A heartbroken mother said her family were "shattered" after a horrific collision left her 16-year-old daughter dead and two other teens badly injured.
Kimberly O'Connor was a transition year student from Terence MacSwiney College.
"Our lives are shattered today and it is difficult to put into words how we are feeling," said her mother, Jennifer.
"Our hearts are broken at the loss of our beautiful daughter, sister, granddaughter, aunt, niece and friend.
"Kimberly had a bright future and was a very kind and generous person who was loved by so many people."
Kimberly had travelled to Calcutta in India just last month as a volunteer with an Irish charity working to help disadvantaged children.
Two 17-year-old boys, both passengers in the car, were hurt in the single-vehicle crash, one of whom was last night fighting for his life.
The driver of the car, a 16-year-old boy, fled the scene on foot.
He later presented himself at a Cork hospital for treatment of non-life threatening injuries.
The crash happened at 11.45pm on Wednesday when the car apparently hit a road sign, and ploughed into a garden wall outside a house on Harbour View Road in Knocknaheeny, Co Cork.
Despite desperate efforts by paramedics to help Kimberley, who was a front seat passenger, she was pronounced dead at the scene.
Principal of Terence MacSwiney College, Phil O'Flynn, said the school was shocked by the death and the injuries suffered by two others.
"This is a terrible tragedy for the families of the students, our school and our community," she said.
Ms O'Flynn confirmed the college had put its critical incident management plan into action.
"The school is open to students, parents and the wider community - staff members, including counselling personnel, are on site to offer support," she said.
