Police: Deadly toxin found at Las Vegas hotel

Police in Las Vegas, Nevada, are investigating the discovery of what they said is the deadly poison ricin in a hotel room.
Preliminary tests show the substance is ricin, authorities said, but other tests to confirm it are under way.
Meanwhile, the reason the substance was in the room remains a mystery.
"We don't know who [the ricin] belongs to or why it would be here at this time," said Capt. Joe Lombardo of the Las Vegas Metropolitan Police Department.
The FBI, which is assisting in the case, said it saw no link to terrorism, according to spokesman Richard Kolko.
Authorities were called to an Extended Stay America hotel around 3 p.m. PT Thursday after a man brought a bag with a small container to the manager's office. The man said he found it while retrieving items from a hotel room.
The substance is "100 percent ricin," Lombardo said.
Three hotel employees and a fourth person who came to the room to retrieve some items went to the hospital as a precaution, Officer Ramon Dendy said. Three police officers who entered the room also are under watch at the hospital. All have been decontaminated, and none of the seven have shown symptoms of ricin poisoning, which can include anything from difficulty breathing, fever, cough, nausea and sweating to severe vomiting and dehydration.
