Shooting Erupts at University of Dayton Halloween Party, Suspect Arrested

On November 1, 2025, a shooting incident occurred at a Halloween party in the University of Dayton student neighborhood. According to federal court documents, the incident is being described as a "shootout" by investigators.

A 19-year-old student sustained non-life-threatening injuries during the shooting. Authorities have arrested 19-year-old Dylan Hiner and charged him with federal weapons offenses in connection with the incident.

The court documents indicate that Hiner was on pretrial release for previous weapon-related charges and on probation for a misdemeanor conviction at the time of the shooting. A federal judge has ordered Hiner to remain in the Shelby County Jail as he awaits trial, stating that the defendant's "past use of firearms and his apparent attitude toward them pose a significant risk of danger to the community."

In addition to Hiner, three other individuals - a 17-year-old boy, a 16-year-old girl, and a 15-year-old boy - have also been arrested in connection with the shooting. However, it remains unclear whether any of the arrested individuals are believed to be the person who shot the student.

The University of Dayton has announced that it will hold a town hall meeting on Sunday to address the incident and provide updates to the community.
