Two people were indicted on murder charges in connection with the February killing and dismemberment of a former Yonkers couple living on Long Island, the Suffolk County District Attorney's Office announced Monday.

Mackey was charged with two counts and Nieves one count. The pair, along with two others ‒ Steven Brown, 44, and Amanda Wallace, 40 ‒ were arraigned Friday for roles in the alleged plot.

According to a news release from Suffolk County District Attorney Raymond Tierney, a Suffolk County Police Department investigation showed that Malcolm Brown and Conneely were allegedly stabbed at 25 Railroad Ave. in Amityville on Feb. 27. Police say Malcolm Brown was stabbed once in the neck and torso and Conneely was stabbed multiple times in the neck and back.

After the stabbings, Tierney said the defendants allegedly dismembered Brown and Conneely's bodies in a bathroom and left the remains in Southards Pond Park, Bethpage State Park and a wooded area in West Babylon. Some of Brown's body parts were found in Southards Pond Park on Feb. 29 by a local resident. Conneely's head and torso were later found by police not far from the first location.

Tierney said police recovered several cutting instruments including knives and meat cleavers at the Amityville residence, where all four defendants appeared to be staying at the time. Blood was also allegedly found in multiple locations throughout the residence.

Tierney said Malcolm Brown, who is Steven Brown's cousin, and his partner Conneely were familiar with all the defendants prior to the murder. Steven Brown and girlfriend Wallace were the primary residents of 25 Railroad Avenue. Mackey and Nieves were also living in the residence at the time.

The defendants were arrested on March 4 on charges of hindering prosecution, tampering with physical evidence and concealment of a human corpse. As the charges made them ineligible for bail, all four were released from jail but were required to wear GPS monitors.
