LONG ISLAND — The disappearance of Shannan Gilbert went from a search for just one woman into the discovery that Gilgo Beach was a dumping ground for bodies. Since police began searching for Gilbert, eleven bodies and sets of remains, including Gilbert's, have been found. The story has taken several twists and turns, and seems to have hit a dead-end, with no suspects and several families left to grieve their loved ones. Holli Haerr reports on the investigation and who could be responsible for this chilling chain of events.
