The parents of Ana Kriegel will plant a tree in St Catherine's Park in Leixlip in Co Kildare tomorrow in remembrance of their daughter.
A plaque will also be unveiled by Geraldine and Patrick to pay tribute to Ana, who was killed at a derelict farmhouse in May last year.
Earlier this month, two teenage boys were convicted of the 14 year old's murder.
Local TD Catherine Murphy says tomorrow's event will be a small one to mark Ana's life:
"It's just to mark Ana's life"
