1) The victims never left the parking area in the plaza. The police vehicle was out on the street and responded immediately after the officer put the DUI suspect in his vehicle.
2) Apparently they did not because they returned to the Gate when they found JD had been shot.
3) LE did search the bushes but didn't do so because MD failed to report the shooting and did not tell them until after 3pm the following afternoon. They can't search if they were only aware of what happened from the witnesses who never saw a shotgun. Shotguns are very difficult to miss when someone steps out of a car and aims one at another person. Witness said there was no gun they could see. You would see a shotgun. In MD's first interview he admits he was not sure what it was, a gun barrel, a pipe.....he never said he actually saw a gun, just that he thought it was a shotgun.
4) The police vehicle was across the street with a stopped DUI driver he was in the process of arresting. The officer was the first to arrive at the Gate and the SUV was already parked back at the Gate.
Hope that helps. jmo
