What do we know about the assailant as presented in this chapter

At this point in the story, it is unsure whether the attacker is Native or White, and Bazil tells Joe that this fact is important in determining how the case will proceed. Joe visits Clemence’s house, where he spends the evening with Whitey and his grandfather, Mooshum. Much to Clemence’s silent disgust, the men begin talking about Sonja and her former career as a stripper. Joe returns home and has a disgusting meal prepared by Bazil. After dinner, he joins Cappy and Cappy’s older brother, Randall, at Randall’s sweat lodge. The sweat lodge is used for traditional Chippewa practices. While in the sweat lodge, Randall has a vision of a ghost-like figure speaking to Joe. Randall encourages Joe to speak to Mooshum about this vision.
