The investigation of the Elizabeth Smart abduction serves as a notable instance of law enforcement avoiding the corruption of an eyewitness's memory. When 14-year-old Elizabeth was abducted, her 9-year-old sister was the sole eyewitness. Police and the FBI proceeded cautiously without showing her line-ups or composite sketches to prevent implanting false memories. Months later, the sister accurately recalled the abductor's voice from a prior encounter, leading to his capture and Elizabeth's safe return.
