IMHO, Alex Murdaugh embezzled money at his firm. He killed his wife and son for insurance money to pay back what he had stolen. It did not work out. He then decided to kill himself so that his surviving son could collect his insurance. It did not work out.
Alex Murdaugh is a man for whom human life is just currency.

The prominent South Carolina lawyer whose life has unraveled in the months after his wife and son were fatally shot turned himself in to the police on Thursday after admitting that he had tried to stage his own killing earlier this month, but he maintained that he had no involvement in the killing of his family.
