A 25-year-old Scottish woman who lay injured in her crashed car for three days because police failed to respond to an accident report has died.

Lamara Bell's family says she died in a Glasgow hospital Sunday, a week after the accident.

She was found Wednesday beside her dead boyfriend John Yuill in a car that had slid down an embankment near the city of Stirling in central Scotland.

Police say the accident was reported, but officers were not sent to the scene until a second call three days later. Police Scotland Chief Constable Stephen House has apologized, saying police "failed both families."

Scottish politicians are calling for an inquiry into how the mistake happened and whether it is connected to police reorganization and budget cuts.
