Teresa Cortez is both the mother of Ana-Lucia Cortez and the Captain of her daughter’s LAPD squad. When Ana-Lucia responded to a burglary call, she was shot by a man named Jason McCormack four times with hollow point bullets through her bullet-proof vest, and in the process lost the unborn child she was carrying. Teresa arranges for her daughter to visit with a psychiatrist named Matthew Reed who would help her deal with her issues. Teresa left the final determination of Ana’s return to the force up to Matthew.
