Long Island police reveal how Rex Heuermann’s family reacted to his arrest for Gilgo Beach murders

‘They were disgusted. They were embarrassed,’ Suffolk County Police Commisioner told CNN about Mr Huermann’s family

The family of Gilgo Beach murder suspect Rex Heuermann was disgusted and shocked to learn about the damning evidence linking him to at least three murders, according to law enforcement.

Mr Heuermann’s bombshell arrest last sent shockwaves across the shoreline community of Gilgo Beach in Long Island following 13 years of unanswered questions over a trail of bodies found in the area. The married father-of-two is facing six charges over the murders of Amber Castello, Megan Waterman and Melissa Barthelemy — all sex workers in their 20s whose bodies were found during a missing persons investigation in 2010.

He is also the prime suspect in the murder of a fourth woman, Maureen Brainard- Barnes, with authorities saying more charges are expected. The Suffolk County Police Department is also probing potential ties to the other six bodies linked to the Gilgo Beach case, as well as other murders nationwide.

Police Commissioner Rodney Harrison told CNN that Mr Heuermann’s family reacted with shock to his arrest and are now cooperating with the investigation. Before being taken into custody, Mr Heuermann, 59, had outwardly led a normal life, working as an architect in Midtown Manhattan and making very little impression on his neighbours in Massapequa Park.

“They were disgusted. They were embarrassed,” Mr Harrison said. “So, if you ask me, I don’t believe they knew about this double life that Heuermann was living.”

Mr Heuermann lived in Massapequa Park with his wife of more than 25 years. His attorney said in a statement last week that Mr Heuermann is nothing but a “loving husband” and “devoted father and suggested that the Suffolk County task force leading the investigation is ignoring “stronger leads.”

“Rex Heuermann is 59 years old with no prior criminal history,” criminal defence lawyer Michael Brown said in a statement to News 12 Long Island. “He is a loving husband to his wife .. and an involved and dedicated father to his daughter and stepson.

“There is nothing about Mr Heuermann that would suggest that he is involved in these incidents.

“And while the government has decided to focus on him despite more significant and stronger leads, we are looking forward to defending him in a court of law before a fair and impartial jury of his peers.”

The task force investigating the murders linked Mr Heuermann to the case through cellphone evidence, witness testimony, chilling searches found on his electronic devices and DNA found in one of the crime scenes.

More forensic analysis revealed that female hairs found in the three crime scene locations belonged to Mr Heuermann’s wife. However, authorities have determined through cellphone records that Mr Heuermann’s wife was out of state when the murders took place.

At the time Barthelemy went missing in July 2009, Mr Heuermann’s wife was in Iceland. She visited Maryland around the time Waterman disappeared in June 2010, and also travelled to New Jersey when Costello was last seen in September of that year.

Records also show that several online accounts under fictitious names linked to Mr Heuermann were used for illegal activities. Mr Heuermann allegedly used those accounts and burner phones to contact women for prostitution services, as well as making chilling online searches.

The searches included sadistic, torture-related pornography, child pornography and disturbing content. Mr Heuermann is also accused of searching “why could law enforcement not trace the calls made by the long island serial killer,” “why hasn’t the long island serial killer been caught” and “new phone technology may be key to break in case.”

Former NYPD Chief of Detectives Robert Boyce told ABC’s Good Morning America on Tuesday that the 59-year-old suspect is now being looked at in connection to missing persons cases and murders far beyond the shores of Long Island – across the tri-state area of New York, New Jersey and Connecticut and even nationwide.

“I made some phone calls yesterday to see what they were doing. They’re looking at all missing persons who have never been found and see if they can put those together,” he said.

“Not just in Suffolk, but throughout the tri-state area to see what they can put together. There’s also the FBI looking at national issues as well.”

Mr Boyce pointed out that Mr Heuermann had been “free” for many years – as the accused killer continued his daily life for 13 years after the bodies were first discovered in 2010.

“So we’ll keep going in that respect becasue he was free for many years,” he said.

“He lived that Manhattan to Massapequa – that was his whole life right there – but it doesn’t mean he didn’t step out of it. So we have to look all the way around.”

An NYPD official told ABC News that the married father-of-two’s DNA has been entered into a statewide database and that his alleged MO is being compared to other cases across New York state – including those during the period he was allegedly active in Gilgo Beach.
