A New York real estate heir pleaded guilty in New Orleans on Wednesday to a weapons charge and agreed to an 85-month prison sentence, a move that could usher in his extradition to California to face murder charges.
U.S. District Judge Kurt Engelhardt told Robert Durst that he will not make the plea final until he reviews a pre-sentencing report due in two weeks.
Durst was charged last year with the 2000 death of his friend Susan Berman after mumbling "killed them all" during the taping of an HBO documentary.
His lawyer, Richard DeGuerin, says Durst did not kill Berman.
McMahon called the plea agreement a "good result."
The maximum would have been 10 years and a $250,000 fine.
