Otis, whose real name is Brian Zvonecek, dies in the line of duty early in season 8 of Chicago Fire after being critically injured at a mattress factory fire.
On-screen events
During a major blaze at a mattress factory at the end of season 7, a boiler explodes while Firehouse 51 is inside, leaving Otis badly injured. He is pulled from the scene and taken to the hospital, but his injuries are too severe, and he later dies with his best friend Joe Cruz at his bedside.
Aftermath in the show
Otis’s death deeply affects the entire firehouse, leading the team to create a memorial at Firehouse 51 in his honor. Later, Cruz and his wife name their baby Brian “Otis” as a tribute, and the bar Molly’s North is closed following his death, underlining how much he meant to their lives.
Why the character was killed
The decision to kill Otis was made by the writers and producers, not because the actor demanded to leave, but to raise the stakes and show that the dangers the firefighters face are real. The showrunner has explained that choosing a well‑loved original character like Otis emphasized the risk and emotional cost of the job more than a less-established character’s death would have.
