“A man” (that’s how the media are identifying him right now) is comatose and in critical condition in Las Vegas, and presumptive tests indicate that a substance found in his hotel room is the deadly poison ricin.

(CNN) — A man who stayed in a Las Vegas hotel room where ricin was found is in critical condition at a hospital, where he has been since February 14, said Kathy Suey, deputy chief of the Las Vegas Metropolitan Police Department.

Suey said the man called for medical help on February 14, saying he was suffering from respiratory distress, and was transported to the hospital.

A friend or relative of his who came to remove his belongings from the room found the ricin on Thursday, she said.
