Dr. Murray Feels Vegas Heat Over Child Support

We know now why the law is after Conrad Murray -- and it's completely unrelated to the Michael Jackson investigation.

Nenita Malibiran claims Dr. Murray -- who fathered her 10-year-old son -- is currently behind in child support payments. Malibiran, who now lives in the Sacramento area, obtained a judgment last month in San Jose, CA for $13,311.47.

The judgment was sent to the District Attorney's office in Las Vegas, which honors and enforces child support judgments from out of state.

Yesterday, the D.A. went before a hearing master (not a judge), who is supposed to hear the evidence and recommend appropriate action to a judge. Dr. Murray was ordered to appear but was a no-show.

The hearing master recommended that a bench warrant be issued against Dr. Murray. Dr. Murray has 10 days from yesterday to come into court and deal with it -- otherwise the judge will issue a warrant.

Malibiran's former lawyer, Julie Brown, tells TMZ Dr. Murray was "habitually behind" on child support payments and was always "hiding income."
