LAS VEGAS — Trial has been postponed for a man believed to have poisoned himself by keeping the exotic toxin ricin in his motel room, just off the Las Vegas Strip.

U.S. District Court Judge Robert C. Jones on Thursday reset trial to Sept. 9 for Roger Bergendorff.

The court record says defense lawyers and prosecutors agreed to more time. Trial had been scheduled to start Tuesday in federal court in Las Vegas.

The 57-year-old Bergendorff is charged with possession of a biological toxin and weapons violations. His attorney, Paul Riddle, says there have been talks about a plea deal.

Bergendorff was taken into custody April 16, after two months in a Las Vegas hospital. Authorities say Bergendorff admitted making and keeping ricin for protection against unspecified personal enemies.

In Utah, his cousin, Thomas Tholen, faces charges related to the case.
