The Long Island Serial Killer's Alleged Hunt: LISK's Burner Phones, Taunting, and Gilgo Four Pattern

July 2009. A fifteen-year-old girl answers her missing sister's phone. A man's voice asks: "Do you know what I did to your sister?"Amanda Barthelemy received seven calls over the following weeks. The man described what he'd done. On August 26, he said: "You won't see her again. I killed her."In Part 4 of our Gilgo Beach Killer series, we examine the alleged LISK hunting methodology—how prosecutors say the Long Island Serial Killer selected vulnerable women, contacted them via burner phones, and allegedly taunted families after the killings.The seven victims share a pattern. All sex workers. All petite—the planning document notes "small is good." All allegedly contacted via burner phones. All allegedly disappeared when the alleged Gilgo Beach Killer's family was away.According to court documents, investigators found no instance where Heuermann's personal phone was separate from burner phones when they were active. In 2012, 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: John Springfield, Thomas Hawk, Andrew Roberts. Used to create dating profiles and contact women. Under one alias, "thousands of searches" were allegedly conducted for violent pornography and worse.Even in 2022, investigators watched the alleged Long Island Serial Killer add money to burner phones. The alleged methodology never stopped.DA Ray Tierney: "His intent was specifically to locate these victims, to hunt them down, to bring them under his control, and to kill them."Hunt. The word appears in the planning document prosecutors allege was found on LISK's hard drive. "Get sleep before hunt."Rex Heuermann has pleaded not guilty. The Gilgo Beach trial is September 2026.
