Gilgo Beach Latest: Search Of Rex Heuermann's Home Wraps Up

MASSAPEQUA PARK, NY — The search for evidence at the home of the accused Gilgo Beach serial killer wrapped up Tuesday, Suffolk County District Attorney Ray Tierney said at a news conference.

The 12-day search, which started in Rex Heuermann's Massapequa Park home July 14, had continued into his backyard with a large excavator.

Tierney said that nothing has been concluded at this time from the "tremendous amount of information" found, and described the home as "cluttered."

"The list of items is quite large," he said, as investigators found multiple boxes.

He also said law enforcement found more than 200 guns in a "vault" like room in Heuermann's basement. The space was not hidden, he said, as there enough room for people to walk into it.

Over the weekend, investigators also used technology that could look through the ground in Heuermann's backyard.

The technology detected a "number of disturbances" that could only be seen once dug up, Tierney said. These "disturbances" can be anything that was buried into the ground, such as a cistern or rocks.

Law enforcement officers used excavating equipment for more than three hours Sunday, Newsday reported. Before that, police dogs reportedly scoured the property.

Nassau County police also warned the public to not visit the home, or else they will be issued summons.

So far, officials obtained a menagerie of items from the house including: a trove of more than 200 guns; a painting of a fair-skinned, blonde woman with large, deep-set, dark eyes, a gash on her right cheek; and a childlike doll enclosed in a display case.

Law enforcement also raided an Amityville storage unit last week, in attempts to obtain evidence. It has not been confirmed who the storage unit belongs to.

Tierney also said that he could not confirm if any human remains were found inside the home, as investigators searched for "trace evidence" or any type of evidence in sizes so small that it can be transferred or exchanged between two surfaces without being noticed.

Heuermann was charged July 14 with six counts of murder in the deaths of Amber Costello, Melissa Barthelemy, and Megan Waterman, whose remains were found in 2010 along Ocean Parkway.

Since 2010, at least 11 sets of remains have been found, believed to be related to the Gilgo Beach killings. Police have searched for a serial killer ever since. At least four of the killings included strangulation, and two showed signs of blunt-force trauma. The cause of death remains inconclusive for some victims.

Last week, Heuermann's DNA was entered into a statewide database to see if it matches any other unsolved crimes, according to a report.

Tierney said that his DNA was not put into a national database. Since Heuermann is not convicted, state law requires that only convicted felons' DNA are placed in national databases.

Law enforcement are also investigating any links between Heuermann and the deaths of four Atlantic City sex workers, found strangled to death in a drainage ditch behind an Egg Harbor Township motel in 2006, ABC Action News reported.

The identity of the killer of those four, known as the Eastbound Strangler, has been unknown for years.
