Authorities say that through the interviews, they learned that the teenagers went to the smoke shop with the intent to assault or fight the victim in retaliation for a friend of theirs being stabbed several days ago.
According to the criminal complaint, the trio of teens collaborated with a group likely from outside the Harrisburg area to assault the person they believe had stabbed their friend.
Police say on November 13, while the group was looking for the person responsible for the stabbing, they located a similar vehicle outside the Derry Smoke Shop.
Upon arrival, the group began an altercation with those who were smoking outside the smoke shop, according to the criminal complaint.
Authorities say that the shooting is not shown on video, but there is an obvious reaction on screen as people run away.
Police did not note which of the trio pulled the trigger, and all three are facing charges for their roles in the incident.
