Costilla's body was found on November 20, 1993 in North Sea, New York. She hasn't been listed as a prostitute by investigators yet, however detectives have said that Costilla led a "similar lifestyle".
Long Island Serial Killer suspect
After Bittrolff's sentence, the case's prosecutor announced that Bittrolff was also a suspect in at least one of the 10 murders attributed to the unidentified Long Island Serial Killer in New York's Suffolk and Nassau counties. Suffolk County District Attorney’s office prosecutor Robert Biancavilla released a statement noting that Bittrolf was likely responsible for the deaths of other women, and that "There are remains of the victims at Gilgo that may be attributed to the handiwork of Mr. Bittrolff, and that investigation is continuing". Bittrolff was a carpenter who lived in Manorville, where the torsos of official LISK victims Jessica Taylor and "Jane Doe No. 6" were recovered. The remains were discovered roughly three miles away from Bittrolff's home. He was also a hunter who seemed to enjoy killing and mutilating animals, and reportedly once "cut out the heart of a deer he had just shot and ate it raw in the woods". Another link between Bittrolff and the Long Island Serial Killer case became apparent when it was revealed that the grown daughter of Rita Tangredi, one of the women that Bittrolff was convicted of killing, was reportedly "best friends" with Melissa Barthelemy, who was one of the first LISK victims discovered strangled and wrapped in burlap at Gilgo Beach. Barthelemy's mother also reported that Melissa "had a lot of calls to Manorville from her phone" at the time.
