Rex Heuermann Part 4: THE ALLEGED HUNT — LISK's Burner Phones and Gilgo Four Victim Selection

Part 4 of 5: How prosecutors say the alleged Gilgo Beach Killer selected, contacted, and killed his victims along Long Island.

July 2009. Amanda Barthelemy, fifteen years old, received a call from her missing sister's phone. A man's voice asked: "Do you know what I did to your sister?"

Over the following weeks, the man called seven times. He described what he'd done. On August 26, he said: "You won't see her again. I killed her."

In this episode, we examine the alleged LISK hunting pattern that prosecutors say links Rex Heuermann to seven Long Island murders over three decades.

The Gilgo Four and other victims share characteristics. All were sex workers. All were petite—the planning document allegedly notes "small is good." All advertised on Craigslist. All were allegedly contacted via burner phones. All allegedly disappeared when the alleged Long Island Serial Killer's family was traveling.

According to court documents, investigators found no instance where Heuermann's personal phone was in a different location than burner phones used to contact the Gilgo Beach victims. The FBI traced calls to "the box"—a small area of Massapequa Park.

Heuermann's house was inside the box.

Suffolk County prosecutors also allege fake email accounts under names like John Springfield and Thomas Hawk—used to create profiles and contact sex workers. Even in 2022, investigators watched the alleged Gilgo Beach Killer add money to burner phones.

And the alleged taunting went beyond phone calls. Prosecutors say LISK searched obsessively for the Ocean Parkway investigation. For photos of victims. For photos of their families.

DA Tierney: "His intent was specifically to locate these victims, to hunt them down, to bring them under his control, and to kill them."

Rex Heuermann has pleaded not guilty. The Gilgo Beach trial is September 2026.
