Overview
- Searches of Robert Dorgan’s apartment and a Brunswick, Maine, storage unit recovered an AR-15 style rifle, a sawed-off shotgun, ammunition, firearm accessories and electronic devices.
- ATF traced two handguns used inside the arena to prior purchases: a 10mm Glock 29 bought in Jacksonville, Florida, in 2021 and a Sig Sauer P226 bought in West Warwick, Rhode Island, in 2019.
- Police say bystanders Michael Black, Robert Rattenni and Ryan Cordeiro subdued the shooter, actions credited with preventing further harm, before Dorgan drew a second gun and died by suicide.
- Three surviving victims remain hospitalized in critical condition, including assistant principal Tom Geruso, as community vigils and counseling efforts continue.
- Authorities note the case remains a targeted family attack with no established motive, while journalists have documented tattoos linked to white-supremacist imagery and extremist posts now under review.
