Anthony Bruno, Kansas City Firefighter, Shot Dead In Post-Wedding Assault Of Off-Duty Cop

An officer responding to an alleged assault ended up shooting a Kansas City firefighter dead after the man reportedly got violent.

A Kansas City Police officer responded to a report of a taxi driver being beaten by firefighter Anthony V. Bruno. A family member told ABC News that incident began as a dispute over a fare. Bruno, 26, had left his wedding reception to help a drunk guest into the cab.

A spokesman told KSHB that the responding officer was off duty but in uniform when he encountered Bruno.

Bruno fled.

Once the officer caught up to Bruno, the firefighter allegedly resisted arrest, and hit the officer in the head and face, according to WDAF. The officer was beaten so badly that he had to be hospitalized for head injuries.

“The subject started assaulting the officer, and that got pretty bad,” KCPD spokesman Tye Grant told KSHB. “That officer, in fear of his life, eventually fired his gun, striking the subject.”

The officer fired two fatal shots before passing out, police told KCMO. The officer was still unconscious when backup arrived. Bruno later died at an area hospital.

In a statement obtained by WDAF, the Kansas City Fire Department remembered Bruno as a courageous and dedicated firefighter who had been with the department since 2008. He was a third-generation member of the fire department.

Grant told ABC News that the officer, who has not been named, will need surgery to repair facial injuries.
