They found Shin at his parents' house, hiding in a closet. Once caught, Shin reacted violently to the arrest, hitting one officer in the nose.
Before being taken in, though, he called a local newspaper, the Argus, and complained that the media was portraying him as a "Jacko wacko." (He also admitted he was in Gavin's apartment building, but refused to comment further on the situation, saying, "What happened that night is between me, the doorman, and Gavin.")
The Argus also confirmed that -- the rumors you've heard are true -- the composite picture of Shin with Gavin featured "an Asian man wearing only a diaper." Probably an astronaut.
