A police officer off duty heard a strange noise coming from downstairs while his pregnant girlfriend (she looks like Dido in Eminem "Stan" video) was watching TV. Shortly after knocking the door he tried to get in and a guy with a hoodie shooted him to death two times before running away. Detectives thought at first he could be a paparazzi (who owned the flat), but a cover magazine drove the attention of the only witness: the perp is a white rapper (Wayne Wilcox) and the murder weapon was found inside a junkie friend's hometown. The paparazzi had some pictures of a starlette and her newborn son (other than further compromising photos) and he sold them to a sixth page reporter. The girl is rapper's wife, but the motive is revealed only at the end of episode on the stand.
After Fontana retired, a rookie took his place. She's charming (she could compete with the new ADA for the first place in a beauty pageant) as well as stubborn but she still has a lot to learn. Luckily Green is sympathetic towards her.
