Suspected Gilgo Beach serial killer Rex Heuermann has been charged in the death of two additional victims.

Heuermann faced a judge Thursday morning. Suffolk County District Attorney Ray Tierney says Heuermann was charged in the 1993 murder of Sandra Costilla and the 2003 murder of Jessica Taylor.

Taylor was recovered in July of 2003 in Manorville and was found decapitated with her hands and arms severed below the elbow and a tattoo obliterated with a sharp object, the DA said. According to the DA, Taylor’s arms and skull were found on Ocean Parkway near the original “Gilgo four” victims.

Officials say Costilla was found dead in 1993 in North Sea and suffered numerous sharp force injuries.

The DA says hairs recovered from both bodies were linked to Heuermann through testing.

According to the DA, Heuermann is also a suspect in the death of Valerie Mack.

The new charges come after a second search at Heuermann’s Massapequa Park home two weeks ago. Sources say investigators removed wood paneling from the basement walls.

Heuermann has previously been charged with murder in the deaths of Maureen Brainard-Barnes, Melissa Barthelemy, Meghan Watermann and Amber Costello.

Heuermann continues to maintain his innocence against all charges.

Heuermann’s family was not in court on Thursday.

An attorney for Heuermann's estranged wife put out a statement saying that "today's indictment further illustrates that, Asa Ellerup has no involved in any of the alleged crimes that her estranged husband, Rex Heuermann, has been charged with."
