Police identified the gunman who killed two people and critically injured three others at a high school hockey game in Rhode Island on Monday afternoon as Robert Dorgan and revealed he went by a female name. The 56-year-old father, who shot family members and a family friend before he turned the gun on himself following the deadly rampage at the Pawtucket ice rink, used the alias Roberta Esposito, Pawtucket Police Chief Tina Goncalves said during a press conference Monday night. “We have identified the person, the suspect, by a birth name, the birth name was Robert Dorgan,” Goncalves said.
