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.

A man’s tattooed arm was found in Babylon, LI.

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.

What we know about the body parts found on Long Island

On Thursday, February 29th, a girl found a severed arm while walking to school in Babylon near Southards Park with a group of friends, leading to a police search that found multiple other dismembered body parts.

A police dog sweeping a wooded area discovered a disembodied leg “sticking out of a pile of leaves” about a mile from the initial discovery.

The cadaver dog then found a right severed arm “about 20 feet further into the woods from where the left arm [was found], almost in a direct line,” Detective Lt. Kevin Beyrer said. 

Police found two severed heads in the same park later that day, prompting speculation that the Long Island gang MS-13 could be responsible.

One of the heads, as well as a right arm and leg, are believed to belong to the same female victim, while the other head and two arms appear to be from the same man, according to law enforcement.

Fingertips were missing from the man’s arm, which “could mean the victim has a record and [that the perpetrators] don’t want him identified [through prints] because [that] could lead investigators to his killer,’’ a source said.

Four people – Steven Brown, 44, Jeffrey Mackey, 38, and Amanda Wallace, 40, of Amityville and Alexis Nieves, 33, who police say is homeless – were charged with hindering prosecution, tampering with physical evidence and concealment of a human corpse.

Brown, Mackey and Wallace are all listed as residents of a Railroad Avenue home in Amityville that was raided as part of the investigation.

They are accused of removing “sharp instruments, multiple body parts, and other related items” from the house some time between Feb. 27 and March 4, according to charging documents against Wallace and Nieves obtained by The Post.

The foursome is due in court on Tuesday.

“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.
