The Washington Post is reporting that ^The Documents contained a fax header indicating that they were faxed to CBS from a Kinko's in Abilene, Texas.

Documents allegedly written by a deceased officer that raised questions about President Bush's service with the Texas Air National Guard bore markings showing they had been faxed to CBS News from a Kinko's copy shop in Abilene, Tex., according to another former Guard officer who was shown the records by the network.

The markings provide one piece of evidence suggesting a source for the documents, whose authenticity has been hotly disputed since CBS aired them in a "60 Minutes" broadcast Sept. 8. The network has declined to name the person who provided them, saying the source was confidential, or to explain how the documents came to light after more than three decades.

There is only one Kinko's in Abilene, and it is 21 miles from the Baird, Tex., home of retired Texas National Guard officer Bill Burkett, who has been named by several news outlets as a possible source for the documents.

Robert Strong, who was one of three people interviewed by "60 minutes," said he was shown copies of the documents by CBS anchor Dan Rather and producer Mary Mapes on Sept. 5, three days before the broadcast. He said at least one of the documents bore a faxed header indicating it had been sent from a Kinko's in Abilene.

--Update!--
Kevin McCullough of Crosswalk.com has spoken with the Abilene Kinko's. It was confirmed that Burkett has a standing account there and that he was there last week. It's looking more and more like Burkett's a/the source.

--Addendum--
So, how long do you figure it'll be before we get our first "Rove gave ^The Documents to Burkett" or "Rove sent someone to Abilene to frame Burkett" conspiracy theory?

--Update--
NRO's Kerry Spot points out that Killian's secretary thinks the wording used in ^The Documents sounds more like Army wording and that Burkett spent 28 years in the Army National Guard.

Marion Carr Knox, the secretary to Col. Jerry Killian, President Bush's National Guard commander, this evening, during her interview with Dan Rather:

"And there are words in there that belong in the Army, not to the Air Guard. We never used those terms."

From the Veterans for Peace web site:

Lt. Col. Bill Burkett completed 28 years of decorated service and was medically retired from the US Army National Guard in 1998.
