The attorney for the family of a New Jersey prostitute who died near where 10 other victims of a suspected Long Island serial killer were found says authorities have not determined how she died.

John Ray and the family of Shannan Gilbert met with officials from the Suffolk County Medical Examiner's office Tuesday. Gilbert was a 24-year-old escort who disappeared on May 1, 2010. Her remains were found last December.

She was last seen in a beach community several miles from where 10 others, including at least four prostitutes, were killed.

Police believe Gilbert's death is unrelated and have theorized she may have drowned in a marsh.

There are no suspects in any of the cases.

Some officials think more than one killer could be responsible for the 10 deaths.
