Monkees star Davy Jones died of a heart attack, a post-mortem examination has confirmed.
The report says the 66-year-old had severe build-up in his arteries.
Toxicology reports came back negative for any sign of drugs in his system other than cannabinoids, a class of drugs that includes marijuana. However, that played no role in his death.
British-born Davy rocketed to the top of the Sixties music charts with The Monkees, captivating audiences with hits including Daydream Believer and I'm a Believer.
He died on February 29 in the stables of his home in West Palm Beach, Florida.
