7/11 Hold-up

Patrolman Jones is clearing an accident. In the traffic backup are people waiting to rob the close by 7-11. They leave the driver and walk to the 7-11. Patrolman Jones clears the accident, turn around in the 7-11’s lot and goes off shift. Why shoot the delivery man, steal his truck, and rob the store of nothing?
Detective Rage can’t decide what they took. Two old fishermen are bar hoping around the warehouse that loaded the truck.
HLS decides to break into Rage’s house and take her prisoner. They may have a problem; patrolman Jones is visiting.
All this over what?
