Colorado Police Gave You an Inadequate Miranda Warning—Is Your Statement Automatically Suppressed?

QUICK ANSWER
In People v. Vanpelt, 2026 CO 66 (decided October 12, 2026), the Colorado Supreme Court held that a defendant’s statements and handwritten apology letter from a 75-minute jailhouse interrogation were voluntary under the due process clause, even though the prosecution conceded he never received a proper Miranda advisement. Because the detectives’ conduct did not overbear his will, the statements are not barred for every purpose.
They remain off-limits in the prosecution’s case-in-chief because of the Miranda violation, but the voluntariness ruling keeps open the possibility that prosecutors use them to impeach him if he testifies.
