Yeah I think she tried to flippantly claim there may have been a police car. It was a homicide, there would have been a plethora of LE cars, a hive of activity. If she wants to carry on playing this game it will end the same way it has for all the other co-conspirators who have failed to grasp the basic concept that testimony has to be plausible.
DA will get up on the stand and spout a whole bunch of garbage and will get convicted. Then WA will be charged, spout the same rubbish, followed by HA. Once they're all rotting in prison, I wonder if any of them will reflect on their behaviour, actions and strategy surrounding their arrests and trials.
At this stage, the only thing that can save them from doing less than 30 years is co-operation. Are their lawyers telling them this? I would love to be a fly on the wall.
