Alex Murdaugh’s older brother is convinced the convicted murderer is still lying over the brutal slayings of his wife and son. “He knows more than what he’s saying,” Randy Murdaugh, 56, told the New York Times of his drug-addicted, serial-lying brother who still denies gunning down wife Maggie, 52, and son Paul, 22. “He’s not telling the truth, in my opinion, about everything there.” Randy’s admission is in sharp contrast to a claim by his 54-year-old brother’s defense team that the whole family was “more convinced” of the disgraced legal scion’s innocence after his six-week trial.
