Finding no reason to treat impermissibly suggestive events during trial preparation differently from other suggestive identification procedures, the Court extends the relevant principles in Henderson to trial preparation sessions. Witnesses who have made a prior identification should not be shown photos of the defendant during trial preparation -- neither new photos of the defendant for the first time nor, absent good reason, the same photos they previously reviewed. If a party can demonstrate a good reason to show witnesses a photo of the defendant they previously identified, the party must prepare and disclose a written record of what occurred. If, however, a witness has not previously identified a suspect, investigators can conduct an identification procedure during pretrial preparation in accordance with Henderson. A record of the procedure should be created and disclosed under Rule 3:11. Here, to determine the admissibility of the identification evidence, the Court remands to the trial court to conduct a hearing under United States v. Wade, 388 U.S. 218 (1967), and develop a more complete factual record.
