EXCLUSIVE: Michael Jackson's Doctor Previously Ordered To Jail

Dr. Conrad Murray is at the center of the Michael Jackson death investigation, with search warrants served on him in Houston and Las Vegas. But the cardiologist is no stranger to problems with the law, in fact, he's twice been ordered to jail, RadarOnline.com learned exclusively.

Murray was sentenced to 10 days in jail on April 29 of this year for non-payment of child support. He was sentenced to 25 days in jail in 2007, also for non-payment of child support. Both sentences were connected to a son he fathered in California with Nenita Malibiran, RadarOnline.com learned. Murray did not go to jail either time; the sentences were stayed while he provided more financial information. He eventually paid enough money to avoid jail.

Investigators have focused on Murray in connection to Jackson's death as sources have reported the doctor administered the powerful anesthetic propofol to the singer. Asked by RadarOnline.com if he gave Jackson the drug, Murray refused to answer, through his lawyer.

A RadarOnline.com investigation revealed that the doctor has a messy personal life and has fathered many children outside of his (second) marriage.

Court records show that, over eight years from 1999 to 2007, Murray did not make any child support payments to his son by Malibiran.

And RadarOnline.com can also exclusively reveal that a second woman, Janice Adams, is accusing Murray of fathering two daughters with her in Las Vegas.

One source familiar with Murray says: "In a deposition given 10 years ago, Murray admitted to fathering six children and said that, although his wife and two children were in San Diego, Ca., he was living with another woman in Phoenix, Az."

Murray is married to Blanche, his second wife. But at least one person says that hasn't slowed down his social life.

Four years ago, Murray was partying with a different girlfriend. Vegas model Maggie Goldstein told a reporter: "I was one of 10 models and promotions girls hired by Conrad Murray to fly to a Trinidad and Tobago resort in 2005 to publicize a new energy drink, Pit Bull, that Murray was producing with a partner.

"Conrad had a ball. He was up into the early hours, drinking, having fun and posing bare-chested with the girls.

"He brought along a girlfriend, Bridget, a black singer from Los Angeles.

"I was shocked to later find out he was married."
