Two of the four people arrested in connection with the human remains found scattered across Long Island appeared in court this morning.

Alexis Nieves and Jeffrey Mackey pleaded not guilty to concealment of a human corpse, among other charges. The court ordered that GPS monitors remain on both suspects until their next court date. They were released earlier this week with no bail.

Mackey’s attorney John Halverson says Mackey and Nieves are in a relationship and homeless because of the police investigation at the Amityville home. Both waived their right to speedy trial.

Halverson tells News 12 that his understanding is an indictment in the case could be coming. When asked, Halverson said he imagines prosecutors are looking to upgrade charges for Mackey and Nieves.

Nieves and Mackey are accused of hacking and scattering limbs in Babylon, West Babylon and Bethpage State Park.

According to the district attorney's office, GPS monitoring is a custodial condition under New York state law. That means unless the suspects are indicted or the order is extended, the monitors could come off.

Both suspects are due back in court on March 19.

The other two suspects, Steven Brown and Amanda Wallace, are due back in court on Monday.
