How did Steve M Clark die?

Steve Clark died of an overdose of a mixture of prescription drugs and alcohol. He was mixing Valium, Prozac, codein, morphine with an excessive amount of alcohol, which led to all body systems failing. His blood alcohol level was .30, which was three times the British legal driving limit and twice what killed the famous drummer John Bonham. It was not suicide; it came as a complete accident. He died on January 8th, 1991.
