Errors in Defendant's third jury trial, individually and cumulatively, prejudiced outcome of trial, in which evidence was closely balanced, and ultimate issue involved credibility of the two versions of events of night in question, where Defendant claimed that victim committed suicide. Allowing police detective to testify that he never believed that the defendant told him the truth on the night in question was error, especially as police officer is a figure of authority whose testimony would likely be credited more weight by jury.
