It was all the rave in Seattle:
One young man told Seattle police detectives that he invited Kyle Huff to his after-hours party because he was "sketchy" and gave off "bad vibes" -- and he thought it would be entertaining to have someone like that at his house.
Another resident of the Capitol Hill house told police that he later heard loud bangs and screams outside, peeked through the blinds and saw Huff, shotgun at his hip, blasting rounds into the front door with "a look of contentment on his face -- almost a smile as he fired."
Search warrant documents filed Tuesday in King County District Court in Seattle laid out new details of Huff's rampage Saturday, which left seven people dead, including himself. Two others were wounded.
