Forensic cops have dug up mysterious objects in the backyard of Gilgo Beach serial killer suspect Rex Heuerman.
The haunting footage shows officers crowding a hole in the ground as they survey what appear to be small pieces of dirt on a board.
Some experts speculated that they could be human remains, while others warned that they could be animals or something else.
Investigators have been digging through boxes of belongings from the home for the past two weeks as they desperately search for any evidence linked to the infamous murder.
They discover a large cache of guns and investigate the idea that some of the victims may have been killed in the home.
Heuerman, 59, was arrested on July 14 on suspicion of murdering three sex workers found in Gilgo Beach in 2010.
Forensic investigators were seen photographing objects found at Rex Heuerman’s Long Island home on Monday. Analysts told Newstimesuk.com that they could be human remains, but would require further investigation.

This week’s exclusive Newstimesuk.com photos show investigators looking at a tray of objects, which experts say could be human remains.
Heuerman, 59, was arrested July 14 in Manhattan, where he owned an architecture firm. He has been charged with three murders in Gilgo Beach
Forensic policemen are seen surveying items placed on a white board around an excavator bucket.
After the photo was taken, someone stood nearby with a large sack to carry the items.
A doctor and a bone expert analyzed the photos for Newstimesuk.com and were divided over the nature of the object – but said ‘human remains cannot be ruled out’.
‘From a real distance they must be human or animal. But it is far from knowing for sure,’ said a doctor.
‘DNA testing is essential: we doctors are used to close-ups.’
Another expert, a forensic anthropologist, told Newstimesuk.com: ‘From my experience, they look very rectangular like humans. I would not immediately recognize any of these objects as human remains.
‘But the black spot on them suggests we’re looking at organic material, and the context in which they were found means I wouldn’t rule out human remains.’
The yellow digger has been at home on Long Island since Sunday
On Monday the limp items were placed in a brown bag and taken for further analysis
Investigators spent a significant amount of time looking inside Human’s basement, the door of which can be seen propped open by his plants
The site was excavated by machine and hand on Monday: men with spades could be seen standing at the edge of the pit
Discoveries are recorded on a tablet after photography
The search for the site could be over by Tuesday
A yellow excavator is seen Monday outside Massapequa Park, the Long Island home of Rex Heuerman.
Suffolk County Police Commissioner Rodney Harrison told News 12 Long Island investigators could not confirm if any of the victims ever visited Heuerman’s home.
“We’re doing a full investigation around the house to see if there’s anything we need to take a closer look at,” he said Monday.
‘Can we confirm that someone was killed inside the house? We cannot confirm that at the moment.’
Harrison said Human’s basement room was not soundproof but confirmed it had extremely thick walls.
Harrison said it may have been used to store his large collection of guns.
More than 200 firearms were found in his suburban Massapequa Park, Long Island, home — even though he only had a permit for 92, according to prosecutors.
The first victim, Melissa Barthelemy, 24, was discovered by Suffolk County police on Dec. 11, 2010. Megan Waterman, 22, was found two days later.
Maureen Brainard-Barnes was 25 when she disappeared (left). Amber Lynn Costello was 27 years old. Their bodies were found near Barthelemy on the same day

Police said they believe the accused killer killed at least one of her victims inside the home
A former colleague of Heuerman told The New York Post the architect took time to install the concrete-lined room.
‘It’s not just a hidden room – it’s a serious vault,’ said the colleague.
‘It had a huge, heavy-duty safe door. He went and poured new concrete walls, lots of concrete to surround this house. It was maybe two or three feet thick.’
Police believe Human’s wife, Asa Ellarup, 59, and children were not involved in the murder.
An analysis of phone records showed Ellarup was out of town in 2009 and 2010 when Melissa Barthelemy, Megan Waterman and Amber Costello disappeared.
He was in Iceland, where he was born, and visiting friends in New Jersey.
Heuerman is also a suspect in the 2007 death of Maureen Brainard-Barnes, but phone records from that era are no longer accessible.
Harrison said Heuerman’s family was shocked when they were told of the alleged crime.
‘They were upset. They were embarrassed,’ he said. ‘So if you ask me, I don’t believe they knew about this double life that Heuermann was living.’
Ellerup filed for divorce last week, and has not returned to the home, which remains closed.
Harrison said the search of the home could end as soon as Tuesday.
‘I’d like to believe we’ll be finished by tomorrow or the end of this week’.
