Lavon Walker, 30, an anti-violence activist, died at a hospital after being shot Sunday on a street corner in Miami Beach, CBS News reports. The incident took place near the popular Miami Beach street Ocean Drive right before 7 a.m.
Three suspects were seen in a surveillance video speeding away from the scene of the shooting in a white Jeep Cherokee. Police are currently searching for them.
