True crime is a type of storytelling that talks about real-life crimes that have happened in the past. These stories can be scary and some of them can be really sad.
Think of it like playing cops and robbers with your friends, but instead of making the story up, you learn about things that really happened. You might hear about someone who stole something from a store, or someone who hurt someone else on purpose.
True crime stories can help us understand how and why people do bad things. It can also teach us how to be safe and make good choices. However, it is important to remember that these are real-life events and people were hurt, so we should always be respectful and not glorify or celebrate the crime.
