The show is called Southland. One of the huge focus of this show (TNT) is a university called "SULA" which is in a certain neighborhood. In this particular episode it is around the murder of a woman named "Nicole" who is track star at the University. She was murdered. She was dating the University's star line backer "Tyler Prescott." Assault charges were filed against him but the charges were dropped. Just watch the episode (linked above). I am pretty sure it will get you curious enough to track all the other shows on TNT.
