When someone thinks of a serial killer, they probably imagine some sort of knife-wielding maniac doing his dirty work in the dead of night, silencing the screams of the innocent for the his sick pleasure. Just looking at him tells you he's crazy. However, Lydia Sherman was the opposite of all that. The Poison Queen managed to kill all 3 of her husbands and seven of their children in broad daylight with nothing more than a little arsenic. Maybe she was crazy, but maybe she had reasons to kill those people. Lydia Sherman, the arch-assassin of Connecticut, has a story that may be difficult to understand, but should be known. There have been many people who kill with poison and from all different eras. In 2012, a woman named Deborah Cain was drinking her husband's morning cup of coffee when she noticed something strange: It appeared to be colored green. Suspicious of this strange coloring, Cain immediately called the police. After a police investigation, rat poison was discovered at the bottom of the coffee pot. The whole case was full of suspicion; Usually the woman's husband did not make her coffee. William Cain claimed that he had not tried to do anything that might make her ill, but Deborah confirmed that a friend had warned her that he would kill her. William Cain was arrested and tried on Wednesday, May 16, 2012. Long ago in ancient Rome there was a woman named Locusta who was considered Rome's professional poisoner. She was employed by Agrippina the Younger, the last wife of Emperor Claudius. He wanted him dead, so he gave the job to Locusta. Locust managed to kill him by serving him a plate of poisoned mush... in the middle of a sheet of paper... that Lydia Sherman was guilty of all charges. Connecticut at the time did not allow women to be hanged, so she was sentenced to life in prison, where she died at the age of 54. Lydia Sherman was a mysterious assassin, and even after her misdeeds she is still relevant. I found it interesting that Sherman killed the people he was supposed to love the most: his family. I don't think, however, that the world would be better without her. All life is sacred and we can learn from its mistakes. It might leave a bad taste in the mouths of those who know it, but it's still important. Without people like her in the past, people today would have no morals, as there would be nothing to stand on. The Poison Demon was a strange, perhaps problematic person, and I hope that after the things he did we can be wise enough to know that they shouldn't happen again..
