MORE food for thought.
Damon never appeared to be the 'caring father' up until,,,,,,,, it looked like the Prosecution might lose their case.
Who would suffer if they did? The DA. Might lose his re-election. So, where is all the VD's money (new house) coming from ?
Gee, DA, powerful position, lot's of bribe money, organized crime money, hush hush money, etc.
So, he pays Brenda some money, arranges for Damon to kill DW. DW dead before trial over, it's over. DW will be seen as guilty, case closed. DA wins.
Damon gets light sentence due to temporary insanity, grieving father ( and the DA,prosecutor will be already on his side), and no futher investigations into Daneille's death.
EVERYBODY (except DW and Danielle, and the San Diego citizens, and the US system of JUSTICE) WIN !
