The inquest into the deaths of two men who died on the A413 has been pushed back once again because a report into why police left the scene of an earlier crash is still not ready.
Malcolm Tindall, 64, and Carl Bird, 29, died on March 4 last year in a car crash close to Great Missenden. in icy conditions.
Following the tragedy, it was revealed that police left the same location after another crash around 20 minutes before the fatal accident.
The Independent Police Complaints Commission is looking into why officers did not do more to warn motorists about the ice on the road.
At the third pre-inquest review on Wednesday, senior coroner Richard Hulett heard that the report still was not ready.
Mr Hulett said: “It is disappointing. I’m stuck in terms of setting a date for the hearing without having the report and not knowing when that is going to be ready.”
The full hearing is not expected to be scheduled until late September or early October.
