State v. Kelly
In State v. Kelly, 256 Conn. 23, 40-41, 770 A.2d 908 (2001), two sets of two witnesses, the victim's parents and the investigating police officers, were permitted to testify about the statements the victim had made to each set of witnesses.
The Court concluded that the Kelly defendant had failed to show that the testimony of both of the police officers and both of the victim's parents was likely to have affected the outcome of the trial. Id., at 39. The testimony was corroborative and merely cumulative, and was therefore harmless. Id., at 39-40.
