In 1999, a 20-year-old boy named Paul Warner Powell was obsessed with a 16-year-old girl but she wasn't into him.
Frustrated he breaks into her house and demands that she dates him, when she refuses, he kills her and then he kills her 14-year-old sister too, or so he thought. The younger sister survived and easily identified Paul as the killer.
Paul showed no remorse in court and even called the victim stupid.
When he was sentenced to death though, his attitude changed and he begged and cried for mercy.
Unfortunately, mercy came in the form of a legal loophole that switched his death sentence to life sentence.
Believing he was safe from the death penalty because of double jeopardy, he wrote a ridiculous letter to the prosecuting attorney, basically admitting to every single detail of the crime. Kind of bragging about what he got away with.
The attorney took the letter and gave it to the judge. The judge looked at it and said, “we have new evidences here" and ordered a new trial and immediately Paul was resentenced to death.
A few months later the low-life was executed.
