Making assumptions without looking at it from every side is a pretty big mistake to make. I'm not saying there's always a solution or it isn't the simplest one but people are complex and have complex reasons for doing what they're doing.

Why would someone only take the rings? It's such a strange thing to only steal that. Continuing to be curious and explore the rational behind another person. Sometimes things are senseless but often they aren't... Lots of people struggle through this world and do terrible things because they feel they have no choice. That's no excuse, of course, but something to keep in mind.

And desperation is a remarkably easy path to track in solving a case.
