Cardman v. People, 2019 CO 73

Background

Defendant Matthew Cardman was arrested after allegations that he sexually abused a seven‑year‑old who lived in his household; he was interviewed in jail by Det. Paul Patton and later convicted on multiple sex‑offense counts.
At a recorded jail interrogation, Detective Patton repeatedly promised that if Cardman "met [the child] halfway," apologized, and admitted to limited inappropriate conduct (rather than pervasive abuse), the case could be "put in a drawer" and would not proceed; Cardman then made incriminating admissions and wrote an apology.
Cardman moved pretrial to suppress statements on Fifth‑Amendment grounds (invocation of counsel / right to remain silent), but defense counsel did not specifically argue the voluntariness of the confession or seek a voluntariness hearing; the trial court denied suppression without addressing voluntariness and admitted the statements at trial.
On appeal the court of appeals treated the unpreserved voluntariness claim as waived; this Court granted certiorari, held the failure to raise voluntariness was a forfeiture (not a waiver), applied plain‑error review, and concluded the confession was involuntary and its admission was plain error requiring reversal and remand for a new trial.
The majority emphasized that the detective’s repeated promises were coercive and overbore Cardman’s will; the court rejected the proposition that Crim. P. 41(g) procedural requirements automatically convert forfeiture into waiver.

Issues

Issue	Plaintiff's Argument (Cardman)	Defendant's Argument (People)	Held
Whether failure to raise voluntariness at trial is waiver or forfeiture	Failure to raise the voluntariness claim was neglect (forfeiture), so claim is reviewable for plain error	Rule Crim. P. 41(g) requires pretrial suppression motions; failing that is waiver because counsel is presumed to know procedure	Forfeiture, not waiver; claim subject to plain‑error review
Whether the confession was voluntary	The detective’s promises were coercive and induced the confession; statements involuntary and inadmissible	The statements were voluntary: Miranda was read and waived; no adequate showing that promises overbore will	Confession was involuntary: promises and interrogation method overbore Cardman’s will; admission was error
Whether the unpreserved error is reviewable under plain‑error standard	Plain error review applies and the error satisfied all three prongs (error, obviousness, undermined fairness)	Allowing plain error here undermines Crim. P. 41(g) and policy favoring pretrial resolution; remedy should be postconviction ineffective‑assistance proceedings	Error was obvious and undermined trial fairness given confession’s centrality; reversal and new trial ordered
Remedy when officer promises induced confession	Suppression or new trial without confession; specific performance of promises not required where new trial suffices	Specific performance might be sought, but prosecution opposed	New trial without the confession is appropriate; specific performance denied as unnecessary
