Millionaire Robert Durst has been formally charged by a New Orleans-based federal grand jury with illegally possessing a handgun.

The charge in Friday's indictment says Durst violated the federal gun-control act because he was in possession of a firearm after being convicted of earlier felonies. The move came as no surprise: A federal criminal complaint outlining the allegation had been filed earlier this week.

Durst now stands charged with offenses in three jurisdictions in two states: In California, he is charged in the 2000 slaying of Susan Berman. In New Orleans, where he was taken into custody at a hotel last month, he still faces weapons charges in state and federal courts.
