Al’s daughter, Lexi Olinsky, tragically died in Season 5. She was a victim of a fire set by a gang leader as a warning to another gang.
In the series “Chicago P.D.,” Detective Alvin Olinsky, a key member of the Intelligence Unit, faces a devastating personal loss when his daughter Lexi becomes an unintended casualty in a gang-related conflict. The incident occurs in the episode titled “Allegiance,” which is the 21st episode of the fifth season. Lexi is caught in a building fire that was started by a gang leader aiming to send a message to a rival gang member who lived in the same building. Despite the best efforts of the firefighters from “Chicago Fire,” another show in the same universe, Lexi succumbs to her injuries.
The loss of his daughter has a profound impact on Al, both personally and professionally, and it contributes to the series of events that lead to his own dramatic exit from the show. The storyline serves as a poignant reminder of the dangers that the families of law enforcement officers can face and the personal sacrifices made by those who serve in such high-stakes roles.
