"We have people responding," said Special Agent Malcolm Wiley. "We have no reports that anyone has been hurt."
MORE SODIUM CYANIDE SHOWING UP, LIKE WHAT THE SOMALI HAD IN THE DENVER HOTEL ? August 15th 2008, Terror Probe in Case of Somali-Born Man Found Dead of Cyanide Poisoning in Denver Hotel ....FBI terrorism experts are investigating whether the death of Somali-born Canadian citizen, Saleman Abdirahman Dirie, whose body was found Monday in a Denver hotel room with about a pound of extremely toxic sodium cyanide — is connected to the upcoming Democratic National Convention."I don't see how anybody could do anything but look into the possibility that this is a potential terrorist attack," Dr. Andrew Ternay told CBS 4 News in Denver.
Authorities also say a similar letter was sent to a McCain office in Manchester, N.H. where police and fire department personnel responded to the scene.
It wasn't immediately known whether the New Hampshire letter also contained a powder, said Jeff Sadosky, a spokesman with McCain's national campaign office in Arlington, Va.
In Colorado, Andy Lyons with South Metro Fire said the building in the 6300 block of South Racine Circle has been evacuated and that a Hazmat team has gone into the offices to try to determine what the powder might be.
A spokesman for the McCain campaign said an employee at the Centennial office opened an envelope containing a threatening letter and an unknown amount of powder at about 3 p.m.
"The campaign immediately notified local and federal law-enforcement authorities, evacuated the office and our staff is taking all necessary precautions and is being looked at by health care professionals," said Jeff Sadosky, a spokesman at the McCain campaign's national headquarters in Virginia.
Sadosky did not have any word on the condition of the employees. He estimated that somewhere between five and 10 people were in the office at the time. Lyons said he didn't know the size of the envelope or whether the mail was addressed specifically to McCain.
"Our guys did not find any powder. There were maybe a couple of grains of something inside an envelope and they had to kind of work to get a sample," Lyon said. Seven people drove themselves to Sky Ridge Medical Center, but none showed any symptoms of exposure to a toxic substance, hospital spokeswoman Linda Watson to the Associated Press.
Lyons said 12 people were quarantined outside the Colorado office, including three police officers, two firefighters and seven civilians. The threat comes four days before the opening of the Democratic National Convention in Denver.
