Gilgo Beach serial killer suspects Rex Heuermann’s $800,000 real estate portfolio in Las Vegas, South Carolina and Long Island

Gilgo Beach serial killer suspect Rex Heuermann owns a multi-state real estate portfolio worth about $800,000 — including the small but expensive Long Island home that police keep raiding.

The alleged killer, 59, is accused of slaughtering four sex workers in 2009 and 2010 before taunting one of their families with a burner phone.

Heuermann, an architect, was arrested Thursday night outside his Midtown Manhattan office.

DailyMail.com can confirm that the married Heuermann bought his share of the Nevada two-bedroom, two-bath condo for $16,955 in 2005 with his wife, Asa Ellerup, years earlier, before one of the murders happened, in 2005.

He also owns a $154,000 piece of land in Chester, South Carolina where he planned to retire near his brother Craig.

It is unclear if it is the city where police found the Chevrolet Avalanche seized in South Carolina as part of the murder investigation.

Neighbors there told Fox News that Heuermann’s brother, Craig, often spoke about him and his plans to buy more real estate in the area.

“He told me when I first moved here that his brother owns that lot across the road, and his brother is going to retire here, and when he does, everyone will leave,” the neighbor said.

His plan was to “buy everything up,” the neighbor added. Chester is a small rural town about 50 miles southwest of Charlotte.

The Vegas condo is located in a lavish complex with a resort style pool, spa, tennis court, putting green and fitness facilities.

Police have yet to confirm whether they are investigating other areas to see if Heuermann committed any further violations in the US.

But court documents say the three murders he’s charged with took place while his wife was away from their home in New York, visiting relatives in Iceland.

It’s not clear when Heuermann or his wife last stayed at the resort, which also offers shuttle service to the strip and back.

Club de Soleil could not confirm whether Heuermann and his wife still owned a timeshare at the resort, but confirmed that their names were in the system.

They declined to comment further when DailyMail.com contacted them and advised that further questions be directed to the police.

Other details about the alleged killer’s finances show that he owed thousands in taxes to the IRS.

Nassau County records show that Heuermann once owed $425,000 in taxes, dating back to 2005, about half of which has been repaid or is no longer due.

Heuermann and his wife also owe $81,500 in income taxes to the state, according to documents.

The architect has also filed several lawsuits in New York, accusing drivers of injuring him in collisions.

Three of those cases have been settled or discontinued, and one is still pending, according to court documents.

Heuermann, a father of two who ran RH Consultants & Associates, has denied killing Gilgo Beach victims Melissa Barthelemy, Megan Waterman and Amber Costello.

Police say they expect to charge him with the murder of Maureen Brainard-Barnes and are not ruling out he may be responsible for further crimes.

Authorities had been tracking the alleged killer for at least a year before leaving his Midtown Manhattan office — and ended their investigation early for fear he might strike again.

They arrested him carrying a burner phone, with court documents revealing that he used a phone on each of his victims.

Suffolk County DA Ray Tierney said Friday Heuermann continued to patronize sex workers “at all hours of the night” and used fire phones to hide his identity.

Police are now searching two storage units in Amityville, next to Massapequa Park, where Heuermann lived all his life.

His house, where he has lived since the 1980s, is also being dismantled by forensic teams who have been painstakingly removing items from the property since Friday.

He was tracked down after a task force was set up in 2022, court documents showed he had searched for updates on the case more than 200 times over a 14-month period.

A witness saw a first-generation Chevy Avalanche parked in Amber Costello’s driveway, around the time she disappeared.

Heuermann also physically matched the witness’s description of a man Amber had been seen with.

Agents were able to track down the owner of the rare vehicle, which led them to Heuerman and the breakthrough in the case.

FBI investigators tracked down two areas of interest during their initial investigation in 2012, identifying where calls to Melissa Barthelemy’s family came from.

In January 2023, hair was found on a piece of burlap used to wrap one of the Gilgo Beach victims, matched with DNA found on a pizza box in Heuermann’s trash.

The Gilgo Beach investigation began in 2010 after sex worker Shannan Gilbert disappeared and a search for her body uncovered the remains of several other women.

Authorities made some shocking discoveries when the remains of eight women, a man and a child were found near Gilgo Beach between December 2010 and April 2011.

Some of the remains found also matched partial remains found decades earlier, as far back as 1996.

But in 2012, the case slowed when medical examiners ruled that Shannan Gilbert had accidentally drowned during a drug-induced panic.

Her family has filed a lawsuit against the investigating police, certain of her murder. An independent autopsy organized by the family also contradicted the earlier findings.

Four years later, in 2016, Suffolk Police Chief James Burke was jailed for assaulting a suspect who in 2012 stole his duffel bag that allegedly contained sex toys and porn tapes.

His boss, District Attorney Thomas Spota, was also jailed for obstruction of justice in connection with the scandal.

In a twist that year, a lawyer for victim Shannan Gilbert’s family said Burke should be investigated, and brought forward a sex worker who claimed she had an aggressive encounter with him in 2011.

Suffolk Police Commissioner Rodney Harrison has dismissed speculation linking him to the case.
