State v. Barnes
317 Neb. 517
Neb.2024Background
- Kolton Barnes was convicted of first degree murder, cruelty to an animal, two counts of use of a deadly weapon to commit a felony, two counts of negligent child abuse, and evidence tampering after the death of his fiancée, Kayla Matulka, and his dog.
- The State alleged Barnes killed Matulka after she broke up with him, with alternate theories of either deliberate, premeditated malice or during the perpetration of first degree sexual assault.
- Barnes claimed self-defense, arguing that Matulka attacked him after killing the dog, and also sought to present evidence of Matulka’s mental health issues to support alternative causes for her own or the dog's death.
- Before trial, Barnes moved to compel additional discovery of Matulka’s mental health records, which was denied after some records had already been disclosed.
- The State was permitted to admit evidence of Barnes’ prior threat to kill an ex-girlfriend under Neb. Evid. R. 404(2) as proof of motive, intent, and plan.
- The trial court's rulings on evidence, prosecutorial conduct, sufficiency, and sentencing were challenged on appeal to the Nebraska Supreme Court, which affirms the convictions and sentences.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Motion to Compel Insurer's Mental Health Records | Denial prejudiced Barnes’ defense and was constitutional error | Sufficient evidence already provided, further records cumulative | No abuse of discretion; denial upheld |
| Admission of Prior Threat Against Ex-Girlfriend (404 evidence) | State lacked clear/convincing proof and relevance; prejudicial | Evidence highly relevant for intent, motive, plan; not unduly prejudicial | Admission affirmed; limiting instruction presumed followed |
| Exclusion of Demonic Possession Document | Was authenticated by testimony; relevant to theory of Matulka’s instability | Lacked foundation; any error harmless due to cumulative evidence | Exclusion harmless error |
| Admission of Cell Phone Timeline as Substantive Evidence | Should have been demonstrative only; risk of jury misuse | Properly admitted, investigator explained; cumulative with other evidence | No reversible error, issue not preserved |
| Prosecutorial Misconduct/ Burden Shifting | Multiple statements misled jury and shifted burden to Barnes | Prosecutor’s remarks proper, invited, isolated, or cured by instruction | No prejudicial misconduct; jury presumed to follow instructions |
| Sufficiency of Evidence on Premeditation/ Self-Defense | No evidence of premeditation; self-defense not disproved | Evidence strong for premeditation, intent, conduct after the fact | Evidence sufficient for murder conviction |
| Excessiveness of Sentences | Sentences for weapons excessive due to minimal criminal history, intoxication | Sentences appropriate to violent and brutal facts, lack of remorse | Sentences within discretion, not excessive |
