Convicted murderer Robert Durst's health is improving, appeal pending

The health of convicted murderer Robert Durst, 78, subject of the HBO crime documentary "The Jinx," has been upgraded to fair condition, California prison officials say.

The report seems to mark an improvement in Durst's health, as just two weeks ago prison officials told CNN Durst's condition was considered serious. The heir to a New York skyscraper empire is being housed at the California Health Care Facility in Stockton and is battling bladder cancer, among other health ailments.

"The facility cares for the state's sickest incarcerated men," said Terry Thornton, spokesperson for the California Bureau of Prisons.
