The remains of 'Asian Doe' were recovered along Ocean Parkway in April 2011.
LONG ISLAND, New York -- Even though there has been an arrest in the killings along a coastal stretch of in New York's Long Island more than a decade ago, a string of deaths known as the Gilgo Beach killings, investigators are still trying to solve cold case murders.
On Monday, Suffolk County District Attorney Ray Tierney released three new sketches of another Gilgo Beach victim known as "Asian Doe."
The Asian male victim's remains were recovered along Ocean Parkway in April 2011. However, authorities say Asian Doe was killed during or prior to 2006.
There is a sketch that was previously released in the investigation, but on Monday, three other images were released.
Tierney said the male was believed to be between the ages of 17 and 23.
"He was a teenager or very young adult when the murder occurred," Tierney said. "This victim suffered a violent death."
They were killed by blunt force trauma to the head.
Asian Doe was wearing exclusively women's clothing, including a bra.
That has led investigators to believe that this victim identified as a woman, and worked as a sex worker.
They are of Southern Chinese descent, specifically Han Chinese.
"This person had a name, this person had family, this person had friends," Tierney said.
Authorities did not announce any new charges against Rex Heuermann, the architect and father who has pleaded not guilty to killing six women.

Investigators found 10 other bodies in the search for missing sex worker Shannan Gilbert on a stretch of beach along Long Island's South Shore.
He was first charged with the deaths of women known as the "Gilgo Four" -- Melissa Barthelemy, Megan Waterman, Maureen Brainard-Barnes and Amber Costello -- whose bodies were found covered in burlap in December 2010, according to court records.
Earlier this year, investigators charged Heuermann with the murders of two more women -- the 2003 murder of Jessica Taylor, whose remains were found on Gilgo Beach and in Manorville, and the 1993 murder of Sandra Costilla, whose remains were found in North Sea, Long Island, in 1993.
Heuermann has pleaded not guilty to their murders.
