Officers located a second victim at the scene who was transported to the hospital for non-life-threatening injuries. They believe this was a targeted attack.
"We don't have any indication that this was celebratory gunfire that some people witnesses during July 4th. We believe this was targeted not toward the 6-year-old boy but we believe this was not random," said Officer Rueca.
