Rachel Ann Niemeyer, Petitioner: v. the People of the State of Colorado, Respondent:

Summary

The court held that Niemeyer was in custody for purposes of the Fifth Amendment when police interrogated her at the station without first providing warnings. Considering the totality of the circumstances, the court emphasized the late-night station interrogation, her isolation, physical restraints, restricted movement, lack of transportation, and repeated requests to visit her seriously injured husband. The court further held that admitting her unwarned statements was not harmless beyond a reasonable doubt because those statements formed the foundation of the prosecution's case.
