Background
A Milwaukee County jury convicted William M. Acosta of first-degree reckless injury and aggravated battery arising from an assault on his girlfriend, Camila, a pseudonym used by the court. The jury also found that Acosta used a dangerous weapon, an enhancer applied to both offenses. Camila testified that Acosta punched her, but denied at trial that he used an object. Other witnesses recounted her earlier statements that Acosta beat her with objects including a wooden stick, two-by-four, wooden loofah, or glass bottle.
During deliberations, the jury asked, “Are fists considered a weapon?” With both parties’ agreement, the circuit court repeated the general statutory definition of “dangerous weapon.” It did not tell the jury that Wisconsin precedent holds that portions of a defendant’s anatomy, including bare hands, are not dangerous weapons. Acosta sought postconviction relief, alleging his lawyer was ineffective for agreeing to that response; the circuit court denied the motion without an evidentiary hearing.
The Court’s Holding
The Wisconsin Court of Appeals reversed the order denying Acosta’s postconviction motion and remanded for further proceedings, including a Machner hearing on his ineffective-assistance claim. Acosta sufficiently alleged deficient performance because longstanding Wisconsin authority, State v. Frey, directly answered the jury’s question by holding that bare hands are not dangerous weapons, yet trial counsel agreed to a response that did not provide that rule.
Acosta also sufficiently alleged prejudice. The court rejected the State’s contention that the generic instruction was adequate or that the dangerous-weapon finding was merely a sentencing matter. Under Wisconsin law, use of a dangerous weapon changes the nature of the charged crime and is an element. Given the conflicting evidence about whether Acosta used an object and the jury’s question, the record did not conclusively establish that Acosta could not obtain relief. The court did not decide the merits of the ineffective-assistance claim or the proper remedy if Acosta proves it.
Key Takeaways
- A defendant is entitled to a Machner hearing when a postconviction motion alleges material facts that, if true, establish deficient performance and prejudice.
- Wisconsin law does not treat a defendant’s bare hands or fists as a dangerous weapon under the statutory definition.
- A dangerous-weapon enhancer is also an element of the charged offense for purposes of the prejudice analysis.
Why It Matters
The decision underscores that a legally accurate general instruction may still be inadequate when it fails to answer the jury’s specific question under controlling precedent. Counsel’s response to a jury inquiry can support an ineffective-assistance claim where it permits the jury to rely on a legally unavailable theory.
The ruling is procedural: it requires an evidentiary hearing and further merits determination, rather than vacating Acosta’s convictions or selecting a remedy.
