Two people were killed and five others were wounded after a drive-by shooter unleashed a hail of gunfire at a crowd outside Reynold’s Lounge early Sunday morning on the South Side.

The shooting unfolded at 2:01 a.m. when at least one person inside a silver-colored Ford began firing at people gathered in front of the bar at 938 E. 75th St. in Grand Crossing, according to Chicago police. The group had spilled outside after a fight started inside the bar.

Four men and three women were struck by the shooter, police said.

Marvin Powell, 36, was shot in his neck and chest, and later died at the University of Chicago Medical Center, police and the Cook County medical examiner’s office said. He lived in South Shore.

Jeremy Carothers, 39, was shot in the chest and back, and died at the same hospital, authorities said. He lived in the Park Manor neighborhood.

Another man, 36, was in critical condition at Christ Medical Center in Oak Lawn with a gunshot wound to the back, police said. The fourth man, 18, was shot in the shoulder and brought himself to University of Chicago Medical Center in good condition.

Two of the women were taken to St. Bernard Hospital in good condition, police said; they are a 36-year-old shot in the foot and a 35-year-old grazed in the foot.

The third woman, 33, declined medical treatment for a graze wound to the arm, police said.

A man who was having drink at the back bar in the rear of the building said later Sunday he heard at least five gun shots and bolted for the rear door.“People was running out the back and knocking over tables and dropping glasses,” said the man, who didn’t see what happened and asked not to be named.He said the bar is normally a mellow place, but that violence in the area isn’t unexpected.“It’s the wild, wild west on the South Side,” he said.Police said it is unknown whether the seven people were the actual targets or whether they were part of the fight inside.

No one is in custody, police said.
