Gary Webb, revisited?

Gary Webb, revisited? Environmental investigative reporter Kevin Carmody is suicided. Is this reporting on Barton Springs Pool in Austin, Texas really what it was about? Or was he working on something that might cost somebody some money? I can't think of a more dangerous job than an investigative reporter working on environmental issues. Do you think anyone will notice when the last investigative reporter in the country commits 'suicide'? The list is getting a bit long.
