Since you are asking me, I'm replying about me (not MM): If I think there is something important on my missing relative's computer that I want to see/access but don't want the LE see/know, I would get hold of the computer before it gets to the LE's hands. If I simply want to know about credit card/bank withdrawal info, I'd contact the credit card company or the bank, because I would think my behavior would look sneaky and suspicious if I take my missing relative's computer when they have just vanished without an explanation and before the LE has investigated/processed everything in the house. If I suspect foul play, I'd definitely let the LE do their work before I take anything away. If I believe they went on vacation, then I wouldn't take their computer, as it's not mine.
