Did a man call the family of a woman he had just killed...to taunt them? A police investigation is underway. Four bodies were discovered back in December, along a stretch of highway on Long Island. One of the victims was 24 year old Melissa Barthelemy who moved to New York City, from Buffalo, four years ago. The New York Daily News reports that Barthelemy's sister received taunting phone calls from a man on July 16th, 19th and 23th, back in 2009. That's just days after Barthelemy was last seen alive.

"We believe that each of the four victims met their prearranged client or clients shortly before their deaths and that their deaths are result of their business as prostitutes," stated Sufflok Couinty District Attorney, Thomas Spota at a news conference held earlier this week.

Because of the connection to the internet site...down state media outlets have dubbed the perpetrator the "Craigslist Killer". Each of the four victims vanished sometime in the past four years. The calls to one of the victims sister's has police wondering if the killer himself was on the other end of the line. The calls came from Barthelemy's own phone.

The Daily News describes the man's voice as menacing. "Do you know what your sister is doing? the caller said. The calls came from Manhattan, but police were unable to follow the cell phone any further. Police say the women...all in their 20's were murdered elsewhere, then dumped by the killer on the side oF Ocean Parkway.
