New York ( CNN ) -- Aircraft will soon shoot high-resolution photos of the Long Island , New York , beach area where the search for a missing woman has led to the remains of at least eight people . Airplanes and helicopters will begin circling the barrier island beach later this week as federal , state and local search efforts continue , Suffolk County Police Commissioner Richard Dormer told reporters on Wednesday . `` The high-resolution technology should be able to provide a detailed representation of the area and will extend through Nassau County , '' Dormer said . `` We 're hoping the technology will help identify skeletal remains that may still be out there . '' The aerial imagery will supplement police-dog search units , which expected to resume searching later this week . Meanwhile , diver teams are already scouring the waterways on the north side of the barrier island . Eight different sets of confirmed human remains have been found in Suffolk County , Long Island , since December , in what police say could be the work of a serial killer or killers . Additional remains -- including a human skull -- were uncovered Monday . Police have not said whether the latest remains are from different people , or if they could have come from the eight victims . Some of the remains found Monday in a Nassau County wildlife preserve were wrapped in a `` black plastic product '' similar to a plastic bag , a law enforcement source said Wednesday . The remains `` appeared to be part of a lower extremity , '' the source said . Medical examiner investigators are trying to determine the age and sex of the remains and attempt to find out how long they were at the location before being discovered . Federal agents first joined police in their investigation in December , after four bodies had been found . That discovery on a quarter-mile stretch of Oak Beach indicates that `` they were dumped there by the same person or persons , '' Dormer told reporters at the time . `` It 's too coincidental that there were four bodies in the same location . '' They were all found stuffed in bushes along an isolated strip of waterfront property . The grisly find occurred as police searched for 24-year-old Shannan Gilbert , who was last seen alive in May 2010 in the Gilgo Beach area . Gilbert 's sisters said Shannan was an escort who was visiting a client . They said she ran from the man 's house and called 911 , claiming that someone was trying to hurt her . In a strange series of events , a local resident -- who lives a few miles from where the remains were found -- said a young woman who `` looked like she was partying all night '' came to his door at about 5 a.m. on May 1 . `` She was screaming 'Help me , help me ! ' and said somebody was chasing her , '' said Gustav Coletti , who lives in the town of Oak Beach . He described the woman as a `` young , light-brown-haired person in her early 20s . '' Coletti said he called 911 after opening his front door to the woman , prompting her to flee into the weeds along an embankment near his house . Moments later , Coletti said an `` Asian-looking man '' man driving a dark-colored sport utility vehicle pulled up alongside his home , looking for the woman . `` Things got out of hand at a party and I 'm just looking for her , '' Coletti quoted the man as saying . When Coletti told the man that he had called police , the man said he `` should not have done that '' and drove toward where girl had fled , Coletti said . But he says it took police more than four months to question him about the incident , potentially losing crucial evidence over that time frame . Coletti later told CNN that he believes the woman he saw that night was Gilbert . CNN can not independently verify that claim . Dormer said Wednesday that he has `` no idea when the detective spoke to whomever you 're talking about , '' referencing Coletti . Police said they received a written statement from Coletti in June . Gilbert 's body has not been among the remains identified . CNN 's Allan Chernoff and Susan Candiotti contributed to this report .
