An investigator is a person who looks for information or facts about something in order to solve a problem or answer a question. They usually work for a company or organization, like the police or a private detective agency. They might investigate things like crimes or accidents, or they might investigate a business to make sure it is following the law. If you hear or read the word "investigator", it almost always means someone who is trying to find out something important.
