Rex Heuermann Got Scammed: How Amber Costello Broke Gilgo Beach Open

Rex Heuermann got hustled on September 1, 2010 — and it may be the reason he's in prison. Amber Costello's roommate Dave Schaller ran a scam on a client at their West Babylon house. The client — described by Schaller as massive, an "ogre" — left, got into a first-generation Chevrolet Avalanche, and sent a text: "That was not nice, so do I get credit for next time." The next night, the same burner phone contacted Amber. She walked out to meet the man. Schaller saw the truck again. Amber never came back.

Episode 7 of "The Seven" — the final installment. That Avalanche description sat in the case file until 2022, when the Gilgo Beach task force ran it through vehicle registration records. The name that came back: Rex Heuermann, architect, Massapequa Park. From there — surveillance, the pizza crust, the DNA match, the warrants, the house searches, the planning document, the arrest.

Cell tower data tracked the burner phone from Massapequa Park to West Babylon on both nights. Amber was 27, four feet eleven, battling addiction. Her sister said she forgives Heuermann. The evidence trail that started with a roommate's description of a truck and ended with an arrest — all covered here. The last known victim became the case that broke everything open.
