Just got off work and all the from the attic was on the floor. >> So you see the insulation all over the floor. What do you do next? >> I immediately looked up cuz I knew that's where it came from. Like none of this was on the floor. So I knew something was in the attic. We thought it was like a raccoon or something, but then he started screaming, "My name's Robert. My name's Robert." >> He said he lives right there. I said, "I have [music] Get your out." I never expected anything like this in this neighborhood. That's why I love cutting it. >> Right. No, that's quite a shock when you get home. >> That door right there. >> This I'm trying to come in. >> Turn around. Put your hands behind your back. >> What is underris? >> Well, for starters, I mean, you're in somebody's attic. You shouldn't be, right? The suspect was later identified as a convicted killer and police found a loaded arm hidden inside the homeowner's barbecue.
