Yes, it's dead. No, I didn't kill it. I found it dead on the floor, and I put it on the washer until I could take a picture. Then I scared the bejeebus out of myself every time I walked by it.
I think it's a huntsman? Scary looking, and I know there's several of these HUGE spiders in the house. I usually leave them alone. I'm not sure what killed this one.
