“Work related accident, I assume.”
Pretty good assumption I’d say.
Ricin has no medical uses other than cancer research,” said Captain Joseph Lombardo, head of the Homeland Security unit for Las Vegas police. “An individual citizen, other than being involved in cancer research or cancer prevention, would not have any legal means or proper means of having that.”
Dr. Nicholas J. Vogelzang, director of the Nevada Cancer Institute, said none of his researchers use the substance and nobody involved with the institute has stayed at the hotel in recent months, if ever.
“We’re not doing anything here with it,” Dr. Vogelzang said. “It’s not a currently active treatment,” he said, explaining that most cancer researchers have abandoned experimenting with ricin because it is so dangerous to people.
