Transgender Gunman Involved in Shooting at Hockey Game
A transgender individual named Robert Dorgan, who identified as “Roberta,” is the suspect in the shooting that left two family members dead during a high school hockey game on Monday. Dorgan possessed two handguns, specifically a Glock 10mm and a SIG Sauer P226, both acquired legally. Additionally, Dorgan held a concealed carry permit from Florida.
Interestingly, research indicates that many mass shooters in the past two decades have acquired their firearms through background checks. In fact, a report highlighted numerous high-profile shooters who successfully passed these checks before their attacks.
