Alex Murdaugh is on trial for the double murder of his wife and one of his sons. The defense's first witness, his surviving son Buster Murdaugh, testified that his father was "destroyed" and "just broken down" after learning of the shootings. He described his family as "close-knit" and said that disagreements were solved with civility. The defense is attempting to counter the prosecution's case and is expected to call more witnesses in the coming days.
