The remains of four more victims of a serial killer have been found behind a shopping centre in Connecticut, where the bodies of three woman were found eight years ago.
Police, who are linking the seven deaths, said the suspect at the centre of the murder investigation is already in prison.
They have not released a name but said there is no threat to the public.
The partial remains of Diane Cusack (53) Joyvaline Martinez (23) and Mary-Jane Menard (40) were discovered in a wooded area in New Britain by a hunter in 2007.
All three women had drug problems, according to police.
Investigators have been returning to the site each year ever since in the search for further victims.
An FBI dog helped to locate the newly-found remains in an area police have referred to as a "burial site".
One of the latest victims has been named as Melanie-Ruth Camilini, a mother of two from Seymour, who like the other identified women had last been seen in 2003.
The case threatens to rival that of Connecticut's most notorious serial killer, Michael Ross, who admitted to murdering eight women and girls in Connecticut and New York in the 1980s and was executed in 2005.
Chief state's attorney Kevin Kane said it was a sad day for the families.
"Now they have some answers, but the answers that they have aren't good, either," he said.
Ms Menard's son, Brian McKinney, said: "It's a relief to know that it's not going to happen again."
Her sister, Anna Santiago, said: "At least we know that pretty soon we will have justice."
In a macabre coincidence, the body of a teenage girl, Elizabeth Honsch, was found behind the same shopping centre in 1995.
A week later, the body of her mother, Marcia Honsch, was found near an entrance to Tolland State Forest in western Massachusetts. Both had been shot in the head.
Police do not believe those killings are linked to the seven women identified as the serial killer's victims.
Robert Honsch has been charged with murder with the murder of his wife and daughter. He has pleaded not guilty and is awaiting trial.
