Mission starts when Frank receives a signal from Stacey about a woman dressed like a police officer hiding inside Hot Excitorama. When he finds her there, she reveals that she is not a police officer but a peepshow performer in erotic outfit. She will join Frank after a short conversation.
When she is picked up, Frank says "You're much nicer than the last female cop I met," a reference to Jo Slade, whom Frank fought in the first game.
The amount of money she gives you (6,900) humorously refers to the sexual act 69.
The name, Deidre Sanchez, is probably a play on Dirty Sanchez, a sexual act.
If you give her a massager she will refuse to give it back or take any other weapons or food items.
Deidre deals enhanced unarmed melee damage, similar to the Guardian Angels and Tomomi Miyamoto, but unlike them she does not use a special melee attack and therefore is limited to mostly pushing zombies if unarmed.
Deidre has the same last name as Miguel Sanchez, one of the convicts in Dead Rising. However, it is unknown if they are related.
