S11E9: Left to Burn; Trigger Happy

When fire fighters in Detroit respond to a house fire and discover a 63-year-old woman stabbed and bound, Sergeant Kenny Gardner and Investigator Barbara Simon must investigate the brutal murder. With no witnesses, they have to rely on the local community to help them find her killer. In Charlotte, Detective Phil Rainwater and the homicide team are called out to a restaurant parking lot littered with shell casings, where a 20-year-old father was shot dead. Surveillance video shows their potential suspects fleeing the scene in a white SUV. If they can track down the car, they may find the shooters.
