They wrote the book using sheriffs office reports, written statements from witnesses, photos from the scene of Gerwings suicide and interviews with key figures in the case, including Bromage, Tanner, lead investigator Angela Viens, Gerwings brother Fred, co-workers of the Calverts, and Gerwings longtime but then-estranged girlfriend Nancy Barry, who was living in his million-dollar Wilmot Avenue home in Columbia.
The book goes into great detail about the facts of the case and explores the plausibility of popular theories on the whys, the whos and the wheres.
