LONG ISLAND, NEW YORK: The lawyer of Rex Heuermann’s children, who are living in a “horror show” after their father’s arrest on July 13, for the Gilgo Beach murders, speaks out about their ordeal and legal rights.

Rex Heuermann, 59, an architect, was arrested near his Manhattan office and charged with killing three women whose bodies were found near Gilgo Beach in 2010. He is also the prime suspect in the death of a fourth woman who went missing in 2007.

How are Rex Heuermann’s children coping with his arrest?

He pleaded not guilty to all charges and appeared in court on August 1 where prosecutors said they have eight terabytes of evidence against him, as per News Nation. Police have not linked him to seven other bodies that were also discovered near Gilgo Beach between 2010 and 2011.

V Mbess Mitev, the attorney of Christopher Sheridan, 33, and Victoria Heuermann, 26, who lived with their parents in Massapequa Park home, told Fox News that the siblings are “constantly… having to reevaluate what is happening to them, almost in real-time.”

'They’re living in a surreal, waking horror show'

He said they are “trying to regain some basic sense of normalcy, which is completely impossible at this point. They’re living in a surreal, waking horror show.”

Mitev said that Christopher and Victoria are “bystanders who are caught up in this developing legal case of the century” and that they need legal representation because “their rights and liberties have to be protected.”

He said that the investigation is “now heating up with the DA handing over troves of documents last week,” and that his client’s interests may be affected by the direction of the probe.

Mitev also said that the condition of their house, which was searched and "damaged" by investigators from July 14 to July 25, is their “paramount concern.”

Lawyer says privacy has completely 'eroded under the harsh glare of the spotlight'

He said that their mother Asa Ellerup who filed for divorce from Heuermann on July 19 and hired attorney Robert Macedonio to represent her and Christopher, who has developmental disabilities, were “blindsided” by the charges against Heuermann.

Ellerup previously told The New York Post that her children “cry themselves to sleep at night.”

The lawyer further said that Christopher and Victoria ask that their “privacy, which is completely eroded under the harsh glare of the spotlight” be “maintained and to whatever minimum degree it can be at this point.”

He said that they are hoping for a swift resolution of the case and justice for the victims. The next court date for Heuermann is September 27.
