Background

  • 12-year-old Justin Bloxom was lured from a friend's house by text (perpetrator posing as a 14‑year‑old girl), entered Brian Horn’s taxi, and was later found dead; Horn’s phone sent/received the texts and the taxi key was found near the body.
  • Medical testimony established cause of death as asphyxiation/smothering with anti‑mortem injuries (abrasions, petechiae), and evidence included a latent print and SIM‑card text forensics.
  • Horn was indicted for first‑degree murder (La. R.S. 14:30(A)(1)) under a theory that the killing occurred during aggravated or second‑degree kidnapping.
  • At trial defense counsel conceded Horn killed Justin and urged the jury to convict of a lesser homicide (second‑degree murder or manslaughter) over Horn’s express objection; Horn repeatedly insisted on pursuing a theory that he did not concede guilt to the charged or lesser murder offenses.
  • The jury convicted Horn of first‑degree murder and recommended death; Horn appealed raising multiple errors, principally that counsel’s conceded guilt violated his Sixth Amendment right to control the objectives of his defense.
  • The Louisiana Supreme Court vacated the conviction and death sentence, holding counsel’s concession over Horn’s objection was a structural Sixth Amendment error requiring a new trial.

Issues

Issue Plaintiff's (State's) Argument Defendant's (Horn's) Argument Held
Whether defense counsel’s concession of guilt over defendant’s express objection violated the Sixth Amendment Concession was reasonable strategy to seek mercy/avoid death; Horn had not insisted on absolute innocence but wanted a different homicide theory (negligent homicide) Horn insisted counsel not concede guilt to charged or lesser murder offenses and objected that counsel usurped his choice of defense objective Court: Violation. McCoy controls; defendant has right to decide objective (including refusal to concede). Concession over objection is structural error → vacate and remand for new trial
Whether McCoy is limited to defendants asserting complete innocence State: McCoy should be limited to cases where defendant maintains absolute innocence (e.g., alibi) Horn: McCoy protects defendant’s autonomy to refuse concession even if pursuing an alternative non‑murder theory Court: Rejected limitation; McCoy applies broadly to defendant’s choice of defense objective, not solely to alibi claims
Whether the error is subject to harmless‑error or requires automatic reversal State: (implicitly) could argue harmless because evidence strong Horn: Structural violation of right to autonomy; prejudice not required Court: Structural error — not subject to harmless‑error review; reversal required without showing prejudice
Sufficiency of evidence to support first‑degree murder (aggravated or second‑degree kidnapping) State: Evidence supports second‑degree kidnapping (enticing via texts; physical injuries) though conceded aggravated‑kidnapping was unsupported Horn: Insufficient proof of specific intent to kill and of kidnapping aggravators Held (Weimer, J. concurrence): Evidence sufficient to support second‑degree kidnapping and, viewing facts in light most favorable to prosecution, sufficient to support guilt findings; but majority remanded on Sixth Amendment ground, not on sufficiency
