Lady Cop

The Lady Cop is a fictional police officer, a comic book character published by DC Comics. She debuted in 1st Issue Special #4 (July 1975), and was created by Robert Kanigher and John Rosenberger.

The Lady Cop is Liza Warner, a young woman who watches from beneath a bed as a murderer in cowboy boots slaughters her two roommates, leaving the ace of spades behind as his calling card. Later a policewoman (circa 1975) praises her eidetic memory, calling her a "born police officer". Liza enrolls in the unnamed metropolitan city's police academy, performing her civic duty while hoping to one day find the mysterious "killer in boots". After a long absence, Liza Warner appeared in The All-New Atom #6 and #12, now as chief of police for Ivy Town.

Liza Warner appeared in the fourth and fifth seasons of Arrow, portrayed by Rutina Wesley.
