Suffolk police Sunday were awaiting a report by the county medical examiner's office on the human skeletal remains found in Manorville.
The report could shed light on whether the remains found last week were connected to other criminal cases. There was no active searching at the site Sunday morning.
Four other sets of human remains have been found in the same area since 2000, including those of two women whose partial remains also were found at Gilgo Beach.
At a news conference Saturday, a day after the Manorville discovery, Suffolk County Deputy Insp. Kevin Fallon said authorities had not determined the age or gender of the newly found remains. He said detectives would review the bones before deciding whether police need to return for another search.
A man and his dog found the remains on woodland that's part of the Upton Ecological and Research Reserve, a protected pine barrens overseen by Brookhaven National Laboratory.
The bones were found 300 feet from North Street on the 530-acre tract, which is north of the Long Island Expressway, police said. They are believed to have been left at the scene at least five years ago, based on the growth of vegetation in the area.
The Manorville location is 4 miles from where the partial remains of Jessica Taylor, 20, of New York City, were found more than eight years ago, near Halsey Manor Road and the Long Island Expressway.
Remains of another woman -- known to authorities as Jane Doe No. 6 -- were found in Manorville on Nov. 19, 2000. Those remains were found in a heavily wooded area about a half-mile west of Halsey Manor Road and north of the Long Island Expressway, police said.
Taylor, Jane Doe No. 6 and eight other sets of remains were found between December 2010 and April 2011 in the Gilgo Beach area.
