Prosecutors produced no direct evidence linking South Carolina attorney Alex Murdaugh to the killings of his wife and son, yet a jury took less than three hours to convict him. Legal experts say that is thanks, in large part, to the defendant himself. Observers say Murdaugh did himself no favors by taking the witness stand, where he admitted to stealing money from clients and lying to investigators about being at the kennels with his wife and son Paul shortly before their killings. Murdaugh maintained his innocence on Friday before being sentenced to life in prison without parole for the shooting deaths of his 22-year-old son and 52-year-old wife.
