A terror stalked the area of Dublin Ireland in the early 1990s - within a span of 5 years at least 8 young women disappeared without a trace, never to be seen or heard from again. Even to this day, no one has been convicted and no solid leads have been found. All the women disappeared in what is now referred to as Ireland’s Vanishing Triangle.
