Around 3 a.m. on August 15, 2008, the Nashua, New Hampshire Police Department received a call reporting that an African-American male was trying to break into cars parked in the lot of the caller’s apartment building. When an officer responding to the call asked eyewitness Nubia Blandon to describe the man, Blandon pointed to her kitchen window and said the man she saw breaking into the car was standing in the parking lot, next to a police officer. Petitioner Barion Perry’s arrest followed this identification.
Before trial, Perry moved to suppress Blandon’s identification on the ground that admitting it at trial would violate due process. The New Hampshire trial court denied the motion. To determine whether due process prohibits the introduction of an out-of-court identification at trial, the Superior Court said, this Court’s decisions instruct a twostep inquiry: The trial court must first decide whether the police used an unnecessarily suggestive identification procedure; if they did, the court must next consider whether that procedure so tainted the resulting identification as to render it unreliable and thus inadmissible. Perry’s challenge, the court found, failed at step one, for Blandon’s identification did not result from an unnecessarily suggestive procedure employed by the police. A jury subsequently convicted Perry of theft by unauthorized taking.
