Paramedic Leslie Shay

Former Paramedic Leslie Elizabeth Shay, Ambulance 61 (seasons 1–2; guest, season 3): As an experienced paramedic, Shay was the designated ambulance driver and was well-liked by the mostly male crew of 51. She and Kelly Severide shared an apartment as roommates and were best friends. Popular with her co-workers, she was openly gay, often cracking self-deprecating jokes about it. She was killed in the season 3 premiere, continuing from the season 2 finale cliffhanger, in which a serial arsonist intentionally set a trap for the first responders. In "Three Bells", she was honored and remembered by her fellow coworkers at 51. She is memorialized by an inscription painted on the cab doors of Ambulance 61.
