I was looking up executions. I came across the youngest person ever to be put in the electric chair. His name was George Stinney. He was fourteen years old, and executed in 1944. He was convicted for first-degree murder in Columbia, South Carolina. People questioned his guilty conviction, because this was 1944, and African Americans were targeted for things they never committed. So, as some Americans would say is that his conviction was, "suspicious at best and a miscarriage of justice at worst." Even though George Stinney did plea guilty. Some say he wasn't.
This is the movie clip of George Stinney's execution.
They had no evidence to the murders. He was 5'2. The girls that were murdered were 5'11. There was no way he could have bashed their heads in. They had no witnesses, or anything. They just heard someone saying that he did it, and they arrested him. I believe the lawyer had said if he pled guilty then, he wouldn't get into more trouble. So, he did. He didn't realize the court would order him to the chair.
