New clues have emerged in the case of the Long Island Serial Killer, PEOPLE has learned.

DNA links a woman’s torso found in 1997 in Nassau County, New York, and the body parts of a woman whose remains were found years later on Gilgo Beach in Suffolk County, New York.

The link, showing the torso belong to the unidentified female victim known as “Peaches,” is according to information in the federal National Missing & Unidentified Persons System.

Both the woman and her toddler child, who were found dead in April 2011, are believed to be victims of the Long Island serial killer or killers, who authorities believe left more than ten people dead — mostly women. The victims’ bodies were found in the Gilgo Beach area on Long Island.

No suspects have ever been identified.

The revelation surfaced earlier this month, the week of the sixth anniversary that remains of the suspected serial killer were first found.

While authorities already knew that the DNA between remains found at the two sites were linked, that information was never entered into the national government database until Dec. 8, J. Todd Matthews, Director of Case Management and Communications for NamUS, tells PEOPLE.

“This was not a new scientific breakthrough but new information that a lot of people didn’t know,” Matthews says.

Suffolk County police had discovered the torso of the woman, identified as Jane Doe No. 3, on April 11, 2011, on Gilgo Beach.

That victim is believed to be the mother of Baby Doe, a young girl between the ages of 16 and 32 months old whose remains were found near Cedar Beach  on April 4, 2011.

The case file for Jane Doe No. 3, who came to be known to investigators as “Peaches” because of a peach-shaped tattoo found on the remains, had been in the system since Oct. 3, 2013, Matthews says.

When NamUs received a recent inquiry about whether information about extremities discovered in Nassau County were in the database, Matthews learned that yes, that information had already been entered on Dec. 8
