Los Angeles (CNN) -- Jurors in the involuntary manslaughter trial of Michael Jackson's doctor Tuesday heard dramatic opening statements and a startling recording of the pop singer, his words slow and slurred as he talks about his planned comeback concerts. Prosecutors portrayed Dr. Conrad Murray as motivated by money, while the defense contended Murray's superstar client self-administered a fatal mix of drugs. Witnesses gave varying accounts of Jackson's condition as he prepared for the shows in London. Murray abandoned "all principles of medical care" in attending to Jackson, prosecutor David Walgren said in his opening statement. Defense attorney Ed Chernoff countered, saying Jackson's death was "tragic, but the evidence will not show that Dr. Murray did it."
