My thoughts exactly; I realized that after posting my comment, too. All it would take is for mom to put two-and-two together with the circumstances to get suspicious. It’s possible there are other relatives with keys, though. It’s also possible there isn’t any footage available of the actual entering of the property. Still pretty screwed unless everyone else is as dumb as he is. Cops will probably have asked the aunt if anyone else has a key or otherwise had free access, since there’d be no sign of forced entry, which would greatly narrow down suspects no matter how many relatives had keys. If her nephew happens to appear on camera nearby right around when the robbery could have occurred, and he’s not routinely seen walking around the neighborhood, that’s not a good look. It’s still circumstantial, though. With 4chan in mind again, he probably does still live with his mom and has the stolen stuff in his closet or under his bed or something. Even if he doesn’t still live with her, I bet his mom could still make an excuse to visit his place to look around. Then he’s really cooked once she finds the stuff. It’s probably only a matter of time before it all blows up in his face. Something tells me OOP isn’t exactly a criminal mastermind.
