Sinn Fein president Mary-Lou McDonald has expressed support for the family of Noah Donohoe.
The 14-year-old pupil at St Malachy’s College, in Belfast, was found dead in a storm drain in the north of the city in June 2020, six days after he went missing.
His mother Fiona is hoping to secure answers to some of the questions surrounding his death through the ongoing inquest process.
She has raised concerns around a number of folders of sensitive police material.
