As Rivera's civil lawyers try to prove he was railroaded, the authorities who won Rivera's convictions face questions about the case they built. Charles Fagan, an investigator who helped obtain Rivera's confessions, said during a sworn deposition in October he remembered little about the episode with the shoes. Fagan, who served as undersheriff of Lake County before retiring in 2011, said he did not plant the evidence on the shoes and did not know of anyone else doing so, according to a copy of the deposition.
