She’s a prostitute who trades sex for drugs or money. She works for Javier Garza, a pimp.
While investigating the murder of a Jane Doe, Officer Debra Morgan gets a lead from Anton Briggs, a C.I. She visits a pimp, Javier Garza, and shows him a photo of the victim. He makes wisecracks and denies knowing the dead woman.
A woman on a heroin high, who is lying on the sofa, looks at the photo and speaks up.
Woman: (to Javier) “You fucked her.”
Deb: (to woman) “You've seen her?”
Woman: (laughing) “On his dick.”
Javier: “Hey, she's fading. She doesn't even know what she's talking about.”
Deb: “Oh, I think she does, and I think you fucked a girl who's now dead.”
Javier, caught in a lie, finally admits that he picked up the girl in the photo at a party, but then passed her to Freebo. He denies knowing her name, though. (Later, the victim is identified as Teegan Campbell.)
