Investigation continues into suicide attack in Austin

– Federal law enforcement officials are closely examining an anti-government message on the web linked to the software engineer who slammed his small plane into an Austin office building.

Authorities say A. Joseph Stack III launched a suicide attack on the agency Thursday. The crash set off a raging fire that sent workers running for their lives. Two bodies were found in the wreckage yesterday. Officials wouldn't say whether either of them was the pilot.

The Internet posting by Stack expresses his anger at the government, specifically the Internal Revenue Service.

Gov. Rick Perry said the crash shows risk of having a free society.
