For each type of murderer there are motives that provoke them to kill their victims, part of the reason of why they do it is because they are not mentally ill, but seek revenge. “Andrew Kehoe was a farmer living in Bath, Michigan. A member of the school board and the town clerk, on May 18, 1927 he orchestrated a plot to dynamite the Bath Consolidated School, killing thirty-seven children”(“Andrew Kehoe ”). The motive that made Andrew do this was revenge. The reason was because tax collectors were going to foreclose on his farm. There are more murderers that killed for revenge like George Jo Hannard in Killen, Texas. George shot people inside of a cafeteria, and Adam Lanza and the Sandy Hook shooting took place in an elementary school. Michael
