A new TG4 documentary series is to shine a light on the disappearance and murder of Co Tyrone teen Arlene Arkinson in 1994.
15-year-old Arlene was last seen on 14 August 1994 as she left her home in Castlederg to attend a disco in Bundoran, with her body never being found.
In 2021 a coroner ruled that convicted child killer and rapist Robert Howard was responsible, on the balance of probabilities, for the death of the Co Tyrone schoolgirl.
