NEW YORK—An intense police search of the Long Island home of Rex Heuermann is now complete, authorities said Tuesday as they ended a 12-day hunt for evidence that involved ripping up the yard and the discovery of a basement vault containing hundreds of weapons kept by the man accused of killing at least three women more than a decade ago.
At a press conference outside the Massapequa Park home where Mr. Heuermann lived with his wife and two kids, Suffolk County District Attorney Ray Tierney said police had found a “tremendous amount of information” during their search.
He declined to describe the bulk of the material, but said there was not a “singular piece of evidence” that jumped out to him.
The search turned up at least 279 weapons kept inside a thick basement vault large enough for a person to walk into, Mr. Tierney said. Police took boxes of additional evidence from the house, which he described as a “very cluttered environment.”
An effort in recent days to dig up the backyard in search of possible clues about where the murders were committed did not yield any “large items of evidence,” he added.
A coalition of law enforcement agencies have been pouring over the property since July 14, when Mr. Heuermann was arrested and charged with killing three women—Melissa Barthelemy, Amber Costello, and Megan Waterman—and dumping their bodies along a remote stretch of coastal highway near Long Island’s Gilgo Beach more than a decade ago. Prosecutors identified him as the prime suspect in the death of a fourth woman, Maureen Brainard-Barnes.
Mr. Heuermann, who worked as an architect in Manhattan, has denied the charges through his lawyer.
The killings, all of which involved women engaged in sex work, happened while Mr. Heuermann’s family members were out of town, according to court papers. There is no indication his wife or children had knowledge of the crimes, Mr. Tierney said.
During the search, police used a scanning technology to identify “disturbances” in the ground outside Mr. Heuermann’s property, Mr. Tierney said. An excavator dug up the yard, and investigators with shovels could be seen scraping through freshly upturned earth.
“There was nothing of note taken from the back yard,” he said. “As far as remains, there is a whole entire trace analysis we have to go through with the house with regard to hair fibers, DNA, blood, which we’ll have to await the results of.”
Police were also seen pulling a large doll encased in glass and a portrait of a woman with a bruise on her face from the house. Mr. Tierney said it would be “quite some time” before all of the evidence could be tested for forensics.
The end of the search comes as police in Las Vegas and South Carolina are beginning their own investigations into whether the suspect may have been connected to any unresolved cases. Mr. Heuermann owns a timeshare in Las Vegas and planned to retire in a remote area of South Carolina, where his brother currently lives.
Mr. Tierney declined to discuss specifics in the other cases on Tuesday, but noted the investigation “is not limited to New York state.”
Mr. Heuermann is due back in court on August 1st.
