Trying to figure out what exactly caused Michael Jackson's sudden death, police are currently attempting to track down his family doctor to get a few questions answered.

According to Los Angeles police spokeswoman Karen Rayner, police have taken Jackson's physician's BMW into custody - as they want to safeguard any possible evidence that it may contain.

"We have not been able to interview the doctor yet. His car was impounded because it may contain medications or other evidence that may assist the coroner in determining the cause of death," Rayner told The Associated Press.

Meanwhile, Miss Rayner added that the doctor is "not under criminal investigation," but is sought by the coroner's office for questioning.
