He had diarrhea and, it’s just, he couldn’t control it. When I say diarrhea I am not talking about a restroom, I am talking about the car and his pants.”As the video of Marvin’s testimony went viral online, social media users pointed out that “only a sibling” would make such comments in public:LegallyDirtyBlonde@LDBlondePod@theshamingofjay Only a sibling would do this 🤣57@theshamingofjay Only a sibling would do this 🤣John Marvin also testified about the night of Paul and Maggie Murdaugh’s murders and opened up about seeing the crime scene for the first time:“I saw blood, I saw brains, I saw pieces of skull. It was terrible.”He also said that he loved his nephew and wanted to collect his remains and clear the scene to honor Paul’s memory:“It felt like it was the right thing to do. I felt like I owed him, and I started cleaning, and I promise you no mother or father or aunt or uncle should ever have to see or do what I did that day. It's the hardest thing I've ever been through in my life.”Marvin revealed that investigators told him that they knew Alex Murdaugh was behind the murders because there were bloodstains on his T-shirt:“They told us that it was covered in blood. They went so far as to tell me on the police bodycam that he takes his shirt and wipes his face and that's how they knew that Alex was at the scene, and that he was the one.”Joseph Leonard | WSAV@JLeonardNewsJohn Marvin testifies #AlexMurdaugh never told him he had been at the scene minutes before the killings.
