Ana Kriégel: An Unspeakable Crime

On the 14th of May 2018, Ana Kriégel left her home in Leixlip, Co Kildare, with a promise to her father that she wouldn't be long.

But Ana never came home and her disappearance sparked a three-day search of a local park, the last place where she had been seen walking with another child.

It was a missing person's case that gripped the nation as everyone hoped the smiling girl in her favourite black hoodie would be found. What happened would become one of Ireland's most disturbing and unsettling cases.

In this episode of Lines of Enquiry, John Sweetman takes us back to those dark days of her disappearance, and why her killers will never be named.
