A man who stabbed a retired solicitor 39 times after a crash between their cars has been given life and will serve at least 10 years.
Matthew Daley, 35, killed Donald Lock, on the A24 in Findon, near Worthing, last July after the 79-year-old ran into the back of his vehicle.
He was convicted of manslaughter after he admitted stabbing Mr Lock to death, claiming diminished responsibility.
Daley was told he would initially serve his time in a secure mental hospital.
Lewes Crown Court heard Daley had paranoid schizophrenia and his mother, Lynda, had pleaded with mental health experts to have him sectioned.
