*Michael Jackson’s former doctor, Conrad Murray, is back in Nevada practicing medicine while awaiting trial in connection with the singer’s death, according to the AP.

The cardiologist pleaded not guilty Monday in Los Angeles to an involuntary manslaughter charge and faces up to four years in prison if convicted.

Dr. Murray was in Las Vegas making arrangements to work from another physician’s office pending an April 5 evidentiary hearing in Los Angeles, said Miranda Sevcik, spokeswoman for Murray and his lawyer, Edward Chernoff.

“We’re not sharing the location because the doctor’s primary concern is for his patients’ privacy,” Sevcik said from Houston.

He moved his practice, Global Cardiology Associates, out of a Las Vegas office building in August, said Mary Russell, property manager for the building across Flamingo Road from Desert Springs Hospital.

Nevada authorities were aware that as a condition of Murray’s release on $75,000 bail, a judge in Los Angeles barred him from administering any anesthetic agent, specifically the drug propofol. The Los Angeles coroner cited propofol as the cause of Jackson’s death, with other drugs as contributing factors.

Murray, who had been hired to look after Jackson’s health during a comeback tour, told police he gave the entertainer propofol and other sedatives to help him sleep. Chernoff has said nothing Murray gave Jackson should have killed him.

The 56-year-old doctor is licensed to practice medicine in Nevada, Texas and California, although the California Medical Board is preparing to seek removal of his license there. He continues to operate the medical practice in Houston that he resumed in November, Chernoff said.
