More bones and clothing were found at the same National Grid property in Everett, Massachusetts, on Thursday where human remains were discovered earlier this month.
The Middlesex County District Attorney's Office says their preliminary investigation suggests the remains are from the same woman whose remains were found on July 7.
Thursday night, detectives were still moving dirt with a front end loader, raking through it with the hope of unearthing more bones or clues.
The woman is believed to have been buried in the shallow grave for one to four years.
"They appear to be a female between the ages of 26 and 52 and ancestry indeterminate, but most likely white, estimated to be between 5'1 and 5'9 in height," said DA Marian Ryan.
The death is considered suspicious.
Thursday, necn spoke with Criminologist Jack Levin Thursday.
He says investigators will be looking into DNA testing to find out who she is.
"Of course that assumes that her DNA was in a database, and that is often not the case, it may or may not be possible for the authorities to know who this victim is," said Levin.
Investigators says the woman had lots of cosmetic work done to her teeth and a metal plate in her left leg.
Levin said the metal plate may be used to identify her, and says he wouldn't be surprised if the dental records were more important than DNA in that respect.
The power company uses the industrial site to process soil and construction debris.
There's not many people nearby otherwise.
"The killer was pretty skillful that he or she decided to move the body to a dump site where the body wouldn't be found over a long period of time," said Levin.
The site is also 300 feet down from an area that's expected to see tremendous development from the Wynn casino that will be built.
The woman's identity is unknown, and the Middlesex DA is asking anyone with information to call state police at 781-897-6600 or Everett police at 617-394-2367.
