Police in Suffolk County, New York, are investigating ties between a series of killings in Gilgo Beach, where an arrest was recently made, and the 2006 killings of four women whose bodies were found in West Atlantic City. The Press of Atlantic City reports Kim Raffo, Molly Jean Dilts, Barbara Breidor and Tracy Roberts were found in a ditch behind a motel on the Black Horse Pike on Nov. 20, 2006. Their case remains unsolved. Police are now examining the Gilgo Beach murders for ties to the West Atlantic City case after Rex Heuermann was arrested last week in the New York case.
