Heidi Balch, 25, of New York City, was likely done in by serial killer Joel Rifkin, authorities say.
DNA helped authorities identify a severed head found on a New Jersey golf course in 1989 as a New York City woman who may have died at the hands of a serial killer.
Authorities say 25-year-old Heidi Balch was HIV-positive and worked as a prostitute.
Authorities believe she was killed and dismembered by Joel Rifkin, who is serving more than 200 years in a New York prison for nine murders. He claimed he killed 17 prostitutes and his first victim went by a name that Balch used.
Authorities used the alias to track down relatives, which led to the DNA match.
Hopewell Police Chief George Meyer tells The Times of Trenton that New York authorities have no interest in prosecuting the case because Rifkin is already behind bars for 200 years.
