A Dane County court has found Zachary O’Connell incompetent to stand trial in a fatal 2024 shooting in Sun Prairie, suspending the criminal case while he is evaluated and treated. The finding was made Tuesday, Sept. 29, by the court and a doctor, according to court records. The records indicate O’Connell is likely to regain competency within the period allowed by law. O’Connell is accused of killing William Flanary in a shooting on Martin Street on Oct. 18, 2024. He faces charges of first-degree intentional homicide, two counts of attempted first-degree intentional homicide — including one involving an unborn child — and first-degree recklessly endangering safety. The latest ruling follows a May competency hearing that found O’Connell competent to proceed. A finding of incompetency addresses a defendant’s ability to participate in court proceedings; it is not a determination of guilt or innocence.
