State v. Mattox, 390 P.3d 514

Background

Victim Keighley Alyea was abducted and brutally killed; Mattox (defendant) was implicated by physical evidence and gave a detailed confession describing robbery, kidnapping, and murder with co-defendants.
Mattox was convicted by a jury of first-degree premeditated murder (aiding and abetting), aggravated kidnapping, and aggravated robbery; district court imposed a "hard 50" life sentence without jury finding on aggravators.
Mattox moved to suppress his confession claiming invocation of counsel, involuntary Miranda waiver, and promises of leniency; the district court denied suppression after hearing expert testimony on his mental state.
Pretrial Mattox attempted to plead nolo contendere to lesser counts; the court refused, citing doubts about factual basis given Mattox’s intended mental-defect defense.
Evidence rulings: trial court excluded the contents of a text message to Mattox’s father as inadmissible hearsay (excited utterance exception rejected for lack of context).
On direct appeal the Kansas Supreme Court affirmed convictions, vacated the hard 50 sentence (Alleyne Sixth Amendment error), and remanded for resentencing.

Issues

Issue	State's Argument	Mattox's Argument	Held
Constitutionality of hard 50 sentencing	Hard 50 may be imposed under statute; judge found aggravators	Judge’s findings (not jury) increased mandatory minimum, violating Sixth Amendment	Vacated hard 50; Alleyne requires jury find facts increasing mandatory minimum beyond reasonable doubt
Aiding-and-abetting / intent jury instruction	PIK 3d 54.05 correctly instructed aiding and abetting; jury need not be told defendant must share identical premeditation beyond instruction set	Requested instruction that aider must share principal’s premeditation; current phrasing could confuse jury	Instructions as a whole were proper; no reversible error (better practice to add clarifying language)
Multiple-acts / unanimity instruction request	Single homicide cannot give rise to multiple acts for unanimous verdict problem	Mattox argued separate assaults across times/locations required unanimity instruction	No multiple-acts error—only one killing; unanimity instruction not required
Suppression of confession (invocation of counsel)	Mattox’s question was ambiguous; detectives properly clarified; waiver was knowing and voluntary	Mattox argued he asked for a lawyer and was effectively denied/pressured to continue	Invocation was not unambiguous; Miranda waiver and confession were voluntary under totality of circumstances
Refusal to accept no-contest pleas to lesser counts	Court reasonably doubted factual basis for pleas given asserted mental-defect defense	Mattox argued court abused discretion and failed to conduct K.S.A. 22-3210 colloquy	Refusal was within discretion; court reasonably found lack of factual basis so full colloquy unnecessary
Exclusion of text message as excited utterance	Text content was hearsay without context; no exception applies	Text admissible as excited utterance or statement of condition	Exclusion affirmed: insufficient context to meet excited utterance factors
Right to counsel at State psychiatric exam	Examination was not a "critical stage" triggering Sixth Amendment presence right	Mattox contended he had a right to counsel during the State expert’s evaluation	No Sixth Amendment right to counsel at such evaluations; evidence admissible (subject to trial rulings)
