One year after the arrest of Gilgo Beach serial killer suspect Rex Heuermann, authorities say they are still searching through evidence seized from his Massapequa Park suburb home during a 12-day search.
On July 13, 2023, Heuermann, now 60, was arrested outside his Manhattan office in connection with the 2010 deaths of Melissa Barthelemy, 24; Megan Waterman, 22; and Amber Costello, 27, Front Page Detectives reported.
Since that time, authorities have also added additional charges in three additional murders. Heuermann was also charged with the killing of Maureen Brainard-Barnes, 25, whose remains were near the other three.
In June 2024, authorities filed charges against Heuermann for the alleged murders of Jessica Taylor in 2003 and Sandra Costilla in 1993, Front Page Detectives previously reported.
In addition, authorities say he is the prime suspect in at least one more murder, the killing of Valeria Mack, FOX News reported. Her remains were dismembered and scattered across the brush east of Gilgo Beach and the woods of Manorville.
He is also being examined in at least three other states where he had ties for potential connections to cold cases in those jurisdictions, officials said.
In a computer file obtained from his home, Heuerman allegedly wrote that “small is good,” since most of his suspected victims are notably petite.
Heuermann also allegedly kept a list of “problems,” “supplies,” targets and dump sites in this file.
He also seemed to read up on other serial killers and studied the work of John Douglas, a former FBI profiler who wrote the influential book “Mindhunter.”
Heuermann also allegedly had a running list of traffic cameras along the two highways between his house and the two known dump sites in Manorville and North Sea.

Four of his alleged victims were referred to as the Gilgo Four, whose remains were all found near one another just east of Gilgo Beach. Both Taylor and Castillo were dismembered, and police found parts of their remains near Gilgo Beach.
According to court documents, police have received reports from two witnesses in two separate murders regarding reports of seeing Heuermann’s old Chevy Avalanche. Police also reportedly have decades of phone records and internet searches, as well as his DNA.
