Colorado v. Connelly

Francis Connelly (defendant), who suffered chronic schizophrenia and had gone off his medication, spontaneously confessed to murder to a police officer, was given Miranda warnings, and continued confessing and leading police to the crime scene while appearing competent to officers; the next day he became confused, claiming voices told him to confess, and was later found incompetent to aid his defense before regaining competence. A psychiatrist testified his mental illness impeded his free will, and the trial court suppressed the confession as involuntary, affirmed by the Colorado Supreme Court.
