Disturbing New Details Emerge in Gilgo Beach Serial Killings - Rex Heuermann Charged with Two Additional Murders-WEEK IN REVIEW

In a significant development in the Gilgo Beach serial killings
case, suspect Rex Heuermann was charged Thursday with the murders
of two additional women, Jessica Taylor and Sandra Costilla. This
brings the total number of his alleged killings to six. The
charges, announced by Suffolk County District Attorney Raymond
Tierney, extend the timeline of Heuermann’s alleged criminal
activities, with the first murder now dated back to 1993.

According to court documents, Heuermann was charged with the 2003
murder of Jessica Taylor, whose remains were discovered in Gilgo
Beach and Manorville, and accused of the 1993 murder of Sandra
Costilla, whose remains were found in North Sea, Long Island.
"The architect and father meticulously planned and executed six
separate murders," said Tierney during a news conference on
Thursday.

A significant breakthrough in the case came from a digital
"planning document" found on one of 350 electronic devices seized
from Heuermann's home in Massapequa Park, New York. This document
contained a checklist detailing how to package a body for
transport, avoid leaving DNA traces, and other steps to ensure
the success of his gruesome acts. There were notes indicating
steps to take "next time," such as considering a hit to the face
or neck and using heavier rope for the neck.

"Heuermann wrote about the importance of sleep to avoid
'PROBLEMS' and to increase what he referred to as 'PLAY TIME,'
believed to reference sexual and mutilation acts on victims,"
court documents reveal. The planning document also included a
"post-event" checklist with tasks to avoid apprehension, such as
"BURN GLOVES," "DISPOSE OF PICS," and "HAVE STORY SET."

Jessica Taylor, a sex worker in midtown Manhattan, was last seen
in the same area where Heuermann worked. Taylor was decapitated
and dismembered, with her remains discovered in stages over
several years. DNA from hair found on a surgical drape underneath
her body helped link Heuermann to her death.

Sandra Costilla, 28, was found in a wooded area in North Sea,
Long Island, in 1993. DNA evidence also connected Heuermann to
her murder. "Pornographic images accessed by Heuermann notably
and largely coincide with how the remains of Taylor and Costilla
were found," prosecutors noted.

Heuermann was initially arrested in July and charged with the
murders of Megan Waterman, Amber Costello, and Melissa
Barthelemy, all escorts whose remains were found in desolate
spots near Gilgo Beach in 2010. He was later charged with the
murder of a fourth escort, Maureen Brainard-Barnes. Six
additional sets of remains were also found in the area.

In court on Thursday, Heuermann pleaded not guilty to the new
charges. His defense attorney reiterated his innocence. Heuermann
remains in custody without bail and is scheduled to return to
court on July 30.

District Attorney Tierney stated that Heuermann is now the
leading suspect in the death of Valerie Mack, whose remains were
found in Manorville near Jessica Taylor’s. Investigators will
continue to review over 30 years of crimes in Suffolk County and
beyond to see what else might be connected to Heuermann.

This case continues to unfold as authorities piece together the
extent of Heuermann's alleged crimes, bringing some measure of
closure to the families of the victims. The investigation remains
ongoing, with the hope that further evidence will emerge to
solidify the case against Heuermann.
