Conrad Murray Defense to Put Michael Jackson's Life on Trial

The courtroom is expected to be packed with the king of pop's family members today as jurors and Jackson fans learn more about Jackson's last hours. Murray, 58, is charged with involuntary manslaughter and could face four years in prison and lose his medical license.

Jackson died over two years ago at 50 after overdosing on the powerful anesthetic, propofol. The defense will contend that it was Jackson who self-administered the last dose of the anesthesia that ultimately was his death potion. Defense attorneys Edward Chernoff and Nareg Gourjian are expected to argue that Jackson gave himself the dose after Murray left Jackson's bedroom.

"It is not at all implausible in my opinion that he could have pushed an injection into that port and inadvertently killed himself," said Vesna Maras, a former medical prosecutor for the Los Angeles district attorney's office.
