An attorney for Bionca Ellis is asking an appellate court to take another hard look at her case, arguing that key legal mistakes at trial kept jurors from fairly weighing her insanity defense. Ellis was convicted in October 2025 and is serving life without parole for the June 3, 2024 killing of 3-year-old Julian Wood in a North Olmsted Giant Eagle parking lot.
According to WKYC, an appellant's brief filed April 24 by attorney Frank Cavallo argues the trial court misstated Ohio's legal standard for insanity and did not clear up juror confusion about what a not-guilty-by-reason-of-insanity verdict would actually mean. The filing also claims Ellis received ineffective assistance of counsel in violation of the Sixth and Fourteenth Amendments.
What the appeal says
"The trial court misstated Ohio's legal standard for insanity and misled the jury," the brief says, according to WKYC. The appeal asks judges to decide whether those alleged instructional errors, combined with the claimed shortcomings by defense counsel, created enough prejudice to justify reversing the conviction or ordering a new trial.
The attack and the verdict
Prosecutors say Ellis followed Margot Wood and her 3-year-old son out of the Giant Eagle and stabbed the child. Julian Wood later died of his injuries and his mother was hospitalized. As reported by the AP, investigators allege Ellis took two knives from the Volunteers of America thrift store next door before the June 3, 2024 attack.
A jury found Ellis guilty in mid-October 2025, and a judge sentenced her to life in prison without the possibility of parole on Oct. 27, 2025. The prosecutor's office statement on the case is available online. The Cuyahoga County Prosecutor's Office noted the sentence and called the attack "among the most heartbreaking."
Competency, plea and trial timeline
Ellis was previously ruled incompetent and treated at a psychiatric facility before being found competent to stand trial in February 2025, local coverage shows. During the October 2025 trial, her lawyers advanced an insanity-based defense. Forensic experts for both sides testified about her long history of mental-health hospitalizations and, according to trial reporting, a diagnosis of schizophrenia. Court TV covered the competency findings and expert testimony presented to jurors.
Legal issues to watch
The appeal zeroes in on jury instructions and counsel performance. Ohio law defines not-guilty-by-reason-of-insanity as a showing that, at the time of the offense, a defendant "did not know, as a result of a severe mental disease or defect, the wrongfulness of the person's acts" (Ohio Rev. Code § 2901.01). For claims that a lawyer’s performance was constitutionally deficient, courts apply the two-prong Strickland standard: deficient performance plus resulting prejudice.
Ohio Revised Code §2901.01 and the Strickland framework provide the legal yardsticks appellate judges will use when they review Ellis' claims. Strickland v. Washington is the controlling federal precedent on ineffective-assistance claims.
What comes next
The appellant's brief filed April 24 starts the formal appellate briefing process. The appeals court will set deadlines for the state's response and any reply from Ellis' side, then decide whether to hold oral argument or rule based on the written submissions alone.
Meanwhile, the Wood family's civil lawsuit alleging negligent security against Giant Eagle and other parties remains active and could move forward on a separate track from the criminal case. Cleveland19/WOIO reported on the parents' lawsuit, and ongoing civil filings tied to the case are reflected in the federal docket, which is viewable via Justia.
Local response
The criminal sentence brought strong public statements from elected officials and prosecutors, and those remarks remain part of the case record. Cuyahoga County Prosecutor Michael O'Malley said Ellis' actions "warrant nothing less than life without parole," a quote included in the prosecutor's press release following sentencing. The Cuyahoga County Prosecutor's Office has noted lasting community grief as the civil litigation and this new appeal continue to move through separate court systems.
