Matthew Daley, 35, has been found guilty at Lewes Crown Court of manslaughter on the grounds of diminished responsibility following the so-called "road rage" killing of Donald Lock, 79, in West Sussex.
A mentally ill man has been found guilty of manslaughter on the grounds of diminished responsibility following the "road rage" killing of a retired solicitor.
Matthew Daley, 35, knifed 79-year-old Donald Lock 39 times on the A24 at Findon, near Worthing, West Sussex, on 16 July 16 last year.
Daley stabbed Mr Lock after his Toyota crashed into the back of Daley's Ford Fusion at about 16mph, causing minor damage to both cars.
Before the killing Daley's family had "pleaded" with clinicians to section him as his mental health declined, the trial heard. NHS chiefs have apologised to his relatives for not doing more.
At Lewes Crown Court, Daley was cleared of murder but convicted of manslaughter on the grounds of diminished responsibility.
A review has been launched into ten killings involving people who had contact with the Sussex NHS Partnership trust
