Tom Matthews

Tom Matthews is a high-ranking Miami Metro PD police official who serves as its deputy chief. Previously, he served as commanding officer of Miami Metro PD Homicide Division and the immediate superior of Lieutenant María LaGuerta. Before this, he was a lieutenant himself, serving as superior of, and best friend of, Harry Morgan. When Harry committed suicide, apparently having burned out from witnessing too many failures in the justice system, Matthews used his influence to bury any indication of suicide, and fulfilled a promise he made to Harry to look after Dexter and Debra; which is what he has done to this day.
