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. 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. 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.
