The fan-favorite character was killed off
Yuri Sardarov made his mark on Chicago Fire, after signing on as Brian “Otis” Zvonecek in 2012. Following an impressive seven-year tenure on the show, however, the actor was brutally killed off in 2019, with Otis dying in a pressure valve explosion.
Called to a mattress factory with the rest of Firehouse 51 in the season seven finale, the fan favorite was fatally wounded in the line of duty, and after a major cliffhanger, was confirmed dead in the series eight premiere.
So, what happened? As it turns out, the writers had given Otis’ death a great deal of thought after deciding that they needed to kill off a character. In an interview with TV Line, showrunner Derek Haas explained their reasoning.
