RIVERHEAD, Long Island (PIX11) – Two suspects accused of hiding human remains across Long Island have been charged with murder, according to officials.
Jeffrey Mackey and Alexis Nieves both pleaded not guilty to the charges in the deaths of Malcolm Brown and Donna Conneely, officials said. Steven Brown and Amanda Wallace were also arrested in connection to the case back in March.
Mackey was charged in connection to Malcolm Brown and Conneely's death, while Nieves was charged in Conneely's death.
Mackey is accused of repeatedly stabbing Malcolm Brown to death before attacking Conneely, who was trying to intervene, prosecutors said. Conneely was then stabbed in the neck and strangled by Mackey before Nieves allegedly beat and stabbed her, according to prosecutors.
The knife used to kill both Malcolm Brown and Conneely was allegedly used to rob a gas station, according to prosecutors.
The victims' body parts were later discovered in three locations, prosecutors said. Human remains were originally discovered in Southards Pond Park in Babylon on Feb. 29, before more body parts were discovered in a wooded area in West Babylon and Bethpage State Park on March 5.
Steven Brown and Malcolm Brown are cousins.
Mackey and Nieves are also facing charges of concealment of a human corpse by “hacking,” hindering prosecution and tampering with physical evidence, along with Steven Brown and Wallace. Less than an hour after being charged, they were all released without bail.
Their release has sparked outrage among officials who blamed New York’s bail reform laws. Wallace was arrested again after her release for alleged shoplifting from a CVS store, prosecutors said.
Mackey faces up to two terms of 25 years to life in prison while Nieves faces one term of 25 years to life in prison.
