In State v. Cepeda, 51 Conn. App. 409, 723 A.2d 331, cert. denied, 248 Conn. 912, 732 A.2d 180 (1999),, the court excluded as irrelevant the testimony of a witness that the victim's brother had stabbed the defendant's brother during a melee involving at least six men. The court explained that such testimony did not implicate the defendant or the victim and was not connected to the "crucial issue" of whether the defendant shot the victim. Id., 418.
