Derbyshire Fire and Rescue say the wintry weather was a 'contributing factor' in the accident in which a family in two cars plunged into a river, killing dad David Cox.
Today there is no evidence of the tragedy that had unfolded along the snowy and icy bridleway which runs close to the River Wye, not far from the A6.
Both cars were recovered from the scene of the accident late yesterday afternoon.
Derbyshire Police said an investigation is under way into the circumstances surrounding the crash and a file will be prepared for the coroner.
