Alex Murdaugh was back on the stand in his own defense Friday. The prosecution continued its cross-examination, and Murdaugh testified that he believes his wife and son were killed as payback for his son Paul's boating accident that left his friend Mallory Beach dead. Will the jury buy Murdaugh’s theory? Attorneys Eric Bland, and Mark Geragos discuss. #AlexMurdaugh #trial #SouthCarolina
