Episode Details

In the shadows of Ireland’s infamous Vanishing Triangle lies one of the most heartbreaking and overlooked cases: the disappearance of 22-year-old Imelda Keenan.

On (or around) January 3rd 1994, Imelda vanished from her Waterford city bedsit. She left behind her glasses, handbag, purse, ID, cigarettes, unopened Christmas presents… and her beloved diary. Her fiancé Mark Wall’s account has been fiercely disputed by her family for over three decades.

This episode of Crimes That Haunt Us dives deep into Imelda’s life, the contradictions in the official timeline, the family’s desperate searches, the ignored red flags, the chilling pre-disappearance injuries, and the shocking 2024 Sunday World interview where Mark Wall erupts in a profanity-laced tirade calling the family “a bunch of fking cts” and branding their campaign a “conspiracy theory.”

Now, in 2026, on the 32nd anniversary, Gardaí have issued a fresh appeal with a new age-progression image of Imelda at 54. The silence, they say, “remains unbroken.”

Will this be the year the truth finally emerges?
