Quid Pro Quo

A basketball game gets ugly as a fight breaks out, forcing Danny to arrest a friend who punched an opposing player for pushing him around and calling him "fat." Jamie later learns the assaulted man, a friend of his from law school, has hired an "ambulance chaser" and instigated the fight in order to get money. Frank is interviewed by a TV reporter who brings up a condemning quote about him that is revealed to have come from a colleague. When Garrett admits to making the statement back before he really knew Frank, he tries to get it edited out even though Frank is okay with it being aired. Erin is approached by Nathan Anderson, who hopes she can solve his murdered daughter Jenny's cold case from 1998. Nathan strongly feels his daughter's boyfriend Richard Roark, a very rich and powerful man, should be the prime suspect. Erin enlists Danny's help. Nathan gives them Jenny's necklace which has blood on it. The blood sample was too small to test in 1998, but Danny states that DNA testing has advanced greatly in the last 15 years and has it tested again. The lab work leads the detectives to Richard's father, Preston. Richard confronts his father, assuming he killed her because he thought Jenny wasn't good enough for his son.
