Sometimes people just get fed up. 66 year old Maria Lauro was let go from four different elementary schools in Florida for poor performance. After being fired from her last gig, Maria decided it would be a good idea to send her former employers a little package in the mail. The packages contained an unknown white powder and notes indicating they were "punishment" for letting her go. All the letters were sent to those involved in her performance review and termination. Maria plead guilty last week, and said that she wanted the victims to believe they had been exposed to a deadly biological toxin that turned out to be just plain baking soda.
