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.

In this episode of Lines of Enquiry: Case Notes producer Siobhan Maguire steps out from behind the scenes to share a significant update on one of season one’s most troubling stories, the death of 23 year old Kelly Lynch in Monaghan. Siobhan outlines new findings from an independent pathology review commissioned by the Katie Trust, including questions over the original cause of death, issues around a lack of evidence, and indications that third party involvement may no longer be ruled out.
She and John discuss what this could mean for the ongoing investigation, the unanswered questions faced by Kelly’s family, and the implications of decisions made in the crucial early hours of the case.
Then, Siobhan turns interviewer, putting your questions to John about his time in An Garda Síochána, the emotional impact of revisiting difficult cases for the podcast, and what listeners can expect from season three of Lines of Enquiry.
Lines of Enquiry returns next week, on Tuesday 14th April.

In this episode of Lines of Enquiry: Case Notes, retired Detective Superintendent Frank Keenaghan takes us inside one of the most shocking cases in recent Irish history, the abduction and murder of 24 year old student Jastine Valdez.
Frank led the frantic 24 hour search in May 2018, from the first early morning briefing to the moment a member of the public spotted the suspect’s car, and the dramatic scene where Mark Hennessy was shot by gardaí.
Frank explains the race against time in a live abduction, the critical decision to release the suspect car’s registration to the public, and how small details, including a blood soaked note and a single guard’s instinct on a Wicklow hillside, ultimately led to finding Jastine’s body.
Drawing on 40 years in An Garda Síochána, he reflects on the emotional toll of cases like this, the importance of public cooperation, and why gut instinct still matters alongside procedure and forensics.
