why did peter krause leave 911

Peter Krause left the show "9-1-1" because it was a creative decision made by the show's showrunner, Tim Minear, and not Krause's own choice. Minear explained that killing off Krause's character, Captain Bobby Nash, was necessary to keep the stakes real and the show engaging. The decision was meant to show the actual dangers faced by first responders and to open up new story opportunities for other characters. Krause fully understood and professionally supported this creative choice. The character's death was also in line with his tragic story arc, and Krause described it as a bold creative choice where Bobby's sacrifice honored real first responders who risk their lives.
