LISTEN: The M9 crash - one year on
Are Police Scotland's control rooms still at breaking point?
It has been one year since Police Scotland failed to respond to a deadly crash on the M9 for three days - and today we're hearing that there are concerns it could happen again.
25-year-old Lamara Bell and 28-year-old John Yuill were travelling back from a camping trip along the M9 near Bannockburn, when they crashed into woodland alongside the motorway.
It would be three days until they were discovered by police, and by then John was dead, and Lamara was seriously injured.
At the time, a member of the public called 101 to report the accident - it was answered by a sergeant but the details were not logged. It wasn't until a second emergency call was made by a passerby three days later that Police Scotland eventually got to the scene.
When police found Lamara, she was conscious and was trying to escape the vehicle. She was seriously dehydrated, but was able to tell police her name.
She was rushed to hospital, but died a week later.
Now 12 months on from the tragedy - thoughts have turned to whether any lessons have been learned.
