About

John Marvin Murdaugh testified for the defense about his observations of Alex Murdaugh and other family members, the family's movements around June 7, and events following the killings. He traced vehicle exchanges, said Paul appeared normal when he last saw him, and described Alex's calls and distraught condition afterward.

He also addressed the investigation's immediate aftermath. After law enforcement released the kennel scene, he attempted to clean biological material near the feed room. He used Buster's phone to help locate Maggie's phone, participated in searches of Moselle and Almeda, and described differing accounts investigators gave about where a coat was recovered.

His testimony covered Alex's opioid withdrawal, parking locations at Almeda, and his interpretation of a disputed recorded phrase as "they did him so bad." He told the jury that SLED personnel had said Alex's white shirt was covered in blood and that body-camera footage showed Alex wiping his face with it. He identified those statements as information relayed by investigators, not as his own observations.

On cross-examination, John Marvin initially described the family as fully cooperative, then agreed that Alex had lied by failing to tell investigators he had been at the kennels before the killings. He answered questions about vehicle and key access, investigative searches and interviews, and an alleged blue-jacket discussion that he repeatedly said he did not recall. He also qualified his interpretation of Alex waking in apparent fear during travel from detox to rehabilitation and acknowledged that he had not heard Alex's conversation with Jeannie Seckinger.
