Well, now I’m thinking there is no baby involved, except “Boo Boo” Niles himself. When his mother said “his child,” she was referring to Mr. Scott’s daughter. The implication is that Mr. Niles was on the side of Mr. Scott’s daughter in whatever dispute was going on.
Now I’m thinking this story is so strange we may never know what really happened only that a 17 year old was shot.
