Jackson's doctor arrives in Los Angeles

Michael Jackson's physician has arrived in Los Angeles in anticipation of a decision from the district attorney's office on whether to charge him for the singer's death, a spokeswoman said Tuesday.

Dr. Conrad Murray, who practices in Houston, arrived in Los Angeles last weekend and one of his lawyers, Edward Chernoff, plans to join him, spokeswoman Miranda Sevcik said.

"Dr. Murray is in Los Angeles for a dual purpose - on family business and to be available for law enforcement," Sevcik said. "We're trying to be as cooperative as we can."

There is no official word on when an announcement about any charges might come. David Walgren, the deputy Los Angeles County district attorney handling the case, declined to comment Tuesday.

The district attorney's office has for weeks been working closely with Los Angeles Police Department investigators to build a case against Murray. Two law enforcement officials have told the AP that Murray is likely to be charged with involuntary manslaughter in Jackson's June 25 death from an anesthetic overdose.
