> In 1994, Burson-Marsteller executive Thomas J. Mosser was killed after opening a mail bomb sent to his home in New Jersey. In a letter to The New York Times, Kaczynski wrote he had sent the bomb because of Mosser's work repairing the public image of Exxon after the Exxon Valdez oil spill.
This Netflix documentary on the Unabomber was pretty interesting; there are other sources I'm sure, but this seemed good. His participation in a multi-year Harvard psychology study was a fascinating facet to the story and his development.
