A student who was knocked down by a hit-and-run driver after a night out to celebrate the end of her exams phoned her mother to tell her she was dying.
Police are appealing to the public for information
Kate Sheedy, 18, was run down near the entrance to an industrial estate in Isleworth, west London, just after midnight on 28 May.
As she lay on the ground she used her mobile phone to call her mother.
Ms Sheedy is in hospital in a critical life-threatening condition with severe internal injuries and broken bones.
During the day the sixth-form student had delivered a speech at a leaving ceremony at Gumley Convent School in Isleworth, west London.
She then went out to celebrate the end of school with friends.
After Ms Sheedy was knocked down she was able to tell her mother where she was.
Mrs Sheedy rushed there and found her lying on the pavement.
"No mother wants or expects to be phoned by their own child saying that they have been run over and that she thinks she is dying," she said.
"When I found Kate on the pavement her first concern was for her pink shoes - these she had bought for her 18th birthday."
She described her daughter as a "beautiful, hard working girl".
"She had hoped to go to university in September to study history and politics," Mrs Sheedy said.
She has worked so hard for these exams and now it has all been taken away from her."
Police have renewed their appeal for information.
