Authorities were searching for a missing woman just outside Gilgo Beach Sunday.
While some dozen official vehicles were at the scene at one point, including the Suffolk Marine Bureau, state troopers and several unmarked police cars, the Nassau County Police Department is the lead agency on the investigation, because the items were found in Nassau, said a Nassau police spokeswoman.
As of Sunday night, the woman, whose identity has not been disclosed so far, had not been found, Nassau police said.
A New York Police Department spokesman said Sunday night the department was unaware of the identity of the missing woman, but would work with Nassau and Suffolk police during the course of the investigation.
Nassau police said there is no connection between this case and the discovery of 10 sets of human remains in the Gilgo Beach area from December 2010 to April 2011.
The remains included those of a man, a female toddler and eight women -- five of whom were later identified as prostitutes.
The killings are still unsolved, despite ongoing investigations by Suffolk police and numerous theories about whether one killer or numerous killers were involved in the deaths.
"There is no association; the only common denominator is the beach," said Nassau police spokeswoman Maureen Roach.
