Addicted to Love (S02E07)

Things are not as they seem when Jim Longworth and the crew investigate the murder of a beloved Haitian doctor. When a gun and $100K cash are found in the dead doctor's car, Longworth traces the money to a "pill mill," a corrupt doctor's office where addicts pay big money for pain medication. It turns out the good doctor had a lot of patients, all of whom had more than enough motive to kill. (iTunes)
