Suffolk County investigators spent 18 months painstakingly building a case against suspect Gilgo Beach serial killer Rex Heuermann – the married dad of two who allegedly left a trail of damning evidence behind linking him to the so-called “Gilgo Four” slayings.
A witness reported seeing a first-generation Chevrolet Avalanche pull up to slay victim Amber Costello’s West Babylon, Long Island home around the time she was last seen on Sept. 2, 2010.
The same type of pickup truck, down to the make and early model, was later determined to be registered to Heuermann – and a similar-looking vehicle was seen getting towed from the architect’s Massapequa home on Friday.
