One of the two boys, found guilty of murdering Ana Kriègel four years ago, is due to appeal his conviction today.
Boy B was just 13-years-old in May 2018, when he lured Ana from her home in Co Kildare to a derelict farmhouse in Lucan, Co Dublin, where his friend killed her.
In June 2019, Boy A and Boy B were convicted for their roles in the murder of Kildare schoolgirl Ana Kriègel.
Boy A was handed a life sentence with a review due to take place after twelve years, while Boy B was sentenced to fifteen years detention with a review after eight years.
Their identities can never be revealed because of their ages at the time they murdered Ana.
Boy B is seeking to overturn his murder conviction and has engaged a new legal team for this challenge.
In July of this year, they were refused permission to introduce fresh evidence in the appeal.
Boy A hasn't lodged an appeal. Boy B’s appeal is due to be heard at 10 am today.
