Heriberto Seda is a person who did a very bad thing a long time ago. He hurt and killed people. He was what we call a "serial killer," which means he did this kind of thing more than one time. He hurt people who lived in New York City where he also lived.
Heriberto did not have a good life. Sometimes when people don't have a good life, they do bad things. This is what happened to Heriberto. He was not happy and he did not know how to make things better. Instead, he hurt people.
Luckily, the police were able to catch him and he was put in jail. He will not be able to hurt anyone else. It is important to remember that we should always be kind to one another, even when things are hard.
