The New York prosecutor handling the Long Island serial killer case is visiting the suspect's house Tuesday, where police have been executing search warrants for more than a week.

Suffolk County District Attorney Ray Tierney's office said the prosecutor would speak with the media outside the Massapequa Park home of Gilgo Beach suspect Rex Heuermann around 12:30 in Nassau County.

Police arrested Heuermann near his Manhattan office on July 14 on a half-dozen murder charges in connection with three of the four Gilgo deaths – Melissa Barthelemy, 24, Megan Waterman, 22, and Amber Costello, 27.

At the time, they said he remained the prime suspect in the death of Maureen Brainard-Barnes, 25, whose remains they found near the other three.

He pleaded not guilty the following day at his arraignment.

When Tierney and Suffolk Police Commissioner Rodney Harrison both took office in early 2022, they announced a new task force to crack the unsolved Gilgo Beach murders.

The so-called Gilgo Four victims' remains were among a shocking 11 sets of human remains discovered as part of a search for Shannan Gilbert, who placed a harrowing 911 call and then vanished into the marsh.

Police have since said that they believe Gilbert's death is not connected to the others and may have been accidental.

The new task force quickly zeroed in on Heuermann after they linked data from his phone, numerous burner phones and the victims' phones to the suspect vehicle and cell towers near his home on Long Island and office in New York City.

They first found his name in March of last year, just six weeks into the new investigation, and plucked him off the street in Manhattan earlier this month after building their cases and amid concerns he could strike again.

Heuermann's wife, Asa Ellerup, retained a high-powered Long Island defense lawyer and filed for divorce less than a week after learning of the charges against her husband.

Police in other states, including Nevada, South Carolina and New Jersey, are looking into Heuermann for possible connections to unsolved cases in those places.

He is due back in court Aug. 1 and faces up to life imprisonment without the possibility of parole if convicted.
