Use of undercover informants in jail cell amounted to a custodial interrogation and violated Miranda
People v. Zapata (Cal. Ct. App., Feb. 10, 2026, No. D084024) 2026 WL 366837, at *1
Summary: A “Perkins operation” is when an undercover operative is placed in a cell with the suspect to obtain information from the suspect. The term derives its name from Illinois v. Perkins (1990) 496 U.S. 292, 110 S.Ct. 2394, 110 L.Ed.2d 243 (Perkins).
During a Perkins operation, Zapata admitted to two undercover officers that he murdered Justin Triplett. A jury who heard a recording of Zapata’s confession convicted Zapata of second degree murder. On appeal, Zapata argues the trial court’s admission of his statements violated Miranda because he had invoked his right to an attorney, he did not waive that right when he spoke with the undercover agents, and the involvement of a known law enforcement officer transformed the operation into a custodial interrogation. The Court of Appeal agreed.
