The defense placed his so called mistress on the stand......it’s up to the jury to determine who is the liar. Same with Cindy and Casey.
BS, that Fact that Casey is a liar has been stipulated by the defense and it is, in fact, a part of the defense. The Fact that Cindy lied has been documented by evidence provided by her employer. The jury could ignore the facts but they are facts.
Whether or not George had a mistress (no facts supporting this BTW) has nothing to do with the case against Casey, it's just defense chaff in an attempt to confuse facts.
