In Culombe v. Connecticut (1961) 367 U.S. 568, the Supreme Court teaches that our inquiry is a "three-phased process. First, there is the business of finding the crude historical facts, the external, 'phenomenological' occurrences and events surrounding the confession. Second, because the concept of 'voluntariness' is one which concerns a mental state, there is the imaginative recreation, largely inferential, of internal, 'psychological' fact. Third, there is the application to this psychological fact of standards for judgment informed by the larger legal conceptions ordinarily characterized as rules of law but which, also, comprehend both induction from, and anticipation of, factual circumstances."
