CENTENNIAL, Colo. – A threatening letter containing an unidentified white powder was sent to a John McCain campaign office in this south Denver suburb Thursday, authorities said. No injuries were immediately reported. Authorities later said the substance was not hazardous.
A second letter sent to a McCain campaign office in New Hampshire initially was reported to contain threatening language and white powder. Authorities said that was a false alarm and there was no powder in that envelope.
At least 19 people were examined at hospitals or were quarantined outside the Colorado office while authorities tried to determine whether the powder was hazardous. Everyone was sent home by late Thursday, said Arapahoe County Sheriff Grayson Robinson. He said the substance was not hazardous, but that it will take days to determine what it was.
Andy Lyon of Parker South Metro Fire Rescue Authority said the return address on the envelope listed the Arapahoe Detention Center and the name of an inmate.
Sheriff’s officials said the inmate suspected of sending the letter is Marc Harold Ramsey, 39, who has been incarcerated since September 2007 on investigation of felony menacing, harassment and second-degree assault on a peace officer. Ramsey may face federal felony charges for Thursday’s incident, sheriff’s officials said.
Lyon said the first line of the letter used threatening language. He refused to give any details.
Malcolm Wiley, a Secret Service spokesman in Colorado, said there was no powder in the New Hampshire envelope. He said he did not know about the content of the letter, which had a Denver return address. That alarmed staffers in Manchester, who had heard about the Colorado incident.
