Gilgo Beach suspect Rex Heuermann reads about his case in newspapers and refuses visit requests from true-crime fans

• Gilgo Beach suspect Rex Heuermann has been in jail since July on charges of killing three women.
• The New York Times reported Heuermann receives visit requests from true-crime fans and journalists.

The man suspected of killing at least four women whose remains were later found buried on a Long Island beach has spent much of his time behind bars reading about his case and refusing visit requests from journalists and true-crime fans, according to the Suffolk County sheriff.

Rex Heuermann, 59, has been in the Suffolk County jail since July. He is charged with the murders of three women who went missing in 2009 and 2010 and has pleaded not guilty to all counts.

Sheriff Errol Toulon gave The New York Times insight into Heuermann's daily routine in jail. Toulon said Heuermann is often brought to a secluded section of the exercise yard for an hour at a time, where he walks laps alone. The Times also reported that Heuermann reads books from the jail's library and watches a TV controlled by jail guards outside his cell.

According to the Times, Heuermann has not received any visits from his wife and children.

Authorities are far from finished with their investigation into the Gilgo Beach homicides — in total, 11 victims' remains have been found at or near the Gilgo Beach area. Just in August, investigators identified one of the victims as Karen Vergata, who disappeared in 1996, though authorities have not said whether Heuermann is suspected in her death.

The Times reported that investigators have been interviewing female jail inmates in Long Island who have previously worked as escorts. All three Gilgo Beach victims Heuermann has been charged with killing were escorts, and authorities suspect that Heuermann may have frequented many sex workers in Suffolk County.

The county's district attorney, Ray Tierney, even said during a July press conference that authorities moved quickly to arrest Heuermann once they realized he was seeing escorts and potentially endangering them.

"We learned the defendant was using these alternate identities and alternate instruments to continue to patronize sex workers, which, of course, made us very nervous," Tierney said.

In the months since Heuermann's arrest, jail officials have interviewed about 120 female inmates so far — 10 of whom have said they encountered Heuermann in various ways, the Times reported. According to the newspaper, some received online date requests from Heuermann, and others met up with him in person.

Toulon told the Times that two of those 10 women reported having frightening intimate encounters with Heuermann, though neither were injured.

Heuermann's defense attorney did not immediately respond to a request for comment from Insider.
