Police return to Elli Williams A9 death scene
Police investigating the death of a 16-year-old girl who was hit by a series of cars on the A9 have returned to the scene of the crash.
Elli Williams was found on the A9 southbound carriageway near Auchterarder, Perthshire, shortly after 2200 GMT on 4 January.
Officers are hoping to speak to drivers who were on the same stretch of road last week.
The full circumstances of the incident are still being investigated.
Tayside Police said the public response to appeals for information had so far been "excellent".
Insp Grant Edward said: ''We are returning to the scene tonight to stop and speak with both north and southbound drivers.
"Our hope is that we will be able to identify people who travelled through the scene of the accident on the A9 a week ago and who we have not spoken to so far.
''They could have information that helps us to fully establish what happened to Elli at and around the time of this tragic incident.''
The road checks will be run between 2100 GMT and 2300 GMT.
Elli, from Auchterarder, was the eldest of four children and a pupil at Morrison's Academy in Crieff.
Her family and local community have spoken of their "devastation" at her death.
The 16-year-old was with a group of friends before she was found on the road. She had been hit by up to five cars.
