A man killed when two cars carrying members of the same family crashed into a Derbyshire river has been named.
David Cox, who worked at the BBC in Salford, skidded off a bridlepath north of the A6 in Buxton.

His wife's car went into the River Wye about five minutes later. Derbyshire Fire and Rescue said the "weather certainly contributed".
Mr Cox's daughter, who was in the car with him, escaped, as did his wife and son from the other car.
The first crash happened at about 08:30 GMT, when 42-year-old Mr Cox's Toyota Aygo is believed to have slid on an area of snow or ice while driving his daughter to school.
After the car went into the river, his 11-year-old daughter Tess managed to escape but her father remained trapped.
Minutes later, Ruth Cox's Toyota Rav4 is believed to have slipped on the same part of the road, before it plunged into the river.
The 39-year-old mother and her son Ioan, nine, were both able to get out of the vehicle and swim to safety, Derbyshire Police said.
'Shouting for help'The family, from nearby Blackwell Mill, were treated at Stepping Hill Hospital in Stockport, Greater Manchester, where Mr Cox later died. Mrs Cox and the two children have since been discharged.
It is believed that Mr Cox was trapped for about 40 minutes.
Neighbour Victoria Bamber, 32, said his son Ioan ran down the country lane shouting for help.
She said: "He came banging on the door saying 'There's been an accident, Daddy is trapped'.
"When I got to the scene, I could only see the silver 4x4 upside down in the water and Ruth was desperately trying to find David."
She said she waded into the freezing cold water to try to help Mr Cox and, after locals managed to drag him out, emergency services personnel began resuscitation attempts on the riverbank.
Both cars were recovered from the scene of the accident, which is around half a mile from the family's home.
Mr Cox, who had been at the BBC since May 2010, was a member of the Future Media team at Salford, and had worked on the red button service during the Olympics.
Roux Joubert, head of TV and mobile platforms, said: "David was an important member of the team and played a central role in the department.
"He will be sorely missed by everyone here and our thoughts are with his family at this time."
Tim Davie, the BBC's acting director general, said: "We are very sad to learn of David's tragic death.
"He was a popular member of the Future Media team in Salford and had been key to the success of the red button service during the Olympics in the summer.
"Our thoughts are with his family, friends and colleagues here at the BBC at this difficult time."
Derbyshire Police said an investigation is ongoing into the circumstances surrounding the crash, and a file will be prepared for the coroner in due course.
