One of the first places to look is for the person's social media presence - this will help you identify basic information about age, education, work experience, and what the person values through shared posts.
Be aware, however, that this is how the person wants to be portrayed; it is their public face to the world. You will want to explore other sources to understand their impact in their line or work or community involvement.
Don't forget to look for local newspapers. Search directories like this one at refdesk.com to find major county/city newspapers: refdesk.com Indiana Newspapers. Or, go to the county that your individual is from or works in, and search for a local newsletter or paper.
Search the local news broadcast media for information on your individual.
