Suffolk medical examiners are conducting an autopsy to determine the woman’s identity and cause of death.Suffolk police said their homicide squad detectives responded to the scene in Hempstead along with their Nassau County police counterparts.

Only half of the remains have been identified and no suspects have been named.Homicide Squad detectives are continuing the investigations. Suffolk police ask anyone with information on the Bay Shore or Gilgo cases to call them at 631-852-6392 or Crime Stoppers at 1-800-220-TIPS. All calls will be kept confidential.
