Circumstances of Death
During the early morning hours, Special Agent McDonald accompanied by other agents and a Florida state revenue agent, were preparing to raid a moonshine still hidden deep within the swamps near Tampa, Florida. To reach the distillery without being seen, the agents waded through knee deep water and saw-grass.
However, just prior to the raid, and while still in the water, Agent McDonald suffered a fatal heart attack. A medical examination later revealed that the heart attack was aggravated by the exertion required to reach the still.
