Gabriela Casey (neé Dawson) was a Firefighter on Truck 81 stationed at Firehouse 51. She is Detective Antonio Dawson's sister. Gabriela was married to firefighter Matthew Casey until she left to work at Puerto Rico. Gabriela is portrayed by Monica Raymund.


Gabriela is very devoted to her brother Antonio and his family. When Diego is kidnapped, she accompanies Antonio's wife and daughter to the Intelligence office.

She is also seen a few times as an emergency responder at the scene of a shooting or violence. One example would be when Antonio's partner Detective Julie "Jules" Willhite is shot.

Gabriela had a short-lived relationship with Detective Jay Halstead while he was working as a double agent against a ruthless stake owner of Mda.Their relationship ended when Halstead expressed his desire to join Intelligence.

She is involved in an arson case in 2x13. After her close friend and paramedic, Leslie Shay, is killed, she asks Antonio to help her by catching the arsonist, who is also accused of killing Peter Mills’ father. Intelligence takes on the case.

During season 4, Gabriela decides to adopt a boy that has been in and out of the foster care system, Louie Thompson. She ends up having full custody of him at the end of season 4 where Matthew Casey comes home from a business meeting.
