Long Island body parts murder mystery: Two women and two men are released without bail after being charged with concealing a corpse as identities of victims remains unknown

Four suspects were released without bail on Wednesday afternoon after being charged with concealing a human corpse and tampering with evidence 

Steven Brown, 44, Jeffrey Mackey, 38, Amanda Wallace, 40, and Alexis Nieves, 33, were all apprehended after arms and heads were found in Babylon park on Tuesday.

The four have each been charged with first-degree hindering prosecution, tampering with physical evidence by concealing or destroying, and concealment of a human corpse. 

It's unclear if police think any of the four are directly involved in the deaths of the victims - an unnamed 53 year-old man and 59 year-old woman from Yonkers.

Alexis Nieves, 33, leaves court in Suffolk County, Long Island, on Wednesday

Police sources told NBC New York that the brutal killings may have been linked to a love triangle, but further details have not been shared.

DailyMail.com visited the Amityville home shared by Brown, Mackey and Wallace Wednesday morning. 

Half-eaten food, an empty Tito's vodka bottle and an open carton of Minute Maid strawberry and pear juice was visible on a table inside the unkempt property.

It was raided Monday, with the food left unfinished inside suggesting residents had been taken by surprise.

The door of the home had also been broken down.

Nieves, of no fixed address, is believed to have been homeless. 

One neighbor who lives near the raided property says Wallace was a dog walker and that the house had visitors all hours of the night.

Three of the four suspects left court together on Wednesday

A broken door was visible at the Amityville property which was raided by police on Monday 

The neighbor, who gave his name as Josh, said: 'The only reason why I knew her name is because somebody pulled up yesterday and said "you know Amanda? She used to walk my dogs for me."' 

Josh said he'd previously witnessed Amanda walking her child to school.

Asked about worrying activity at the property prior to the raid, Josh said: '‘It’s hard to say. 

'The only thing that I noticed since I live just a few doors down is that there’s activity all throughout the night there. All the time. Just people pulling up staying there briefly. 

Josh added: ‘I have trouble sleeping in the morning so that’s why I know that at 4am there’s a car in front of the house.’

‘It’s horrifying. You know it goes on in the world but you don’t think it goes on in your own street.

‘It’s all shocking, it’s terrible.’

‘I don’t think I’m naïve, but who would expect something terrible like this.’
