Long Island body parts found: What we know so far about the investigation

Four people were arrested Wednesday, arraigned and released without bail in connection to the dismembered body parts found last week on Long Island.

Two women and two men – identified as Steven Brown, 44, of Amityville, Jeffrey Mackey, 38, of Amityville, Amanda Wallace, 40, of Amityville, and Alexis Nieves, 33, who is homeless – were all charged with hindering prosecution, tampering with evidence and concealing a human corpse. All four were arraigned and released, Suffolk County District Attorney Raymond Tierney said in a statement.

Here's everything we know about the investigation, from the first remains discovered last week in Babylon and Bethpage, to the arrests of four people and what we know about the victims.

Who are the victims?

The brother and sister of the 53-year-old victim attended a March 11 court appearance. They said defendant Steven Brown is their cousin and their younger brother, Malcolm Craig Brown, was the male victim, FOX 5 NY's Jodi Goldberg reported.

Police also released the identity of the female victim: 59-year-old Donna R. Conneely.

Investigators said they shared an address in Yonkers.

"It is our understanding that the Suffolk County Police Department is still investigating these murders. Unfortunately, due to ‘Bail Reform’ passed by the New York State Legislature in 2019, charges relating to the mutilation and disposal of murdered corpses are no longer bail-eligible, meaning my prosecutors cannot ask for bail," Tierney's statement read.

According to officials, those charged were forced to surrender their passports and wear monitoring devices. They are unable to leave the country.

Search warrant executed in Amityville

Suffolk County officials said a search warrant was executed on Railroad Ave in Amityville on Monday, the same address listed for Brown, Mackey and Wallace.

Investigators found meat cleavers, butcher knives and blood in the apartment.
