4. Evidence: Evidence is any information or material that can be used to establish facts in a legal investigation. It can include physical items like weapons, clothing, or documents, as well as testimony from witnesses.

5. Witness: A witness is someone who has observed an event and can provide information about it. Witness testimony is often crucial in building a case and understanding the sequence of events.

6. Interrogation: Interrogation is the process of questioning individuals, such as suspects or witnesses, to gather information relevant to an investigation. Detectives use various techniques to elicit truthful and accurate responses.
