Michael Jackson will be buried without his brain in a private ceremony on Tuesday by his family. The pop star, 50, died after a suspected cardiac arrest on Tuesday but the circumstances around his death continue to baffle the investigators.

Michael Jackson's brain was taken out to conduct neuropathology tests to seek clues to his sudden collapse and demise, the Daily Mirror reported.

Los Angeles Coroner's spokesman Craig Harvey confirmed that neuropathology tests will be carried out on the legend's brain to see if it holds any clues to the exact cause of his death, said the newspaper.

Sources at the coroner's office revealed that his brain was removed before his body was released to relatives two days after his death, last Tuesday.
