Alex Murdaugh's eldest and only surviving son, Buster Murdaugh, "has nothing to do" with a new investigation into the 2015 death of his high school classmate, Stephen Smith, according to the Smith family's new legal team

"Buster is a victim. He lost a mother, a brother, and now his father's in jail," attorney Eric Bland said during a Monday press conference. "Buster, as we know, has nothing to do with this. And whatever is mentioned in the records, that's what investigators are going to look at. But we have no knowledge at all about Buster or the Murdaughs having anything to do with this right now. We're starting with a fresh set of eyes."

Smith, 19, died in July 2015 in what police initially described as a hit-and-run along a rural road just miles from the Murdaugh family's hunting estate, Moselle, in Hampton County, South Carolina

Members of the public have expressed skepticism about the conclusions reached about Smith's death after Alex Murdaugh was found guilty of murdering his wife, Maggie, and youngest son, Paul, at Moselle on June 7, 2021.

"We've not mentioned Buster's name one time," attorney Ronnie Richter said during the Monday press conference. "This is not about Buster Murdaugh. This is about Stephen Smith. It's about trying to get answers to questions that his mother desperately needs answers for. So there's no reason to discuss Buster at all, and there's no comment to make back to Buster at all. Were going to find out, God willing… what was Stephen Smith’s true cause of death"
