THE BRONX - A law enforcement official tells The Associated Press a call made from the cell phone of a slain Bronx woman on the last day she was seen alive came from a Long Island town near where her body was found. The body of Melissa Barthelemy was found along with the bodies of three other prostitutes in mid-December near Gilgo Beach. Barthelemy was last seen in The Bronx on July 12, 2009, but the official says a call made to her voicemail that day came from Massapequa, about 20 miles from where the bodies were found.Her parents filed a missing-persons report after her near-daily calls to them abruptly stopped. A few days after she was last seen, her sister received calls from her cell phone, and a man on the other end said she was a "whore," the official said.In the days after the missing-persons report was made, New York City police tracked the cell phone signal to midtown Manhattan and searched the areas near Penn Station and the Port Authoritybus terminal, but the signal went dead, according to the official. Later, cell phone records obtained through a court order showed the voicemail call on July 12 was made in Massapequa. Police canvassed the area, asking around at local hotels, but turned up nothing, the official said. The thick case file was eventually turned over to Suffolk County to help with the investigation.According to the official, the family also hired a psychic in April 2010, nearly a year after the 24-year-old was last seen. The psychic predicted she would be found in a shallow grave, overlooking the ocean and near a sign with the letter G, which essentially came true. The family later reported the findings to police, theofficial said.The other three victims have been identified as 27-year-old Amber Lynn Costello, of North Babylon on Long Island, Maureen Brainard-Barnes, 25, of Norwich, Conn. and Megan Waterman, 22, of Maine. Investigators say they believe the women probably were slain by a serial killer. The official wasn't authorized to speak publicly about the case and spoke to the AP on Tuesday on the condition of anonymity. AP wire services contributed to this report
