A violent day in Chicago’s South Shore neighborhood saw the shooting deaths of seven people in three separate incidents within a four-block area, police say. In a tragic continuing trend whose victims are overwhelmingly African-American, families continue to suffer the consequences of gun violence in their communities.

The first shooting took place just after noon Thursday when police got a call about a woman found in her home with a gunshot wound to the head. She was identified by WGN-TV as Patrice Calvin, 26, and was pronounced dead at the scene.

Almost four hours later, four men were killed in a shooting at a chicken and fish spot. Dillion Jackson, 20, his brother Raheem, 19, had come to visit their mother at the restaurant where she works. A man walked into the restaurant and shot Emmanuel Stokes, 28  to death along with an unidentified man.  The man then turned his gun on the two brothers, shooting them outside the restaurant. One died on the spot, the other about a block away.

But the violence did not end there.

Just after 11 p.m., a man and a woman were shot dead in a car near Chicago’s South Shore Cultural Center. Police say an SUV pulled up to the vehicle firing at it as it drove down the street, killing a 23-year-old woman in the front seat and a 27-year-old man in the back. The van coasted and hit a pole near some commuter rail tracks. A woman who saw the footage of the shooting on her home surveillance system told the Chicago Sun-Times that another individual got out of the van and ran away.

In each of the cases, no suspects have been apprehended, but police say investigations are ongoing. Chicago police spokesman Anthony Guglielmi tweeted that the quadruple shooting is believed to be a “gang related retaliation from another incident.”

The fatalities were in addition to seven other shootings in Chicago taking place from 2:00 a.m. to 10:55 p.m. in various areas around the city. The violence brings the number of people to fall victim to gun violence there this year to 740, according to the Chicago Tribune. At least 140 of them have been homicides.

Residents in the area of the South Shore shootings say they have come to a point where the violence has become numbing, but this amount of killings in one day is still surprising. “You lose count of the shootings after a while,” said Kyra Carr, who lives in the vicinity and heard gunshots. “But seven bodies in a day. Crazy. Something is wrong.”
