The principal issue on these appeals is the propriety of the trial court’s ruling excluding expert testimony on the potential for inaccuracy of eyewitness identification of participants in crimes. After a joint jury trial, the defendants, Harold Kemp and his brother Robert Kemp, were found guilty of four counts of robbery in the first degree in violation of General Statutes § 53a-134 (a) (2). Harold Kemp was given an effective sentence of five to ten years imprisonment and Robert a sentence of six to twelve years. They have separately appealed their convictions.
The jury could reasonably have found the following facts. On January 31, 1980, between 7:30 and 8 p.m., three black males entered Jimmy’s Army and Navy Surplus Store in West Haven and robbed the owner and his employees at gunpoint. The first man to enter the store, later identified as the defendant Harold Kemp, was unarmed but took some leather jackets and money from the cash register. The second man, later identified as the defendant Robert Kemp, carried a shotgun and took personal property from three of the employees. A third male, David Tyson,
The defendants claimed that this was a case of mistaken identity and presented an alibi defense. At trial, to support their argument that the state’s witnesses were mistaken, they sought to call as an expert witness, Robert Buckhout, a psychologist and recognized authority on the factors which affect the accuracy of identifications. The defendants offered his testimony to impeach the reliability of the witnesses who identified them. Through Buckhout, they sought to explain to the jury that: “(1) stress, particularly stress during an incident involving violence by a weapon, may decrease the reliability of the identification; (2) memory is not a ‘recording’ device which accurately records an event and does not change over time; (3) the identification process is affected by post-event information learned by a witness; (4) and the level of certainty demonstrated by a person does not reflect a corresponding level of accuracy.” After an evidentiary hearing was held outside the presence of the jury, the trial court refused the defendants’ offer to introduce the expert testimony.
On appeal, the defendants do not directly attack the reliability of the identifications made, but claim that the trial court erred in excluding Buckhout’s testimony. They argue that the court abused its discretion and vio
The trial court has wide discretion in ruling on the qualification of expert witnesses and the admissibility of their opinions. State v. Girolamo,
Although we have never specifically addressed the issue of the admissibility of expert testimony on the reliability of eyewitness identifications, the issue has received increased attention in other courts in recent years. Almost uniformly, state and federal courts have upheld the trial court’s exercise of discretion to exclude such testimony. See, e.g., United States v. Purham,
The defendants claim that Buckhout should have been permitted to explain that a witness’ expression of certainty does not make the identification more reliable, and that stress, the passage of time and intervening events diminish a witness’ ability to make an accurate identification. Matters such as these, however, have generally been found to be within the realm of common experience and can be evaluated without expert assistance. United States v. Amaral, supra, 1153; People v. Clark, supra, 21; Commonwealth v. Francis, supra, 100-101; People v. Brown,
We are aware that in many cases the determination of guilt or innocence depends in large part on the credibility assigned to eyewitness identifications, and that in many instances identifications may be unreliable. See United States v. Wade,
We also reject the defendants’ contention that the exclusion of the expert testimony abridged their sixth amendment right to call witnesses in their defense. This right does not grant the defendants the freedom to call any witness they choose. “In the exercise of this right, the accused, as required of the State, must comply with the established rules of procedure and evidence designed to assure both fairness and reliability in the ascertainment of guilt and innocence.” Chambers v. Mississippi,
The defendant Harold Kemp also claims that the jury should have been instructed on the elements necessary
As noted above, the jury could reasonably have found that Harold Kemp was unarmed at the time of the robbery and that he took money and leather goods from the store while his brother robbed the employees with a shotgun and Tyson shot the owner with a pistol. Harold Kemp’s argument that he was entitled to a charge on accessorial liability is premised on the contention that he could not have been convicted as a principal to robbery in the first degree under General Statutes § 53a-134 (a) (2) because he did not have a gun.
There is no error in each case.
In this opinion the other judges concurred.
Notes
David Tyson, not a party to these appeals, pleaded guilty to robbery charges arising out of the incident.
Perric Isenstein, another employee of the clothing store, also identified both defendants. He was, however, unable to testify at trial.
In its charge to the jury, the court emphasized the critical nature of the identifications and reviewed various factors which might affect their reliability, including delay, performance under stress and inaccuracy of prior descriptions.
“[T]here is no practical significance in being labeled an ‘accessory’ or a ‘principal’ for the purpose of determining criminal responsibility.” State v. Harris,
General Statutes § 53a-8 provides: “A person, acting with the mental state required for commission of an offense, who solicits, requests, commands, importunes or intentionally aids another person to engage in conduct which constitutes an offense shall be criminally liable for such conduct and may be prosecuted and punished as if he were the principal offender. ’ ’
