Jack had been following the group at arms length since they had left the school. He had been scouting the school for the past two days coming across it by chance on a supply run. It was his luck that they had left when they had because he didn't know exactly how much time he had left to lie in wait to approach them. Witnessesing everything that had gone down in the past few minutes the gunshots the death of the man and what he assumed was his child had shook Jack to his core for a moment. Recollecting himself he aimed the M4 towards the position of the shooter and began firing shots in an attempt to suppress the bullets being fired at the group. He saw the shooter retreat from their position and flee into the woods. Jack then began taking timed headshots on walkers to minimize the damage done to the people he hopes will help him out with his little problem. Hitting the magazine release be quickly loaded a fresh mag and moved out of his position continually shooting any walkers that came across his path.
