Wife of Gilgo Beach 'serial killer' WAS in town on the night of at least one of the murders, attorney claims - despite her insistence she knew nothing about sex worker deaths

Rex Heuermann, 60, was charged with murder of four sex workers whose bodies were among 11 found on coastline close in Long Island between 2010 and 2011His estranged wife Asa Ellerup was out of town during each of the three murders, according to Suffolk County District Attorney Ray TierneyBut attorney John Ray, who represents families of two victims, cast doubt about whether she was around, during a university event in Queens on Tuesday night

An attorney for the families of two Gilgo Beach victims has questioned whether the wife of accused serial killer Rex Heuermann was actually in town longer than prosecutors believe.

Heuermann, 60, was charged with the murder of four sex workers whose bodies were among 11 found on the desolate stretch of coastline close to their Long Island Home between 2010 and 2011.

His estranged wife Asa Ellerup was out of town during each of the three murders, according to Suffolk County District Attorney Ray Tierney, and has not been accused of any wrongdoing.

But attorney John Ray, who represents the families of Shannan Gilbert and Jessica Taylor, has cast doubt about whether she was around, during a St. John’s University event in Queens on Tuesday night.

He questioned whether she was in town and claimed she may have been around during one of the murders.

Heuermann, 60, was charged with murder of four sex workers whose bodies were among 11 found on the stretch of coastline close to their Long Island Home between 2010 and 2011

The first victim, 24-year-old Melissa Barthelemy, was discovered by Suffolk County Police on December 11, 2010. The body of Megan Waterman, 22, from Maine, was found two days later

Heuermann is also charged with killing Amber Costello (left) and Maureen Brainard-Barnes (right)

Ray has claimed he spoke to a hotel manager in Atlantic City who told him that Ellerup and her two children arrived there later than investigators think.

If true, this would mean they would have been in town during at least one of the murders.

But attorney Bob Macedonio, who represents Ellerup, denied these claims and said if District Attorney Tierney was wrong, the entire case against Heuermann would collapse.

‘When, in the course of any investigations on any criminal matters, do they do that up front in a bail application?,’ he told Fox News.

‘Very, very rarely. … If he’s wrong, it creates reasonable doubt in his whole case.’

While former federal prosecutor Neama Rahmani, who is not involved in the case, said: ‘The DA’s statement would be a potential problem if it were wrong.

‘But why would the DA argue something they were unsure of?’

Heuermann is currently being held at a Suffolk County prison in connection to four murders.

In July, he was charged with killing Melissa Barthelemy, Megan Waterman and Amber Lynn Costello, who disappeared in 2009 and 2010.

Authorities later charged him with the murder of fourth victim Maureen Brainard-Barnes in January.

Cops have released a laundry list of ‘red flags’ that they say led them to Heuermann as a suspect, with the first piece of evidence being a Chevrolet Avalanche owned by him that was linked to the murder of Costello by a witness.

According to documents filed in Suffolk County court, investigators were then able to link that car to Heuermann’s cellphone records, which tied him to locations related to the murders, which eventually led them to obtain a DNA sample.

Police say that Heuermann used Melissa Barthelemy’s phone to make taunting phone calls to her family from the victim’s phone, calls that were made steps from his Manhattan office.

Following the identification of Heuermann as the owner of the Chevrolet, cops issued over 300 subpoenas, search warrants and other legal processes to obtain further evidence.

Ellerup arrived in court in November to hear the evidence presented as her estranged husband faces murder charges over the deaths of four sex workers

Ellerup visited the Manhattan architect in jail for the first time in November, and has been seen attending court to ‘see for herself what is presented in court.’

In August, she was previously accused by attorney Ray of being involved in the grisly killings.

Police have not indicated any link involving Ellerup or the couple’s children with the murders, however Ray claims to have witnesses who he says can confirm her presence when Heuermann would bring home sex workers.

He said that her alleged presence when he would do so suggests she may have had knowledge of the killings, a claim refused by Macedonio who said his client and her children are not under any suspicion by investigators.

Macedonio said Ellerup was not in the region at the time her husband was allegedly carrying out the killings.
