You are looking for the Xboxlivegamer.xml file, which contains information that may be relevant to your case. Also, since Xbox is a gaming platform and many people use it only for leisure purposes, it is one location a user may have overlooked if they have taken anti-forensic measures.

Since the vast majority of the files we will be looking at are .xml files, you do not need any extra forensic software to access the data. However, most well-known softwares, such as FTK, EnCase and so on, will be able to examine the files and their metadata.
