Jackson death was 'not suspicious'
Medical experts say they are not treating the death of pop star Michael Jackson as suspicious.
But working out the exact reason for Michael's death could take several weeks, after doctors ordered tests.
They want to find out what kind of chemicals might have been in his body when he died.
Michael Jackson's body has now been given back to his family but there haven't been any details about his funeral yet.
The singer died in Los Angeles on Thursday at the age of 50.
Police in the US have also spoken to Michael's personal doctor, Dr Conrad Murray, who was one of the last people to see him alive.
A spokeswoman said the doctor was not under criminal investigation, but his car is being examined to see if it contains any medication or evidence that may help find out why Michael died.
People around the world continue to pay tribute to the star.
On Friday night thousands of fans came together in London's Trafalgar Square to light candles and sing some of his biggest hits.
Often called the King of Pop, Jackson will be remembered as one of the greatest entertainers of all time, having sold more than 250 million albums around the world.
One of those, Thriller, is still the biggest-selling album ever, selling 61 million copies. That's almost one copy for every single person living in the UK.
