Answer 1

Set in Washington, DC, Suspect centers on three disparate characters. Carl Wayne Anderson is a homeless, deaf Vietnam vet accused of murdering a federal judge's secretary, and Kathleen Riley is the beleaguered public defender assigned to his case. An agribusiness lobbyist who normally works on Capitol Hill, Eddie Sanger is made a member of the jury and begins investigating the details of the murder himself, eventually teaming up with Riley to solve the case.

Noted for something of a deus ex machina ending, the film's climactic scene (in which the actual murderer is revealed) was panned by Roger Ebert, whose review noted that it is "as if an Agatha Christie novel evaluated six suspects in a British country house, and then in the last chapter we discover the killer was a guy from next door."

All I could find, hope it helps.
