Charges dropped over impeding prosecution in Finglas
Mark Carroll, 34, a man and father of four, was fatally stabbed at a house in the Scribblestown area of Finglas, Dublin 11, in the early hours of 9 June 2024.

Chantelle Harcourt, 34, a woman from Darndale, Dublin 17, was charged with impeding prosecution. A Central Criminal Court jury unanimously convicted Boyd of murder on 22 July 2026 and he was sentenced to life imprisonment on 28 July 2026. The DPP dropped all charges against Harcourt on 1 August 2026 after the jury failed to reach a verdict on the impeding prosecution count.
