Suffolk County Police Commissioner Richard Dormer on Tuesday is expected to announce the results of a months-long effort to produce composite drawings of some of the five remaining unidentified people whose remains were found along Ocean Parkway, according to a source familiar with the department's investigation.

The images Dormer is expected to unveil at a news conference at police headquarters in Yaphank are renderings of what the victims may look like.

Dormer is also expected to show photographs of jewelry and clothing found near the remains, to help with identification.

Suffolk officials did not return calls seeking comment on the briefing, scheduled for 11 a.m.

Massive searches of the area near Gilgo Beach over the past 10 months have yielded the remains of at least 10 people. The identities of five of them are still a mystery.

Those include:

A woman whose body parts were found both in Manorville in November 2000 and Ocean Parkway in April.

A girl believed to be between 18-24 months old whose skeletal remains were found wrapped in a blanket in April.

A young man whose remains showed signs of trauma and whose body was discovered in April.

Two other sets of remains found in April near Jones Beach in Nassau County.

The remains of Megan Waterman, 22, of Scarborough, Maine; Melissa Barthelemy, 24, of the Bronx; Maureen Brainard-Barnes, 25, of Norwich, Conn., and a fourth woman, Amber Costello, 27 of North Babylon were found last December wrapped in burlap and dumped near Ocean Parkway. All four had worked as prostitutes, police said.

The search for another woman, Shannan Gilbert, 24, prompted the discovery of the four women. Authorities have since found the remains, some dismembered or incomplete, of six other people, although their deaths are not believed to be associated with the four found in December. One was identified as Jessica Taylor, 20, of Manorville.
