Two witness lists for the ongoing Spokane City Hall investigation into the firing of former police Chief Frank Straub have shed some light into the inquiry, but the inner workings remain largely concealed from public view. The lists, which were part of a public records release sought by The Spokesman-Review, contain a total of 42 names of city employees. Straub and Monique Cotton, the police spokeswoman who made the accusation of sexual harassment against Straub that led to the continuing controversy, are absent from the list.
