Inadmissible Hearsay Text Messages Are Not Harmless When They Bolster the Complainant and Undercut the Defense on Theft Elements and Value
Case: State v. B. Henderson, 2026 MT 17 (Mont. Feb. 10, 2026)
Court: Supreme Court of Montana
Posture: Defendant appealed felony theft conviction; State conceded hearsay admission error and argued harmlessness.
1. Introduction
State v. B. Henderson arises from the alleged removal of property from a storage unit (unit G-25 at A1 Eastside Storage in Great Falls)
after the complaining witness, Sharen Zeman, reported that approximately $12,000 in items had been stolen. Billie Jo Henderson—who had been living with Zeman
and later moved out—was charged with burglary and theft. Video evidence showed Henderson (and co-defendant Teona Baker) entering the facility using a gate code
tied to the unit and removing items from the unit on April 4, 2022.
The trial pivoted on two interrelated issues: (i) whether Henderson’s control over the property was “unauthorized” and purposeful, and
(ii) whether the State proved the statutory value band necessary for the specific felony theft verdict returned by the jury (over $1,500 but less than $5,000).
A central evidentiary dispute concerned a Facebook Messenger text exchange between Zeman and Baker, which the District Court admitted over objection.
On appeal, the State conceded the messages were inadmissible hearsay; the only question was whether admitting them was harmless error.
2. Summary of the Opinion
The Montana Supreme Court reversed Henderson’s conviction and remanded for a new trial. Applying Montana’s harmless-error framework, the Court held there was a
reasonable possibility the inadmissible hearsay texts contributed to the conviction. The Court emphasized that:
- The State used the texts to prove all four theft elements (ownership, unauthorized control, purpose to deprive, and value band).
- The case was a credibility contest; the texts materially bolstered Zeman and damaged Henderson.
- Henderson’s limited admission (that she inadvertently removed some of Zeman’s items and may not have returned “maybe a couple things”) did not
establish the value element for the felony level of conviction returned.
3. Analysis
3.1 Precedents Cited
Harmless error framework and burden
-
State v. Van Kirk, 2001 MT 184, ¶¶ 37-43, 47, 306 Mont. 215, 32 P.3d 735
Van Kirk supplies the governing two-step prejudice analysis:
(1) classify the error as structural or trial error; (2) if trial error, determine harmlessness.
The key standard—quoted and applied here—is that the State must show “no reasonable possibility”
the inadmissible evidence contributed to the conviction. Henderson is a straightforward but significant application:
the Court treated hearsay admission as a trial error and placed the full burden on the State to negate any reasonable possibility of contribution.
-
State v. Santillan, 2017 MT 314, ¶¶ 34-35, 390 Mont. 25, 408 P.3d 130
Santillan refines Van Kirk by tying the harmless-error showing to the role of the tainted evidence.
If admitted to prove an element, the State must point to cumulative admissible evidence proving the same facts and show the tainted evidence’s
quality could not have mattered. Henderson uses this element-focused lens to reject harmlessness because the texts were deployed across elements—especially
authorization/intent and value-validation—without adequate admissible substitutes of comparable force.
-
State v. Derbyshire, 2009 MT 27, ¶ 54, 249 Mont. 114, 201 P.3d 811
Henderson reiterates Derbyshire’s “qualitative” emphasis: harmlessness turns not on whether there is other evidence in the record,
but on whether—in context—there is no reasonable possibility the tainted evidence affected the fact-finder. The Court’s analysis is quintessentially qualitative:
the texts were rhetorically powerful (calling Henderson a liar, implying consciousness of guilt, corroborating disputed access facts), making them difficult to treat as benign.
-
State v. Hunt, 2025 MT 122, ¶ 48, 422 Mont. 322, 570 P.3d 567
Hunt provides the general admonition that convictions are not reversed absent prejudice from improper evidence.
Henderson operationalizes that principle by identifying concrete prejudice mechanisms: credibility bolstering, credibility destruction, and element proof—rather than abstract error.
Structural vs. trial error and the constitutional reference point
Standard of review and evidentiary rulings
-
State v. Burchill, 2019 MT 285, ¶ 13, 398 Mont. 52, 454 P.3d 633
Used for the baseline rule: evidentiary rulings are reviewed for abuse of discretion.
Henderson’s substantive work, however, occurs after the State’s concession of error—making prejudice/harmlessness determinative.
-
State v. Stewart, 2012 MT 317, ¶ 23, 367 Mont. 503, 291 P.3d 1187
Cited to note de novo review when a ruling turns on interpretation of an evidentiary rule or statute. In Henderson, the Court does not need to resolve the hearsay
question independently because the State concedes inadmissibility; nevertheless, the citation frames how such disputes are normally reviewed.
-
State v. Grimshaw, 2025 MT 250, ¶¶ 16, 25, ___ Mont. ___, 578 P.3d 890
Provides (i) a definition of abuse of discretion and (ii) the reminder that harmlessness is fact-dependent. Henderson exemplifies that fact-dependence by tying harmlessness
to the trial’s credibility structure and to which theft elements lacked strong admissible support (notably value).
Side note on jury selection issue (not reached)
-
State v. Hillious, 2025 MT 53, 421 Mont. 72, 565 P.3d 1218
Henderson initially raised a jury-selection compliance argument under § 3-15-405, MCA (2023), but conceded in reply that Hillious controlled.
While not part of the holding, this illustrates the Court’s current approach: statutory jury-selection irregularities require a showing that randomness was affected or subjective criteria were used.
3.2 Legal Reasoning
(a) Error classification
The parties agreed the texts were improperly admitted hearsay. The Court treated this as a trial error (not structural), thereby invoking
harmless-error review under Van Kirk.
(b) What the texts did at trial (why “quality” mattered)
The Court’s harmlessness rejection turns on a detailed account of how the State used the exchange:
-
Unauthorized access and deception: The texts suggested Baker got the gate code from Zeman under false pretenses, supporting the narrative that Henderson’s access was unauthorized.
-
Ownership and the property list: The State argued the texts mirrored the same categories of items on Zeman’s list, using them to validate that list and its asserted scope.
-
Intent/purpose to deprive and return narrative: The texts implied only damaged items were returned and framed the dispute as theft rather than mistake.
-
Credibility and consciousness of guilt: Baker’s statement, “She said that was mostly her clothes I don't know why I believed her,” directly branded Henderson as deceptive,
and another message implied Henderson warned Zeman she would “be in a lot of trouble” if police were called—an invitation to infer guilty knowledge.
(c) The missing admissible substitute—especially on value
The Court acknowledged Henderson’s testimony included an admission that she removed some of Zeman’s property and may not have returned “maybe a couple things,”
which could support some elements of theft. But the Court found that admission did not prove the value band required for the felony level of conviction returned.
Other State evidence (video of entries, manager testimony, officer testimony) did not identify specific high-value items with clarity or establish value independently.
(d) Why the Court could not say the verdict was unaffected
Because this was a credibility contest—Zeman’s account versus Henderson’s permission-and-mistake defense—the texts’ credibility effects were not peripheral.
On that record, the Court concluded there was a reasonable possibility the jury either:
- would have acquitted of felony theft absent the texts, or
- would have convicted of a lesser value tier (including theft at $1,500 or less), given the weakened proof of value without the tainted corroboration.
3.3 Impact
Practical impact on prosecutions involving digital communications
Henderson is a cautionary precedent for cases where the State relies on social media messages or texts between a complainant and a co-defendant:
even when there is other incriminating evidence (e.g., surveillance of entry), admitting hearsay communications can be outcome-determinative if they:
(i) supply narrative glue for disputed elements (authorization/intent),
(ii) buttress disputed valuation proof, or
(iii) materially reshape credibility.
Doctrinal impact on harmless-error arguments
The decision reinforces an exacting, element-sensitive harmless-error review:
it is insufficient for the State to point to “some evidence of guilt.” Where the tainted evidence was used to prove elements,
the State must identify admissible evidence proving the same facts with comparable persuasive force and show the tainted evidence could not have mattered.
Henderson illustrates that credibility-damaging hearsay can defeat harmlessness even when a defendant makes partial admissions.
Trial-court and litigant takeaways
- For trial courts: hearsay determinations in the digital-message context require careful gatekeeping because the appellate lens is qualitative and credibility-focused.
- For prosecutors: if texts are central, they must be admitted through a valid non-hearsay theory or a recognized exception, or supported by alternative admissible proof of the same facts (especially value).
- For defense counsel: where the State’s value proof is thin, improper corroborative statements can be strong grounds for reversal under the “reasonable possibility” standard.
4. Complex Concepts Simplified
-
Hearsay: an out-of-court statement offered to prove the truth of what it asserts. Here, the Facebook messages were used to prove facts about permission, theft, and what was taken.
-
Structural error vs. trial error: structural errors undermine the basic framework of a trial and require automatic reversal; trial errors occur during evidence presentation and are reviewed for harmlessness.
-
Harmless error (“no reasonable possibility”): the State must show the improper evidence could not reasonably have affected the verdict. If the evidence might have mattered, reversal is required.
-
“Qualitative” review: courts assess persuasive force and role at trial—not just whether other evidence exists.
-
Consciousness of guilt: conduct or statements suggesting a defendant knew they were guilty (e.g., implied threats about calling police). Such inferences can strongly sway juries, making improper evidence harder to deem harmless.
-
Value element in theft: some theft offenses depend on the monetary value of the property; if value is not proved to the required range, the degree of the offense changes.
5. Conclusion
State v. B. Henderson underscores that wrongly admitted hearsay texts can rarely be shrugged off as harmless when they function as
credibility arbiters and element proof—particularly for theft valuation. Even with surveillance showing access and a defendant’s partial admission, Montana’s
harmless-error doctrine demands a rigorous showing that there is no reasonable possibility the tainted messages contributed to the verdict.
Because the texts both bolstered the complainant and undermined the defense in a close credibility-driven case—without strong admissible substitutes on value—the conviction was reversed and remanded for a new trial.
