A drug dealer who supplied a young trainee driving instructor with morphine has been jailed for three years.
Dennis Montero admitted supplying Class A drugs to a number of people, including trainee driving instructor Lindsey Wilson. He has been jailed for three years after being sentenced at St Alban's Crown Court.
Ms Wilson was found unconscious at a birthday party in January 2010 and was taken to hospital, where she died 19 days later.
Her parents said the death of their daughter had "left a void that cannot be filled."
