Katie Allan, a 20 year old student who was studying at the University of Glasgow, had consumed four pints of cider before driving home from a pub. She was jailed for 16 months earlier this year, after she hit a 15-year-old boy, who was out running at the time.
Today, it was announced that Allan has died in prison. Further details have not been released, but a Scottish Prison Service spokesperson said: "We can confirm Katie Allan passed away at Polmont. A fatal accident inquiry will be held."
In the collision, the runner was left unconscious and bleeding, with a broken ankle and a fractured eye socket.
Allen left the scene of the collison but a witness passed on her car registration to police, who found at home.
She pled guilty to causing serious injury to the teenager by driving dangerously, and driving with 87 microgrammes of alcohol in 100ml of breath - more than four-times the legal limit.
