Ex Michael Jackson MD In Court

The physician being investigated in pop superstar Michael Jackson's death has appeared in a Las Vegas courtroom to make a payment in a separate child support case.

A court official said Dr. Conrad Murray personally made a $1,003 payment Monday in open court for a California woman and her 11-year-old son.

Murray's lawyer is Chris Aaron. He says a Family Court judge set a July 12 hearing to ensure Murray sticks to a payment plan approved in November. That agreement kept Murray out of jail for failure to pay $15,500 previously owed.

Murray has not been charged with a crime. But Los Angeles police are probing whether he improperly administered the powerful anesthetic propofol to Jackson in the hours before the singer died June 25 in Los Angeles.
