John David Roy Atchison was a man who did some very bad things. He was a lawyer who helped people with legal stuff, but instead of being good, he did bad things to kids.
You see, some grown-ups like to hurt kids, and it's not okay. Atchison was one of those people. He did bad things to kids, and he was caught by the police.
After he was caught, he knew he was in trouble, so he did something even worse. He took his life, which means he died.
The police and many people were very sad about what he did, both to the kids and to himself. It's important to remember that hurting people is never okay, and if someone hurts you, you should tell a trusted grown-up.
