Paul Warner Powell killed a 16-year-old girl because he was angry she had a black boyfriend. He then waited for her sister to come home and also attacked her, but she survived. Powell was arrested and convicted of capital murder. He was sentenced to death by electrocution, yet the case was eventually overturned because of insufficient evidence.
Powell, not being the sharpest tool in the shed by any means, was so proud of escaping death that he wrote a letter to the prosecutor and admitted to raping and killing the girl. After he admitted to the crime, the girl’s sister then testified against him. Fortunately, Powell gave so much detail and new evidence he was able to be tried again. He was eventually executed in 2010, the most recent man to be killed by an electric chair in the United States.
