The Sentox Project was a project by Omicron International to create a military-grade nerve gas called Sentox for the Department of Defense. The head scientist on this project was Alan Burkett, who was assisted by Michael Gravel and others. Christopher Henderson, the Senior Vice President of Research and Development of Omicron, had access to this project. Most of the gas was decommissioned and destroyed by the government, but a number of canisters were smuggled by the perpetrators of the Sentox nerve gas conspiracy. To cover the theft, Burkett, Gravel, and at least one other scientist were covertly murdered by Henderson and the conspirators. The murders were done in relatively close succession but successfully framed as accidents, such as helicopter and car crashes, and a drowning on a diving trip.
