Police have released the names of four family members killed in a head-on crash between a car and a lorry on one of Britain's most dangerous roads.
David Cockburn, 48, his daughters Carley Ann Cockburn, 21, and Bethany Cockburn, 18, and Bethany's 23-month-old daughter Lacie Jade Stephenson died in the accident near Grimsby, North East Lincolnshire on Friday afternoon.
The fifth family member is yet to be formally identified, Humberside Police said.
The family, who were from the Chester-Le-Street area of Durham, were travelling to a dance competition at Butlin's holiday resort in Skegness, Lincolnshire at the time of the collision. They were travelling with friends who were in other cars, police said.
The crash happened at 12.30pm on Friday near Oaklands Hotel on the A18 Grimsby Road, in Laceby, when the family's Nissan Primera was in collision with a light goods vehicle.
Three members of the family died at the scene and two others died later in the nearby Diana Princess of Wales Hospital.
The driver of the lorry is thought to have sustained minor injuries.
Operations Superintendent Tracy Bradley, of Humberside Police, said: "Our deepest thoughts go out to the family and friends of those who were tragically killed in this collision which happened on the A18 yesterday. We are working closely with relatives of those who lost their lives and are supporting them through what will be a very difficult time.
"Roads policing officers are working closely with our collision investigation team to piece together the evidence we have gathered in order to try and determine what led to this tragic incident taking place and took the lives of those travelling in the Nissan at the time. We have spoken to a number of key witnesses already, however, if anyone saw the incident but has not come forward I would ask them to do so."
The Grimsby stretch of the A18 featured in a BBC television programme, Britain's Most Dangerous Roads, in 2011, which claimed it was 25 times more dangerous than the average British motorway with 20 crashes in the previous three years. It was also found to be the UK's highest-risk stretch of road for car drivers in a nationwide survey by the Road Safety Foundation in 2010.
