That's very plausible. Right now, the big shed in our backyard contains mine and my partner's furniture, whitegoods, and random other things like cookware just in case this living with my mother thing goes wrong. We are disabled, and we would never be able to afford to replace it all. I also know there are boxes of my late grandmother's stuff piled up in the garage that one day, I am going to have to deal with. It's not sentimental stuff, it's random things, like shoes and soft furnishings, but at the time the house was being cleared, there was no time to sort it, and now they're just a problem for Future Me to deal with. Eventually.
You will be happy to hear we have no murder trophies, though. Just a lot of books about it.
