LAS VEGAS (AP) — A man suspected to have been poisoned by ricin found later in his hotel room

LAS VEGAS (AP) — A man suspected to have been poisoned by ricin found later in his hotel room was indicted Tuesday on federal charges that include possession of a biological toxin.

Roger Bergendorff and his lawyer, Paul Riddle, did not appear when U.S. District Court Magistrate Peggy Leen unsealed the indictment and scheduled Bergendorff for an arraignment and plea May 2, federal prosecutor Gregory Damm said.

Damm declined to comment further. Riddle said the indictment was not a surprise and that Bergendorff would plead innocent.
