Investigating WHO

You have a suspect, WHO has likely committed a crime. 

What might you want to know about him or her? I have compiled the list below - if you have more to add, let me know by commenting below.

Keep in mind the list does not indicate you need to research the suspect to this level, but in various cases you want relevant information about the suspect. These lists can help you think of what is required in an investigation of a clearly identified suspect, in a case that is officially opened for investigation.

Ask yourself: is this information available to me? is this information relevant to the investigations?

If the information is relevant but not available, find out how you might obtain it.
