Convicted killer Alex Murdaugh is demanding a new trial for the murders of his wife and son – claiming that mysterious “newly discovered evidence” has come to light since his conviction. In a bombshell motion filed on Tuesday, his attorneys Dick Harpootlian and Jim Griffin allege South Carolina Clerk of Court Rebecca Hill tampered with the jury at his trial – because she was driven by fame and a desire to secure a book deal. Details will be revealed at a press briefing at the South Carolina State House near the Court of Appeals in Columbia at 2.30pm local time. The latest development comes one week after the convicted killer lost some of his inmate privileges after he fed information to Fox Nation documentary “The Fall of the House of Murdaugh” without permission from prison officials. In it, Murdaugh’s only surviving son Buster also broke his silence to give his first TV interview. He insisted that he still believes his father is innocent but admitted that he may be a psychopath. Murdaugh is behind bars at the McCormick Correctional Institution where he is serving two life sentences for the 7 June 2021 murders of Maggie and Paul.
