For the second time in a week, a transgender person has exploded in a display of spectacular, bloody violence. The latest incident unfolded on Monday in Pawtucket, Rhode Island, where a 56-year-old man reportedly wearing a dress shot four of his family members and a family friend at a high school hockey game. Police say Robert Robert Dorgan (aka Roberta Esposito) killed the mother of his children and one of their kids before taking his own life.

Dorgan's son was reportedly playing in the game that was underway his murderous rage unfolded. Video captured Pawtucket's Dennis M. Lynch Arena as it transitioned from spectator event to deadly madness. As some 15 shots ring out in progressively more rapid sequence, players and fans gradually grasp the reality of what is happening -- first ducking for safety and then fleeing the arena any way they can. After a several-second delay, one final shot can be heard: apparently fired by Dorgan into his own head: 

Police say a bystander intervened to stop Dorgan's attack. That hero was able to disarm Dorgan, but the trans shooter had a second firearm in reserve, which he retrieved and used to kill himself. "[The bystander] interjected in this scene, and that's probably what led to a swift end of this tragic event," said Pawtucket Police Chief Tina Goncalves. In this alternate video, Dorgan can be seen descending the arena steps before opening fire and then being engaged by the bystander:
