Larry Fiato was a government informant who, along with his brother Craig, delivered significant testimony against the prosecution's own credibility. Called by defense attorney Robert Shapiro, Fiato testified that Detective Vannatter's sworn claim — that Simpson was not a suspect when detectives went to Rockingham — was contradicted by what Vannatter had said privately, a revelation bolstered by corroborating testimony from FBI agent Michael Wacks. The sensitivity of Fiato's status as an informant was underscored by Judge Ito's extraordinary step of excluding all photographers and sketch artists from the courtroom before he took the stand.
