A letter each have been sent to the admiral, secretary of defense and the president of the United States of America. Each one of them was laced with castor oil, a strong and easy to make poison. We do not know the sender of the letters, nor do we know his, her or their motivations. It is not the first time when someone tried to kill the president of the United States with a letter; even Barack Obama received such mail. All the earlier attempts at this method of killing was unsuccessful, foiled by the special team of men selected to carefully examine every letter coming to either the White House or Pentagon.

Better luck next time.
