Smith’s 18-year-old brother, Devin Smith, was shot multiple times in the head, according to the document.Kaylor and his wife, Kaylie Kaylor, told investigators that they were upset because Devin Smith had masturbated in front of his bedroom window in full view of the Kaylors' young daughters several days earlier.
