This was a serious investigation, involving police in S. Dakota questioning someone about a crime committed in Alaska. Across state lines, so not a shoplifting case on might assume.The difference between being a friend, boyfriend, or coworker and being a spouse is that marriage grants someone 'marital confidence privilege', meaning they can refuse to testify about certain things. I assume you can see why then, her being married to what I assume is an alleged felon sort of might be considered a 'pertinent detail'.
