The corner of 75th and Stewart is a special place on the South Side of Chicago. It’s the place where Tamar Manasseh decided she would do something to stop gun violence in Chicago.

She started a group a few years ago called Mothers and Men Against Senseless Killings, or MASK. Volunteers gather on the corner almost everyday of the summer to feed kids and have activities. The hope is that building community will bring an end to shootings in the area.

But last Friday, two women out on the corner were shot and killed there: Chantell Grant, who regularly brought her kids to MASK activities; and Andrea Stoudemire, who was a neighbor with a reputation for being fiercely protective of women in the neighborhood.
