‘BTK Killer’ Dennis Rader calls Gilgo Beach suspect Rex Heuermann ‘a clone of me’

Notorious “BTK Killer’’ Dennis Rader says Gilgo Beach serial slay suspect Rex Heuermann is “a clone of me’’ — with a nearly identical personal profile and technology-fueled “downfall.

“I was arrested at age 59. Married, two kids. Husband, dad longtime a serial killer, stalker, used electronic devices, lives in a neighborhood undetected,’’ Rader wrote in a letter to Fox News, ticking off the litany of similarities between himself and Heuermann, who is from Massapequa Park, Long Island.

Rader — who is serving a life sentence for killing 10 people in Kansas — said that, as with Heuermann, advancements in science and technology ultimately led to his arrest.

“Heuermann was taken down [by] DNA and electronics, his downfall much like me,” wrote Rader, whose self-proclaimed nickname stems from his preference to “Bind, Torture and Kill” his victims.

The sadistic murderer claims he predicted the similarities between himself and the accused Gilgo Beach killer when the string of Long Island murders was a cold case years ago, declaring, “I was correct.”

Rader — a former Cub Scout leader and Christ Lutheran Church higher-up — was arrested Feb. 25, 2005, decades after slaughtering victims in the Wichita and Park City areas between 1974 and 1991.

Law enforcement matched DNA from one of Rader’s relatives to semen left at the scene of a quadruple homicide in 1974.

Rader’s bust came after he sent taunting letters to media outlets describing the gruesome details of the murders decades after committing them.

Heuermann, a 59-year-old architect and married father of two, was charged last week with three of the “Gilgo Four” murders of women on Long Island: Melissa Barthelemy, Megan Waterman and Amber Lynn Costello. He is the main suspect in the fourth victim, Maureen Brainard-Barnes, who disappeared in 2007, authorities have said.

He was busted last week after law enforcement linked data from his phone to victims’ phones and matched DNA from a discarded pizza crust to genetic material found on the body of a victim.

The arrest reportedly gobsmacked Heuermann’s wife, Asa Ellerup —  much like Rader’s family, FOX reported.

“My first question when a long sought suspect in multiple murders is caught is, ‘Does he have a family?’ ” said Rader’s daughter, Kerri Rawson, to Fox.

 “My family’s life was upended 18 years ago, February 2005, when we got the noon day knock and simple notification from the FBI, ‘Your father is BTK.’ “
