Just passing down some wisdom, in case you know then great, if case you don't than hopefully you'll find it useful;
Something that I learned from a Phoenix Wright gameplay actually, but if you're stuck in a information because it doesn't appear to fit anywhere, or you can't think of an information that fits, try changing your line of questioning.
If you can't find a motive for X person to do something for example, change the question from "Why did they chose to do this?" To "Why did they had to do this?"
You don't have to do this all the time, but you could try it the next time you get stuck on an information, especially if it's a question; try changing the question itself.
Most often than not it might lead to possibilities that can be easily debunked, but even that can be useful. I sure hope it's helpful \( \)
