LONG Island Serial Killer suspect Rex Heuermann’s wife was home during visits from other sexual partners, a witness has claimed.

Heuermann was arrested in July in connection to the deaths of three women whose remains were discovered along Gilgo Beach.

Heuermann has since pleaded not guilty to three counts of first-degree murder and three counts of second-degree murder.

Attorney John Ray, who is representing victims in the case, appeared with Suffolk County Police Commissioner Rodney Harrison on Wednesday to present new evidence – including two affidavits seen by The U.S. Sun – relating to two other victims, Shannan Gilbert and Karen Vergata.

Heuermann has not faced charges in connection to those two women.

His wife Asa has also consistently and vehemently denied having any knowledge of the crimes that Heuermann has been charged with.

Ray shared the stories of four new witnesses who have come forward in the case, two of whom have given official sworn statements.

“We are not done with this investigation,” Harrison said.

“We have the information, we’re working it, and we’ll see where it leads up down the road.

“We have a job here as law enforcement, as the Suffolk County Police Department, to make sure we investigate every single complaint or interest in this case,” Harrison continued.

He said that officials will “make sure that we look under every single stone to see if there is any connection to Rex Heuermann, or if there is a connection to somebody else that may be involved with the bodies that were discovered on Ocean Parkway.”

The U.S. Sun has reached out to the Suffolk County Police Department and the Suffolk County District Attorney for further comment.

‘HUNGRY AND HOMELESS’

One witness who came forward – who self-described as a “former swinger” – claims she encountered Heuermann and his wife, Asa Ellerup, in the 1990s, an affidavit obtained by The U.S. Sun revealed.

In the sworn affidavit, the unnamed witness wanted the “truth to be known about Rex Heuermann and others, including his wife Asa.”

The witness claimed that while paying a visit to a club in Manhattan known as Le Trapeze, she saw information posted to a wall there advertising a home in Massapequa Park.

Either Heuermann or Asa had posted their contact information, the affidavit stated.

The witness and the man she was with at the time, referred to as RW in the affidavit, chose to go to the Heuermann home and picked up a woman believed to be Vergata along the way.

Vergata was described in the affidavit as being “hungry and homeless.”

“When we stopped for gas, she said that she was scared,” the affidavit stated.

“I told her not to be scared because RW was a cop, she couldn’t be safer than being with a cop.”

‘AFRAID OF REX’

Once they arrived at the Massapequa Park home, the witness said that Vergata went downstairs.

She also shared that Heuermann and her boyfriend disappeared for a while and she stayed upstairs with Asa.

Heuermann’s wife shared that “Rex brought her from her country, and that everything she had, he has given to her,” the witness continued.

“She said that she was lucky that he was rich. She said she was also afraid of Rex.”

The witness went on to state that she asked Heuermann’s wife if she wanted to have sex.

But Asa “didn’t wish that,” the witness continued.

‘PLAYING A GAME’

As the witness and RW were preparing to leave Heuermann’s home, they allegedly saw Vergata’s face in a window inside.

“She looked scared. I had a sense that she was calling for help,” the affidavit stated.

Vergata “suddenly ran outside, naked, and ran about by the garage,” the affidavit continued.

“RW told me not to worry about her, that she was OK, they were only playing a game.

“We left without her. I felt uneasy that we left without the woman.”

The witness continued to share that she only came forward after seeing Heuermann’s face on the news, along with Vergata’s.

“I was shocked, and deeply sorrowful for having left her behind at Heuermann’s house,” the witness said of Vergata.

While Asa is named in the affidavit, the witness has not alleged that the wife had any knowledge of the crimes with which Heuermann has been charged.

INVESTIGATION DEEPENS

The update from Ray and Harrison came just days after it was revealed that two more investigators were added to the task force assigned to the case.

Those two investigators have been tapped to look further into the deaths of Vergata and Valerie Mack.

Mack, who used the alias Melissa Taylor, went missing from her New Jersey home in 2000.

Her family didn’t report her as a missing person.

Her dismembered corpse was found in two different Long Island locations; first in September 2000 and later on April 4, 2011, near Gilgo Beach.

Heuermann is being held at Suffolk County Jail without bail.

He is due back in court on November 15.
