Jo Slade

Jo Slade is a heavy-set police officer who can be found in the Lovely Fashion House in Wonderland Plaza on the 2nd floor once you receive a call from Otis for the mission. She is presumably lesbian due to her sexual (but abusive) actions towards Kay Nelson, Lilly Deacon, Kelly Carpenter, and Janet Star, the four young women she took hostage. It is likely that due to her highly corrupt nature, she is not a police officer, but dressed up as an officer to gain trust from women.

Jo may have been the one who shot Ross Folk after unsuccessfully attempting to kidnap his girlfriend Tonya Waters. Tonya mentions that Ross was shot trying to protect her.

In Dead Rising: Chop Till You Drop, there are multiple zombie versions of Jo throughout the mall, with a stun gun in each hand. None of her hostages appear in the game.

Tactics
Be warned that Jo can slam you into the ground with her fist, dealing minimal damage. She will also zap you with the stun gun, immobilizing you for a short window of time. Jo will either stomp on you when immobilized, or continue to harass the girls. Periodically, she will also shoot you with a handgun.

An easy way of killing her is to find a sledgehammer and slam her to the ground, or get a machete and slice her up. Note that you will need a lot of food, so check in both cardboard boxes. In the Wonderland Plaza there is the Mini Chainsaw from fighting Adam the Clown. Using this weapon you will only need a few hits.

Wii version
Jo appears in two zombie forms in the Wii version. The blue-shirted Jo wields only two stun guns, deal not much damage, appears at night. The brown-shirted Jo has a baton and a handgun to attack, harassing the player very much, appears during daytime. These Jo's replaces each other when the game progresses.
