Usually when an actor leaves a show the show will do a send off. They only showed Olinsky going into surgery. Also, you can find online if the actor is leaving, written out. You get a heads up. I hope I am right and somehow Olinsky never died and we will see what happened next season. I have never replied on message boards, but Chicago PD is my fave and my fave character is Olinsky. I love his character. Does anyone else believe he is still alive?
