Investigators are hoping to give a serial murderer's victim from two decades ago a name.

Police released an artist's rendering of a woman whose dismembered body was found in black plastic bags down a Yonkers alley in June 1992.

The woman was missing both arms and a leg, so police were not able to fingerprint her, but her DNA was just put into a national system last year thanks to a blood sample.

The woman was a prostitute who had at least one child, according to police, but they’ve released few other details.

A distinctive butterfly tattoo may help to identify the woman known as the Yonkers Jane Doe.

"She's a person that was just dumped like garbage, and we want to give her an identity, be able to tell the family at least we know what happened to her. You know what, there was a little bit of justice, the person was arrested," says Detective John Geiss, of the Yonkers Police Department.

The woman is believed to have been 28 to 42 years old and was slain by confessed Long Island serial killer Robert Schulman.  Schulman died in prison back in 2006.

In a confession, Schulman said he took the woman back to his house and used crack with her. He claimed he blacked out, and when he woke up she was dead on his floor.

She was among five of his victims.

Anyone who may be able to help identify her is asked to call the Yonkers Cold Case Unit at 914-377-7731.
