Who is Rex Heuermann?
The accused grew up in Nassau County after his birth in 1963. He stated in a past interview that he had worked in the city since 1987.

How investigators used DNA and pizza to catch the killer
Police discovered the first remains in 2010 while searching for a missing woman. A new task force linked the architect to a green pickup truck in 2022. Detectives used a discarded pizza crust to match his DNA to the victims finally. Investigators found a vault with nearly 300 weapons inside his basement floor recently. The suspect used burner phones to lure his victims before their sudden disappearances occurred. They arrested the suspect on a Manhattan street in July of 2023 for murder.
