Sgt. Roberta Hansen

Roberta Hansen, played by actress: Marta DuBois - is a sharp-tongued homicide detective with the LAPD. She and McBride share a somewhat mysterious romantic past, but have put aside their entanglement to work together as friends. Though sometimes at odds, McBride and Roberta respect and trust one another, often coming together to solve crimes everyone else has abandoned. In later episodes, Roberta's office moves from a roomier one in the corner of the police headquarters to one closer to the middle of the station. Though it is never explained in the story, the switch was made for shooting reasons because the corner office was more difficult to light.
