Two officers each fired 10 shots at Clark, though it was not immediately clear how many times he was struck.Helicopter and police body camera video released by the department Wednesday shows the moment the two officers gun down Clark in a hail of bullets. “The only thing that I heard was pow, pow, pow, pow, and I got to the ground” inside the home, Sequita Thompson, Clark’s grandmother, told the Bee. Thompson crawled over to her 7-year-old granddaughter and told her to lie on the ground as the shots went off. After her family was safe and police began to interview her, Thompson looked out of a window where she saw Clark’s body in the backyard.“I opened that curtain and he was dead,” Thompson told the publication. “I started screaming.”Police said they believed Clark was armed with a gun, though no weapon was found. The department then said they believed Clark was carrying a tool bar used to smash windows. Instead, they found only a cell phone on him.A cinder block and a piece of aluminum were found near the broken sliding door of a neighbor’s home, and police said one of those items might have been the tool bar that the helicopter crew reported seeing.Clark leaves behind his two sons, ages 1 and 3. A GoFundMe has been set up to help Clark’s grandmother pay for his funeral.Clark’s older brother, 25-year-old Stevante, told HuffPost the 3-year-old has been asking where “daddy” is.“Right now we’re just comforting each other, loving each other and praying,” Stevante Clark said of the family. “We’re praying for not only justice, but praying that the truth comes out regarding who he really was, not no petty thief.”The younger Clark wasn’t the type of person who would commit a robbery, his brother said. Stephon liked to dress nice, and in their last conversation with each other told his older brother he was getting his nails done, Stevante said. “He’s not the character [police] portray him to be,” he said. “He grew up. I could see it in him. He was a great person. He was my role model.”“He would never want to leave his kids,” Clark’s girlfriend of five years, Salena Manni, told ABC 10.“I have to wake up every morning to my kids asking me, ‘Where’s Daddy? Let’s go get Daddy,’” Manni told ABC-10. She said she tells them, “Daddy’s always in our hearts forever. Don’t forget that.” The older Clark echoed that sentiment, and said he wants to set up a trust fund for his young nephews.“I want people to know all he cared about ― more than anything else in life ― was his children. His children meant most to him.”Stephon Clark (right) was in his own backyard when he was fatally shot by police. Clark is pictured in this photo with his brother, Stevonte Clark.
