A ‘blueprint’ for murder: Inside the document prosecutors say Rex Heuermann used to ‘plan out his kills’

An architect by trade, Gilgo Beach killings suspect Rex Heuermann allegedly kept a chilling “planning document” to “methodically blueprint” – in the words of prosecutors – how to select, kill and dispose of his victims. Investigators recovered the Word document Heuermann allegedly created in 2000 and modified over several years on a hard drive in the basement of his suburban New York home, where he lived with his wife and children. In capital letters, the file outlined the “packaging” of bodies for transport, steps to avoid apprehension and the removal of trace DNA evidence, according to a bail application released Thursday, when Long Island prosecutors brought charges against Heuermann in two additional killings. “His being an architect is totally consistent with the hyper attention to detail that is manifested in his murders,” criminologist and author Scott Bonn told CNN via email. He now faces charges in the deaths of six women across three decades and multiple communities. On the day Heuermann pleaded not guilty to the latest charges of second-degree murder in the 2003 death of Jessica Taylor and the 1993 death of Sandra Costilla, prosecutors revealed the content of the manual they said he used to “plan out his kills” with scrupulous and fanatical attention to detail. “I’ve never seen a written document such as this,” Suffolk County District Attorney Raymond Tierney told CNN.
