Colo.2021Background
- Fifteen-year-old K.H. was hospitalized after using methamphetamine; he told a school resource officer, Deputy Mark Johnson, that he used meth after attending a concert with his adult stepsister, Justine Murphy.
- At the hospital interview, Deputy Johnson asked whether K.H. got the drug from Murphy; K.H. gave a nonverbal response on the recording and later told the deputy (and at trial) that he did not want to say who supplied the drugs.
- Deputy Johnson testified that K.H. looked down and away and, "based on my training and experience," he took that body language as an affirmative that Murphy provided the drugs; he then asked a follow-up about whether she gave or sold the drugs.
- Murphy was charged with distributing a controlled substance and contributing to the delinquency of a minor; the jury convicted her.
- On appeal a division of the Colorado Court of Appeals reversed, holding Deputy Johnson’s testimony improperly exceeded CRE 701 as lay opinion and amounted to an impermissible comment on a witness’s credibility; the Colorado Supreme Court granted certiorari.
- The Colorado Supreme Court (majority) reversed the court of appeals, holding the deputy's testimony was admissible — either as lay opinion under CRE 701 (majority) or, per concurrence, as permissible explanation of interview tactics (Boatright concurrence). Justice Gabriel dissented.
Issues
| Issue | Plaintiff's Argument (People) | Defendant's Argument (Murphy) | Held |
|---|---|---|---|
| Whether a police officer’s testimony interpreting a witness’s body language is admissible as lay opinion under CRE 701 or requires expert qualification | Deputy Johnson’s statements were rationally based on his perception, helpful to jury understanding, and within ordinary experience; any reference to training did not convert it into expert testimony | Testimony amounted to lay opinion cloaked with officer training, effectively expert testimony or an improper comment on K.H.’s credibility | Majority: Admissible as lay opinion under CRE 701; passing reference to training did not make it expert; not improper credibility comment; reverse court of appeals |
| Whether the deputy’s reference to his "training and experience" converted lay testimony into expert testimony under CRE 702 | Such a passing reference is not dispositive; the critical question is the basis of the opinion and whether ordinary persons could reach the same inference | The testimony relied on specialized interviewing experience and thus should have required expert designation | Held: Reference alone did not transform testimony into expert opinion; the basis was within common experience |
| Whether the testimony impermissibly commented on the credibility of another witness (CRE 608/common law) | The deputy’s comments explained why he changed interrogation tactics—not an opinion on truthfulness—and served to provide context for his follow-up questioning | The deputy’s interpretation effectively said the witness was deceptive and affirmed Murphy gave drugs, invading the jury’s role to assess credibility | Held: Not an improper credibility opinion because it explained interview strategy; better practice would be a limiting instruction but no reversible error |
| Whether any error in admitting the testimony was harmless | N/A (People contended admission was proper and not harmful) | Appellate division held error was not harmless because case turned on K.H.’s credibility | Majority did not reach harmless-error analysis because it found admission proper; dissent would have found error not harmless and affirmed reversal |
