Okay kiddo, sometimes when someone goes to jail they may feel very sad, scared or alone. These feelings can be really big and overwhelming, and sometimes the person might not know how to deal with them in a healthy way.
Sadly, sometimes a person may try to hurt themselves because they feel like they can't handle those feelings anymore. This is called "prisoner suicide". It means that somebody who was in jail killed themselves, and it is a really serious thing.
It's important for people who work in the jail (like the guards and doctors) to make sure that prisoners don't feel so bad that they would try to hurt themselves. This means treating them with kindness, making sure they have access to things like counseling if they need it, and keeping a close eye on them to make sure they are safe.
Everybody deserves to be treated with respect and care, even when they have made mistakes. It's important to remember that people in jail are still human beings, and they deserve to be treated with dignity, even if they are being punished for doing something wrong.
