If there was alot of valuable items left untouched the first time, then they may be coming back soon... This has happened to me, took only the small stuff they could carry in a bag the first time, came back about 2 weeks later and had cleaned us out, luckily I came home early that day and when I opened the front door, they took off through the back and all of our stuff was left in a huge pile at the back door before they could get it out....appearently they had a vehicle parked out back in some apartments behind us at the time. I was young in middle school back then...today would be a different story as both my wife and I have a CHL and carry at all times.
