Again, why didn't they just say mom did it all? Mom could have gone to the park for whatever. Doesn't she spend a lot of time in the park?
Why did they put themselves into the car?
Again ..... they were trying to think of some
innocent reason for the family car to be the neighborhood drug dealer's place of business at 11:30 at night. "Oh, yeah, mom goes down to the park late at night where the drug dealer hangs out all the time. She spends a lot of time there late at night." Uh...... that doesn't sound all that innocent, y'know?
This is an interesting exercise. If they were going to claim that mom was down there at the park by herself, they couldn't have made any further claims. They couldn't have claimed it was a road rage case. Because how would they know, if neither of them was with mom at any point? They could only claim that mom drove home and got shot right in front of the house. And then they would have to explain how Brandon was johnny-on-the-spot with his own gun, firing back, when he was supposedly innocently sleeping at home. By the time he heard the gunfire, got dressed, retrieved his gun from gramma's drawers, and made it downstairs and outside, the shooting would have already been over and the silver car gone. But he did fire back -- so he needed an explanation as to how he was out front firing his gun so quickly.
Also, possibly the daughter texted somebody while she and Brandon were out looking for EN, or while EN was following them. "Hey, BFF, we just got shot at! OMG! Just like in the movies!" She would know she's going to have to explain that.
Or, they both had their cell phones, and they knew cell phones can reveal your location by pinging cell towers.
Or, they knew there were surveillance cameras around the neighborhood. They needed a story that had sis in the car at some point, in case sis was caught on camera, and bro in the car at some point, in case bro was caught on camera.
Lots of reasons they may not have been able to blame it all on mom.
