But if you were in a situation in which a lunatic had invaded your house, wouldn't you say, "gee, I don't have much cash -- here's everything I have -- here's also some jewelry, some paintings, and there are at least a million dollars worth of cars in the garage. The keys are on hooks down there. Here's my ATM card, here's the code, here are some credit cards. Help yourself." Seems like you would want to avoid a sleepover with the guy.
Sounds like the perp specifically wanted cash.
