Investigators are checking tips from the public and are working closely with the FBI and federal postal inspectors, according to police. The state crime lab is examining the letters for any evidence that could lead to a suspect, a Seattle Police Department spokesman said. Still, the investigation is proceeding on the assumption that the danger could be real, they said. Investigators have no evidence that whoever mailed the letters has the ability to make good on the threats, Seattle police said. "We are not going to be terrorized," Luying said. Utah man who knew about cousin's ricin gets probation.People in the area initially were scared after hearing about the threats, but they soon became defiant, said community activist Alison Luying, who helped organize Friday night's pub crawl. The day after CC Attle received the threat, it posted on its bar a sign reading, "Do not leave drinks unattended." The bars and their patrons have been on guard. Ricin is a poison that occurs naturally in castor beans and can be fatal if ingested or inhaled.
I expect them to die painfully while in the hospital," the letters read. "I have in my possession approximately 67 grams of ricin with which I will indiscriminately target at least five of your clients. Police say they're investigating the letters, which the bars - located in Seattle's Capitol Hill district - received Tuesday.
If you don't drink, a terrorist wins,' " Daw said. On Friday night, hundreds of locals participated in an organized pub crawl designed to support the establishments. People have flocked to the 11 bars in solidarity since the letters arrived in the mail last week, Daw and others said. The threats - letters warning that patrons would be poisoned - appear to be part of the reason business was brisk.
