VANISHED � AN INTENSE MANHUNT FOR AN AMERICAN WOMAN WHO DISAPPEARED IN IRELAND OVER A DECADE AGO LEADS INVESTIGATORS TO A POSSIBLE SERIAL KILLER, ON ABC NEWS� �20/20,� FRIDAY, JUNE 9

�20/20� reopens the files on a haunting international mystery that unfolds in Ireland, but begins with a young woman from America. It is a cold case that recently became hot again as investigators now close in on the answers to the disappearance of a number of young women around Dublin over a decade � including 26-year-old American Annie McCarrick. McCarrick, the daughter of a retired New York State Parks policeman, traveled to Ireland from the U.S. to pursue her love of Irish literature and culture. She never returned. �20/20� co-anchor Elizabeth Vargas reports on this young woman�s disappearance -- which became the focus of one of the largest manhunts in Irish history -- on the belief of some that she may be linked to the work of a serial murderer, and on the suburban American family caught in a nightmare in a place far from home. �20/20� airs FRIDAY, JUNE 9 (10:00-11:00 p.m., ET) on the ABC Television Network.

The report returns to Ireland to update and expand an hour which originally aired on ABC News� �Vanished� in April 2000.

After months of fear and frustration with Irish authorities, the McCarrick family hired their own private detective and brought in a specialist from London�s Scotland Yard. As the still unsuccessful hunt for Annie continued, more young women began to disappear. Recent reports in the Irish press examine possible links between these cases and a known rapist and murderer.

�20/20� is anchored by Elizabeth Vargas and John Stossel. David Sloan is the executive producer.
