Dad 'kills four kids in death trap car'.
Mechanic Nigel Gresham has been accused of causing death by dangerous driving after the accident which left four of his seven children dead.
The 37-year-old was at the wheel of his modified Land Rover when it flipped off the road at Tattershall Bridge, Lincolnshire, and rolled into the River Witham.
His children, Willow, two, Angel, four, Thor, six, and eight-year-old Keavy died.
Gresham, his partner Sara Bolland, 31, and their eldest children, Liam, 14, Amber, 11, and Star, 14, survived the crash in September last year.
Lincoln Crown Court heard the Land Rover was made up of parts from four different cars and had many "ill-judged" modifications.
Repairs and maintenance of the car were "incompetent", the jury was told.
Timothy Spencer, QC, prosecuting, said Gresham was driving at up to 60mph when a Transit van towing a trailer of canoes approaced from the opposite direction.
He pulled over to the near side but a bracket close to his rear axle snapped.
This caused the car to turn on its side before flipping over and rolling down the bank.
Mr Spencer said: "Of course this was a tragedy. No one suggests that Mr Gresham deliberately intended to endanger the lives of his family.
"But it was an avoidable tragedy. He must have known, despite what he said to police, that this was a defective vehicle.
"He should not have been driving in the manner that he was on that day."
Gresham, of Chapel Hill, Lincolnshire, denies all charges. The case continues.
