More information is coming to light about theshootingat the Dennis M. Lynch Arena during a high school hockey game on Monday. Investigators say the incident unfolded in just seconds, turning a routine community event into a terrifying scene of violence.

Shortly before 2.30 pm, players and spectators were gathered for a boys' senior high school hockey game when 56-year-oldRobert Dorgan, also known asRoberta DorganandRoberta Esposito, opened fire. Police described the attack as 'very targeted,' noting that Dorgan approached members of his own family before firing.

At first, witnesses mistook the rapid shots for normal rink noises — skates scraping ice or pucks hitting boards — until the reality of the situation became clear. Authorities confirmed that Dorgan fired multiple shots in rapid succession, sending the arena into immediate panic.

Two people were killed:Dorgan's ex-wife, Rhonda Dorgan, and their adult son,Aidan Dorgan. Three others — including Rhonda's parents and a family friend — were critically injured and rushed to the hospital. The suspected shooter was later found dead at the scene from an apparent self-inflicted gunshot wound, according to police.

Investigators have reconstructed thetimeline of the attack. Dorgan fired 13 shots in about six seconds, paused briefly, and then fired a final shot around 11 seconds later. Understanding this sequence helped authorities see how quickly the situation escalated and how bystanders reacted.

Spectators and players reacted instantly, with some diving for cover and others fleeing the arena. The rapid events created a chaotic, intense scene that unfolded in moments.

Authorities said a bystander helped bring the attack to a swift end, though details of their actions have not been released. Officers arrived within minutes, secured the arena, and ensured there was no further threat.

The fast response from law enforcement and first responders was critical in limiting additional injuries and restoring order.

Eyewitnesses described the scene as sudden and overwhelming. Parents and students ducked under seats or pressed against walls, while players on the ice scrambled toward benches and locker rooms for safety.

Many later told investigators that the speed and intensity of the gunfire left them very little time to react. Law enforcement said these accounts were crucial to piecing together the attack timeline.
