An investigation is a systematic process used to gather information and uncover facts about a specific issue or event. This process often involves collecting evidence, interviewing witnesses, and analyzing data to understand what happened. Investigations can be conducted in various fields, including law enforcement, journalism, and scientific research. The goal of an investigation is to find the truth and provide clarity on a situation. For example, a police investigation may seek to solve a crime, while a journalistic investigation might aim to expose corruption. Each type of investigation follows a structured approach to ensure accuracy and reliability in the findings.
