The New York architect accused of killing multiple women and leaving their bodies along the Long Island coast had detailed plans for his crimes on his computer, prosecutors revealed Thursday as they filed charges against Rex Heuermann for two more murders.
Heuermann, 60, appeared in court to face charges in the deaths of Jessica Taylor and Sandra Costilla, two young women long suspected of being victims of men targeting sex workers.
He had already been accused of killing four other women in what’s known as the Gilgo Beach serial killings.
Taylor vanished in 2003. Costilla was killed 30 years ago, in 1993, suggesting prosecutors now believe Heuermann was killing women for a much longer time than previously thought.

The new charges followed recent police searches of Heuermann’s home in Massapequa Park and a wooded area on Long Island linked to the investigation.
Prosecutors said they used new forensic testing to match hairs found near both victims to a DNA profile likely belonging to Heuermann.
They also found a file on a hard drive in his basement outlining his killings in detail.
The document, written in all caps, lists tasks to complete before, during, and after each killing, along with practical tips for “next time.” Entries include reminders to clean the bodies, erase evidence, “get sleep before hunt,” and “have story set.”
