FEBRUARY 18--The man suspected of intentionally crashing an airplane into a Texas office building today appears to have posted a lengthy online diatribe attacking the Internal Revenue Service and declaring that, "I know I'm hardly the first one to decide I have had all I can stand."

The six-page manifesto, which you'll find here, is dated "2/18/10" and is signed "Joe Stack (1956-2010)." Andrew Joseph Stack, 53, has been identified as the man who flew a small plane into an Austin building housing IRS offices. The statement was uploaded to the front page of a web site that was registered in 2003 by a Joe Stack, who listed an address in San Marcos, Texas, which is about 35 miles south of Austin.

The online posting is titled "Well Mr. Big Brother IRS man... take my pound of flesh and sleep well." Cached versions of Stack's web site, which described his software development consulting business, noted that he founded the firm in southern California in 1983, and eventually relocated to the Austin area to "lend a hand to the growing high technology industry in South-Central Texas." Stack, who has played bass in an Austin band, is pictured at left.

Alex Melen, whose firm hosts Stack's site, told TSG that Stack last changed his web site this morning at 10:12 AM (Eastern). His Piper Cherokee crashed into the Austin building at around 11:00 AM (Eastern). Until Stack uploaded his suicide note, his site consisted of a handful of pages describing his business, Embedded Art, and its history. A screen grab of the previous front page of Stack's site, which he backed up Tuesday afternoon, can be seen here.

Melen said that Stack paid his annual hosting fee with a credit card, and last year changed his billing address from San Marcos to an address on North MoPac Expressway in Austin.

Prior to speaking with TSG, Melen said he had been contacted by FBI agents in Austin and New Jersey, where his hosting business is located. At 2:40 PM today, Melen deleted Stack's web site at embeddedart.com. He replaced it with a statement noting that, "This web site has been taken offline due to the sensitive nature of the events that transpired in Texas this morning and in compliance with a request from the FBI."
