Las Vegas: The deadly toxin ricin was found in a motel room in Las Vegas on Friday, along with firearms and an "anarchist type textbook".

The room was most recently occupied by a 57-year-old man who has been in critical condition with breathing problems at a hospital for more than two weeks.

Police said there was no apparent link to terrorist activity, and no indication of any spread of the deadly substance beyond the several vials of powder found in a plastic bag in the man's room on Thursday. But what the ricin was doing there remained a mystery.

A pinprick of ricin is enough to kill.

Captain Joseph Lombardo said at a press conference that the book was tabbed at a spot with information about ricin. Lombardo did not give more information about the book or specify what kinds of weapons were found.


Seven people, including the man who found the ricin, the manager, two other motel employees and three police officers, were decontaminated at the scene and taken to hospitals for examination, but none have shown any signs of being affected by ricin.
