Three people were shot early Sunday morning in the Back of the Yards neighborhood, police said, with one of the three dead. Two people are being questioned for the case. A 36-year-old man was killed at a party in the Gresham neighborhood overnight when someone drove by and opened fire. Another man was found dead in a car, in the Woodlawn neighborhood, believed to have been shot in the back.
