LITTLE ROCK, Ark. — UPDATE- Police say they responded to a call at around 5:50 p.m. Tuesday about a woman laying on the ground next to the AutoZone. Police later learned that two men had been fighting over a weapon. When officers arrived on scene, they found 31-year-old Justin Foster unresponsive, with a man performing CPR on him.
