Source: Jackson's doc to be arraigned Friday

LOS ANGELES (AP) - Michael Jackson's doctor is set to be arraigned Friday on a charge connected to the pop singer's death, a source told The Associated Press on Wednesday.

Dr. Conrad Murray is to be arraigned at a courthouse near Los Angeles International Airport, according to a person familiar with the planning, who declined to be named because of the sensitivity of the situation. The person didn't say what Murray would be charged with.

Prosecutors have declined to say whether they will charge Murray. Two law enforcement sources have told the AP that prosecutors plan to charge Murray with involuntary manslaughter. The officials requested anonymity because they are not authorized to publicly discuss the case.

Los Angeles County district attorney's spokeswoman Sandi Gibbons said she could "neither confirm nor deny" that Murray would appear Friday afternoon at the LAX courthouse. She noted that the office has a policy of filing charges in the court district where the alleged crime occurred. Jackson died June 25 at a rented mansion on the west side of Los Angeles. The LAX courthouse handles criminal cases in the western portion of LA.

Murray and his lawyers met Wednesday to discuss their client's defense strategy in the event he's charged in the singer's death.

Murray and his legal team had received no word from prosecutors about a decision from the district attorney, but lead attorney Ed Chernoff said his client was ready to surrender to authorities in the event a charge is filed.

"We are prepared for whatever occurs," Chernoff said. "We have time to meet and strategize for possible scenarios, but in reality we've had eight months to do that."

The arrival of Murray and Chernoff in recent days from Houston led to a new round of speculation that a charge could be announced this week. Camera crews and reporters converged on a downtown criminal courthouse Tuesday morning awaiting word of possible charges, although Gibbons said she had no word on when any developments were likely.

Chernoff was waiting for news in a Los Angeles-area hotel, while Murray was at a friend's house in Santa Monica, where a crowd of paparazzi was waiting outside.

"There's no joy in representing someone who shouldn't be charged in the first place," Chernoff said. "There's some truth to the proposition that the waiting is the hardest part."

Police have been investigating Murray since Jackson's death at age 50. The doctor told detectives he'd given the singer a powerful anesthetic and other sedatives to get the chronic insomniac star to sleep. Jackson died soon after and investigators have been gathering evidence to try to show Murray was negligent in administering the drugs.

Murray maintains nothing he gave Jackson should have killed him.

Meanwhile Wednesday, a judge in Las Vegas found Murray in default on a nearly $132,000 debt related to office medical equipment and services.

Murray had no lawyer in the case. He has long-standing personal and professional debts, and faced near foreclosure last summer on his Las Vegas country club home.
