Ramirez's mother was the unnamed and unseen mother of Detective Anna Ramirez.

Anna was heard various times in the movie commenting on her mother who was in a hospital. Towards the end of the film, Anna was ordered to trick Gordon's wife into taking her children to 250 52nd street, by Harvey Dent as Two-Face. Two-Face was furious how she was corrupted by the Joker, along with the late Michael Wuertz, whom he had earlier shot. She claimed that she was forced to obey the Joker, due to money in order to pay her mother's hospital bills.
