Authorities said Thursday that they found more bones at the same National Grid property in Everett where human remains were found by workers earlier this month.

The Middlesex District Attorney’s office told NECN that their preliminary investigation suggests that the remains belong to the same woman they’ve been trying to identify since the initial discovery on July 7.

The facility is located on Rover Street in an industrial area. 

According to an analysis at the time carried out by a forensic anthropologist, authorities believe the woman was deceased from one to five years before her remains were discovered.

Other signs suggest the victim was a woman between 26 and 52 years of age, most likely white, with an estimated height of anywhere from 5 feet 1 inch to 5 feet 9 inches tall, investigators said. The victim also had previous injuries and medical procedures, including a broken lower leg, a broken nose and restructuring, along with some tooth loss and reconstruction.

Authorities said the woman wore Sporto Boots, ankle height, Daria style, size 10m; a long-sleeved white T-shirt; and Cocoa vintage, black fleece sweat pants, size small.

Anyone with information they believe could help the investigation is encouraged to contact the Massachusetts state police assigned to the Middlesex D.A.’s office at 781-897-6600 or the Everett Police Department at 617394-2367.
