Grant and Stoudemire were involved with Mothers/Men Against Senseless Killings. The two were "occupying" the corner for MASK, engaging the community and offering information on the organization, when they were shot.
"It is terrifying. It is heartbreaking. I haven't slept because I am trying to figure out how we can stop this," MASK founder Tamar Manasseh told the Chicago Sun-Times. "Who's next? I just keep thinking, 'Who's next?'"
Grant was a mother of four, and Stoudemire was a mother of three.
MASK returned to the spot Sunday, and this time people left candles and flowers as tributes to the women, The Washington Post reported.
"WE AREN'T GOING ANYWHERE," Manasseh wrote on a GoFundMe page MASK established. The group is raising reward money for information "that will bring these mother killers to justice."
