barbara’s disappearance. A 1978 civil suit found him liable for her wrongful death and ordered damages; Barbara was declared legally dead in 1984.

The investigation included hundreds of interviews, scuba searches of lakes and quarries, and land searches by a Green Beret unit, but no criminal indictment followed. Anyone who knew Barbara, attended the Huntley concert, or has information about the brown Buick Electra 225 is asked to come forward.
