In a chilling revelation that has captured the attention of true crime enthusiasts nationwide, admitted Gilgo Beach serial killer Rex Heuermann has reportedly been exchanging correspondence with another notorious serial killer while awaiting sentencing in a New York correctional facility. According to Suffolk County Sheriff Errol Toulon, the former architect has developed a disturbing reading habit centered on true crime literature and has even responded to letters from one of America’s most infamous convicted killers.
Behind Bars: Inside Heuermann’s Daily Life at Riverhead Correctional Facility
Since his arrest in 2023, Rex Heuermann has been housed at the Riverhead Correctional Facility on Long Island, where he occupies a cramped 6-by-9-foot cell. Despite the grim circumstances of his confinement, Toulon revealed that Heuermann has maintained an unusually composed demeanor throughout his nearly three years in custody. The sheriff, who brings more than four decades of law enforcement experience to his observations, confessed that he has never encountered an inmate quite like Heuermann.
“No change of emotion, no change in facial expressions,” Toulon told ABC News. “I really think he’s a sociopath.” This clinical assessment aligns with what prosecutors described during the lengthy investigation into the Gilgo Beach murders, a case that stunned the nation and exposed a pattern of predation that stretched across more than a decade and a half.
A Limited Circle of Visitors
While most inmates typically receive visits from a wide network of friends and family members, Heuermann’s visitation list has remained remarkably narrow. According to Toulon, his only regular visitors have included:
- His daughter
- His ex-wife
- His attorney
- His therapist
This isolated social circle has done little to diminish Heuermann’s reputation for emotional flatness. The stoicism that defined his public persona during court appearances appears to have followed him into incarceration, raising troubling questions about the depth of his remorse and the psychological profile of a man who confessed to murdering eight women.
A Dark Reading List: True Crime Fuels Heuermann’s Downtime
To occupy the countless hours in his cell, Heuermann has developed what can only be described as a deeply unsettling literary preference. Sheriff Toulon shared that the convicted killer has been an avid consumer of true crime literature, working his way through books and periodicals that center on serial murder investigations.
Notable Titles on Heuermann’s Bookshelf
The reading material that Heuermann has consumed during his incarceration reads like a bibliography of the crime fiction genre:
- “Chosen to Die” by Lisa Jackson , A thriller following detectives pursuing a serial killer operating in Montana
- “Portrait in Death” by Nora Roberts , A novel featuring a homicide lieutenant tracking down a serial murderer
- “The Dead Girl” by Melanie Thernstrom , A memoir exploring the profound impact of murder on victims’ families
The choice of reading material has not gone unnoticed by law enforcement. While some might view his interest in crime-related content as merely a morbid curiosity, others see it as a window into a psyche that continues to be fascinated by the very acts he admitted to committing.
Correspondence With the Happy Face Killer
Perhaps the most shocking disclosure to emerge from Sheriff Toulon’s account is the revelation that Heuermann has been in communication with Keith Hunter Jesperson, the convicted serial killer infamously known as the Happy Face Killer. Jesperson gained his chilling nickname from the smiley face drawings he included on letters and postcards he sent to newspapers and authorities during his 1990s killing spree across multiple states.
According to Toulon, Jesperson “reached out a few times” to Heuermann, and the Gilgo Beach killer responded with at least one letter of his own. The specific contents of their correspondence remain unknown to the public, but the mere fact that these two admitted serial killers have been exchanging mail has prompted serious discussion about inmate monitoring protocols and the psychological risks of allowing such communication.
Who Is Keith Hunter Jesperson?
Jesperson was convicted of murdering eight women between 1990 and 1995, primarily targeting truck stop prostitutes along interstate highways. He later confessed to additional murders and was eventually linked to the deaths of women in states including Washington, Oregon, and Wyoming. His taunting correspondence with media outlets , featuring his signature happy face symbol , made him one of the most psychologically distinctive serial killers of his era.
The connection between Jesperson and Heuermann is particularly notable given that both men admitted to killing eight victims. Whether this numerical coincidence played any role in Jesperson’s decision to reach out remains unclear, but the parallel is impossible to ignore.
The Gilgo Beach Murders: A Recap of Heuermann’s Crimes
Rex Heuermann’s guilty plea in April of this year brought a measure of closure to one of the most haunting cold cases in recent American history. The Long Island serial killer case, often referred to as the Gilgo Beach murders, involved the discovery of multiple sets of human remains along Ocean Parkway near Gilgo Beach in 2010 and 2011. The initial discovery during the search for missing escort Megan Waterman led investigators to uncover additional bodies, eventually revealing a pattern of horrific violence that had gone undetected for years.
Heuermann’s Eight Confirmed Victims
Through his courtroom confession, Heuermann admitted to killing the following eight women:
- Melissa Barthelemy
- Megan Waterman
- Maureen Brainard-Barnes
- Amber Lynn Costello
- Jessica Taylor
- Valerie Mack
- Sandra Costilla
- Karen Vergata (though Heuermann was not formally charged in her death)
Prosecutors alleged that Heuermann specifically targeted sex workers and disposed of their remains in the remote stretches of beach and marshland along Long Island’s South Shore. The crimes spanned a 17-year period, suggesting a sustained campaign of predation that managed to evade detection despite occurring in one of the most heavily populated regions of the United States.
The Pending FBI Interview and Upcoming Sentencing
As part of his plea agreement, Heuermann was required to submit to an interview with the FBI’s Behavioral Analysis Unit, the division of the bureau that specializes in understanding criminal behavior and assisting with ongoing investigations. According to Sheriff Toulon, this interview has not yet taken place, though it remains a condition of his plea deal.
The Behavioral Analysis Unit interview is significant for several reasons. Profilers and investigators likely hope to glean additional information about:
- Any accomplices who may have assisted Heuermann
- The locations of any additional victims or remains
- The full scope of his criminal activities
- Any insights that could help resolve other unsolved cases
Heuermann is scheduled to be sentenced on June 17, where he is expected to receive a life prison sentence. Given the nature of his guilty plea to multiple counts of murder, it is virtually certain that he will spend the remainder of his days behind bars, with no possibility of parole.
What This Reveals About Inmate Psychology
The disclosures about Heuermann’s jailhouse behavior and reading habits offer a rare window into the mind of a convicted serial killer during the period between conviction and sentencing. His preference for true crime literature featuring detective protagonists who hunt serial killers raises uncomfortable questions about whether he views his own crimes through a lens of detachment and intellectual fascination rather than remorse.
The willingness of another serial killer to initiate contact with Heuermann also underscores a phenomenon that criminal psychologists have long observed: serial killers often develop a kind of dark community with one another, sharing interests, viewpoints, and sometimes even methodologies across prison walls. This underground network of correspondence can be both a source of study for law enforcement and a concerning breeding ground for continued criminal ideation.
As the June 17 sentencing date approaches, the public will be watching to see whether Heuermann’s demeanor remains as inscrutable as Sheriff Toulon has described. For a man who has admitted to ending the lives of eight women and who now passes his time reading about serial murder and corresponding with fellow killers, the courtroom may offer one final glimpse into the mind of one of America’s most chilling confessed murderers.
The case of Rex Heuermann remains a haunting reminder of how long-term serial predation can flourish undetected, and his ongoing behavior behind bars continues to raise important questions about criminal psychology, inmate management, and the pursuit of justice for victims and their families.
