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.

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.

Case Notes #006: The Kelly Lynch Update

Tue, 07 Apr 2026 06:00:00 +0000

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.

Case Notes #005: The Search for Jastine Valdez

Tue, 31 Mar 2026 06:00:00 +0000

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.

Case Notes #004: Capturing The Courtroom

Tue, 24 Mar 2026 07:00:00 +0000

In this episode of Lines of Enquiry: Case Notes, renowned courtroom artist Mike O’Donnell takes us inside the hidden world of Ireland’s criminal courts as seen from his sketchpad. In his day to day, Mike sits just feet away from judges, juries, gardaí, families and some of the country’s most high profile defendants, capturing not only the people in the dock but the tension, emotion and fragile humanity of the courtroom itself.

He explains how he became Ireland’s first full time professional courtroom artist, and how his process has developed over the years, moving to ink and learning what exactly to look for when trying to distill an entire trial into a single image.

Mike reflects on what it is like to sit behind some of Ireland’s most notorious figures and study them at close range, from a Bible waving Enoch Burke to Conor McGregor losing his temper, and even having tart and tea with Gerry Hutch as he draws him in his home. He shares what years of observing faces in murder trials, gangland prosecutions and other high stakes cases have taught him about the best and worst of human nature.

Case Notes #003: Cold Case Breakthroughs

Mon, 16 Mar 2026 19:00:00 +0000

In this episode of Lines of Enquiry: Case Notes, former Garda Detective Sergeant Alan Bailey takes us inside the hidden world of cold case investigation. With more than 200 unsolved homicides sitting on the desks of just eight detectives, he explains how and why an investigation goes cold, what it takes to justify reopening a case, and why there is always still hope.

Alan talks through some of the most significant cases he worked on, including the murder of Nora Sheehan. He reflects on the impact of modern forensics and the importance of preserving evidence, that allowed this case to be solve four decades after it happened.

Having been a lead detective on Ireland’s most prolific missing women cases, which became known as the Vanishing Triangle, Alan shares the immense challenges of working on cases with no suspect, and sometimes no body. After searches for some of these women began again recently, he shares what it takes to trigger new digs and how seemingly minor details can suddenly become pivotal.

Philip Cairns: The Lost Boy

Tue, 24 Feb 2026 07:00:00 +0000

In October 1986, 13-year-old Philip Cairns became one of the most recognisable faces in Ireland.

The boy left his home in Dublin to walk back to school after lunch and vanished without a trace. His disappearance gripped the nation, changed how parents viewed their children’s safety, and left a family living with unanswered questions for nearly four decades.

In this episode of Lines of Enquiry, John revisits one of Ireland’s most haunting missing person cases and asks what really happened to the boy who never came home.

An Garda Síochána have told us the investigation into the disappearance of Philip Cairns remains active and ongoing. Gardaí are keen to speak to people who may have been young at the time Philip disappeared and not in a position to talk to them, but who may now feel able to come forward.

Even the smallest piece of information could help investigators. Anyone with information is asked to contact Rathfarnham Garda Station on 01 666 6500, the Garda Confidential Line on 1800 666 111. If for any reason, you do not feel comfortable making that contact directly, you can email linesofenquiry@goloudnow.com and we will ensure that any credible information is passed on to investigating Gardaí on your behalf.

Tue, 17 Feb 2026 07:00:00 +0000

In August of 1987, 19 year old Trevor O’Keeffe embarked his journey home to Ireland after a brief holiday France. He planned to hitchhike across the north of the country, through the vineyards of the world-renowned Champagne province.

Trevor was unaware of the warnings against hitchhiking that had been made to young men across the region. He had not heard the local rumours about a serial killer stalking the area. He did not know about the 6 other young men already disappeared.

Trevor’s body was found in a French forest just days after he began traveling. In this episode of Lines of Enquiry, John explores what happens when a serious crime happens in another country. He asks how different laws, languages and police forces affect the search for answers and the fight for justice.

Case Notes #002: Inside True Crime

Tue, 03 Feb 2026 07:00:00 +0000

In this episode of Lines of Enquiry: Case Notes, John Sweetman is joined by one of Ireland’s leading true crime podcasters, Nules Ní Chléirigh, creator and host of Ireland Crimes and Mysteries.

John and Nules reflect on what draws them to the stories of some of Ireland’s biggest crimes, the realities of working on cases with no clear resolution, and the importance of ethical storytelling when dealing with victims and their families.

They share some of the most impactful cases they have worked on, including those where the smallest detail made a critical difference, and others that have stayed with them long after recording.

The conversation also explores how true crime has evolved as a genre, and the role it can play in prevention, awareness, and in keeping the memory of victims alive.

28 year old mother of two Jasmine McMonagle loved to write and longed to be a children's author one day.

In 2019, a letter she wrote was sent to the Garda Technical Bureau for examination. In the letter, Jasmine wrote of being held hostage in her own home, of threats against her and her daughters, and of how she would no longer live in fear.

In this episode of Lines of Enquiry, John explains how that letter ended up on his desk, and he looks back on a tragic story of rage, loss and bravery, and of a family torn apart by violence.

Antra Ozolina: The Set Up

Tue, 20 Jan 2026 07:00:00 +0000

When Antra Ozolina was found dead in her home in Kilnaleck, Co Cavan in June 2014, from the outset, the explanation seemed straightforward and the case moved quickly towards closure.

But small details did not sit comfortably. The circumstances raised quiet questions. The timeline felt too neat and the version that was accepted left little room for doubt or for scrutiny.

In this episode of Lines of Enquiry, John Sweetman revisits the death of Antra Ozolina, examining how early assumptions can shape an investigation, how quickly a version of events can become fixed, and how the how the easy answer is not always the right answer.

Seamus Ruddy: The Long Search | Part I

Tue, 13 Jan 2026 07:00:00 +0000

In May of 1985, Seamus Ruddy went to meet three men in Paris. They were men he knew from a past life, in Ireland. Seamus had left that life behind, to start a new one in the French capital. His family had asked him not to go to the meeting, but Seamus had been assured he would be safe.

He was never seen again after that night, and his disappearance would lead to a search spanning decades. The Ruddy family refused to give up their hunt for answers, facing down intimidation and holding out hope even against the most insurmountable odds.

This story would eventually join others, as the Ruddy family realised they were not the only ones searching for their missing loved ones, and pushing for answers from a dark period in Irish history. Seamus was eventually considered one of The Disappeared, the group of people suspected of being kidnapped, killed and secretly buried by Republican paramilitary groups during The Troubles.

Jastine Valdez: Abducted in Plain Sight

Tue, 06 Jan 2026 07:00:00 +0000

Jastine Valdez was abducted in broad daylight on a rural road in Enniskerry, Co Wicklow, in May 2018. The 24-year-old had just stepped off a bus that dropped her only a few minutes’ walk from her home. Just moments later, a woman driving along that quiet country road spotted a man seemingly trying to force a young woman into his car.

What followed was a frantic garda manhunt, as they realised Jastine had been abducted in broad daylight – but without any idea who may have done it, or why. What was to follow would be a tragic, terrifying case that would shock all of Ireland.

In this episode of Lines of Enquiry, John Sweetman takes us through that frenetic investigation by gardai moments, and their efforts to seek justice for Jastine, and her family in Ireland and the Philippines.

Mark O'Sullivan: Terror on the Farm

Tue, 16 Dec 2025 07:00:00 +0000

When Anne O'Sullivan was diagnosed with terminal cancer, tensions within her family about who would inherit her substantial plot of farm land came to the surface.

Soon, Anne would find herself awake before dawn, running through fields and ditches to a neighbour's house to get help as a terrible darkness descended on the family farm.

This is a tragic story that saw a family torn apart as their home became consumed by fear and threats of violence towards Anne and her eldest son, Mark. Those rising tensions would lead to the most unfathomable and shocking moment of hatred and rage.

In this episode of Lines of Enquiry, John tracks the descent into violence and revisits his case notes on the letters that proved crucial to any understanding of events of that tragic day.

Nora Sheehan: The Last Walk | Part I

Tue, 02 Dec 2025 07:00:00 +0000

In June 1981, Nora Sheehan left the South Infirmary Hospital in Cork and disappeared into the night. In the hours that followed, she was seen by witnesses walking alone after midnight, a familiar figure on dark roads and quiet streets.

Days later, her battered body was discovered dumped in woodland far from the city. Her murder shocked Cork and marked the beginning of a case that would stretch across generations.

In this opening chapter of a two-part investigation, John Sweetman reconstructs Nora’s final movements, the witness sightings after midnight, and the immediate aftermath of her disappearance. What emerges is the story of a vulnerable woman who vanished in plain sight and a killing that would become one of Ireland’s longest-running cold cases.

Barbara Walsh: Vanished after Dark

Tue, 25 Nov 2025 07:00:00 +0000

The Walsh house in rural Connemara is quiet by 4am on the 22nd of June 1985. Earlier in the night it was full of people celebrating the brief return of two family members who had emigrated. But now the friends, neighbours and even the local Gardaí who had attended the party have all dispersed. So, when 14 year old Jacquie Walsh wakes up in the middle of the night the only person she sees is her mother, 33 year old Barbara asleep on the couch. Jacquie tries to wake her but when she does not stir, Jacquie places a pillow beneath her head and drapes a blanket around her before heading to bed. Barbara Walsh was never seen again.

For years, her family were told that the young mother of 7 must have wandered off – Despite not having a car and living over 50 miles away from Galway city.

In this episode, former Garda forensic detective John Sweetman goes back to 1985 and examines the original investigation, the new leads for the cold case team and asks where is Barbara Walsh?

What began as a desperate search for a missing boy quickly became one of the most emotionally charged murder investigations Ireland had ever witnessed. Thousands turned out to look for him. Gardaí deployed every resource available. For a week, the country hoped against hope. Then came the devastating discovery: Robert had been killed. The search for the young boy soon became a hunt for a killer. The eventual truth would prove to be more devastating than anyone had imagined.

The Beast: The Midlands Letters

Thu, 06 Nov 2025 10:00:00 +0000

A sinister, disturbing handwritten letter arrives into Garda HQ. It has been sent anonymously to a school in the midlands. There are 23 pages, promising terrible crimes to come, and detailing the writer’s twisted plans to abduct and kill teenage girls.

Soon after, two more arrive – again sent to schools across the Irish midlands. Gardai then realise this is not their first encounter with the anonymous writer, as they discover records of a strange hideout found in the woods in Offaly many years ago. More letters arrive, sent to Garda stations and found by members of the public.

Fear spreads as the writer goes further and begins naming potential targets, all teenage girls at a local Offaly school. Gardai now face a race against time to find him, before he can put his evil plans into action.

As part of our launch week of Lines of Enquiry we are releasing two episodes this week, including this one. From next week we will release weekly, every Tuesday morning.

Mary Gough: Death on the Stairs

Tue, 04 Nov 2025 10:00:00 +0000

When 27-year-old Mary Gough was found dead in her home in Balbriggan in 2001, it looked like a tragic accident. Gardaí were called to what appeared to be a fall down the stairs.

But as investigators examined the scene, small details began to raise doubts, marks that didn’t fit, timelines that didn’t match, and a story that started to change.

In this episode, former Garda forensic detective John Sweetman revisits the case, piece by piece, to uncover how investigators learned that what looked like a household accident was, in fact, something far more sinister.
