A Philadelphia native, Lieutenant Joanna Reece is the newest member of downtown Manhattan's 31st Precinct. Hired by the New York City Police Commissioner to whip the downtown precinct into shape, Lt. Reece is a stickler for protocol but will give her detectives room to improvise when needed. Although not entirely excited about Dr. Henry Morgans instincts, she allows him to partner with Detective Jo Martinez because his special talents have helped solve a number of the precinct's homicide cases.Though quick to reprimand Henry, Reece secretly admires his innate ability to see the unseen in a case or victim, as well as the effect his friendship has had on Jo, who is her prize mentee. Lt. Reece is tough and resolute but often surprises her detectives by backing them up when they least expect it.
