Originally called Police Woman (which may have factored into this being released, as there as a show by that title on TV at the time), DC filled First Issue Special #4 (July, 1975) with....Lady Cop!
The cover was by Dick Giordano, and the two interior stories were by Robert Kanigher, John Rosenberger and Vince Coletta.
Liza trained well, and graduated top of her class....stopping a student who had scrubbed out from tossing a grenade at the graduating class.
Still, Liza was searching for the "Killer In Boots".
Not the greatest comic story ever told, but likely something destined for a romance comic, that happened to end up here. Simple by today's standards, a nice look back at the problems that women faced when they joined the police force (and that next issue was one of Jack Kirby's Manhunter!).
