Sequita Thompson, the grandmother of slain gunshot victim Stephon Clark, let out an emotional plea for justice during a recent press conference.

Thompson detailed the moment she heard her grandson killed in her backyard by police, hearing the “boom, boom, boom, boom” of 20 gunshots before grabbing her 7-year-old granddaughter and crawling away from from the shower of bullets while inside her home.

“My great-grandbabies don’t have their daddy,” she cried, barely able to stand. “Why didn’t you shoot him in the arm? Shoot him in the legs? Send the dogs? Send the Taser?”

“I just want justice for my grandson.”
