"Fay Furillo"
"Frank's" ex-wife, "Fay Furillo" appeared several times at the beginning of the series. She was always seen constantly nagging to "Frank" about alimony, child support, and her own life problems. Eventually "Frank" has enough, and tells her to leave him be, due to the fact that they are not married anymore. She gets romantically involved with a few of the officers on "Frank's" task force afterwards.
