The investigating detective in the Annie McCarrick disappearance believes she died at the hands of a serial killer.
Retired Det Garda Thomas Rock also maintains that the case of the American woman, who vanished without trace almost 30 years ago, is linked to other missing women.
New Yorker Annie was last seen on a day trip to Enniskerry at the foot of the Dublin/Wicklow Mountains in March 1993, shortly after arriving in Ireland to study.
