LOS ANGELES,July8（Xinhua）——Michael Jackson's burial remained a mystery as part of his brain is being held by the coroner's （验尸官）office for tests, an official said.
The late superstar's body was transported to an undisclosed place Tuesday after a star-crowded public memorial service at the Staples Center in downtown Los Angeles. It is still unclear where and when the singer's body will be buried.
Ed Winter, assistant chief coroner said families often wait for mass of brain part to be returned before permitted burial. He said he understood no burial would take place immediately although he was not aware of instructions from the Jackson family. The coroner's office released a death certificate(证明) for Jackson Tuesday that listed the cause of death as "delay."
Michael Jackson，the King of Pop，was born on August 29，1958，and died on June 25，2009 after being rushed to a Los Angeles hospital from his rented house when his heart stopped functioning properly. A police investigation into his death is focusing on the possibility that his death was caused by a medication overdose（过量）, including possibly Diprivan, a powerful sedative (镇静剂)usually used for general anesthesia（麻醉）.
