Four in custody as more body parts discovered scattered on LI — after 2 heads found: sources

Four people were in custody after severed body parts of a man and woman were found scattered on Long Island last week — as authorities unearthed more remains, sources told The Post.

The collars came Tuesday, after cops raided a home on Railroad Avenue in Amityville late Monday, sources and neighbors said.

Although cops didn’t find any human remains at the home, they found more dismembered limbs hidden in Bethpage State Park and miles away in a wooded area of West Babylon, the Suffolk County Police Department said in a statement Tuesday.

Authorities believe the newly discovered remains belong to the same two people whose body parts were uncovered Feb. 29 in Southards Pond Park in Babylon, the release said.

Cops haven’t publicly identified the victims, but said in the release that the assortment of limbs belong to a 59-year-old woman and a 53-year-old man, both of whom lived at the same address in the city of Yonkers in Westchester County.

“Based on the investigation, this appears to be an isolated incident with no threat to the public,” the release added.

“The investigation is continuing. “

Police did not mention a possible motive for the killings.

But sources told NBC New York that authorities are looking into whether the murders were linked to a possible love triangle.

The first body part was found Thursday morning by a girl walking to school with a group of friends on Siegel Boulevard — which is on the east side of Southards Park in Babylon, Suffolk County.

On Monday night, battering ram-wielding officers busted through the front door of one of the units on Railroad Avenue sometime around 10:30 p.m., a neighbor told The Post.

“There were detectives and police going into my neighbor’s house, so I came over to see what was happening,” she said.

“They had bashed in the door, and there were a bunch of people standing inside the house, cops talking to my neighbors. They had already taken some people away.”

She said she doesn’t know much about the neighbors in question, except that they’re renters who work nights and brought a number of occupants with them.

“Cops were here all night,” she told The Post.

“I watched as long as I could stay awake, and when I woke up in the morning, they were all still here.

“One of them finally told me what they were looking for [and] what this was about,” she said.

“I was terrified. I just stopped asking questions.”

The girl on her way to school called her dad after spotting a dismembered left arm in the bushes.

Her father went to the scene, then called the cops to report the stomach-turning discovery, according to sources.

Officers swept the area in a gory hunt, and eventually turned up more limbs and the two unattached heads.

None of the remains appear to have been in the park very long, police said Friday.

“Preliminarily, it appears it’s a matter of a small amount of days, if not hours,” Suffolk County Detective Lt. Kevin Beyrer told reporters Thursday night.

One of the heads — as well as a right arm and leg — are thought to belong to the same female victim, law enforcement sources told The Post.

The other head, as well as two arms, seem to be from the same man, they added.

The man’s tattooed left arm — which is missing fingertips — could mean the victim has a record, according to sources.

Perhaps his killers didn’t want him identified through his fingerprints, because that might lead authorities to them, a source said.

Police hope the tattoos will help identify him.
