The suspected Gilgo Beach serial killer Rex Heuermann has been charged with a fourth murder in New York state.
Mr Heuermann, 60, was already charged in July with killing three women more than a decade ago, part of a string of Long Island murders that could have up to 11 victims.
He appeared in court on Tuesday and pleaded not guilty, according to the BBC's partner CBS News.
Mr Heueremann has been held in Suffolk County Jail without bail.
The remains of Maureen Ms Brainard-Barnes, who was 25 when she first vanished, were discovered along Ocean Parkway in December 2010 when authorities were searching for Shannan Gilbert, a sex worker who vanished earlier that year.
Altogether, 11 sets of human remains were found on the same stretch of Gilgo Beach between 2010-11, linked to nine women, one man and a toddler. The identities of four, including the toddler, her mother and the man, remain unidentified.
