Convicted killer Alex Murdaugh’s surviving son sat stone-faced at the Colleton County Courthouse Thursday as a South Carolina jury returned a guilty verdict on all charges against his father in the double-homicide trial.

Buster Murdaugh displayed little to no emotion in the aftermath of his father’s conviction for murdering his mother and brother at the family’s Islandton estate in 2021.

Sitting on the aisle a few rows behind his father, the 26-year-old’s left hand rested against the side of his face as each jury member confirmed their verdict, according to live courtroom footage.

As a handcuffed Alex Murdaugh was led from the courtroom, he said a few words to his lawyer but did not turn to look at Buster, who remained seated.

Alex Murdaugh’s conviction comes after a weekslong trial in which he stood accused of fatally shooting his 52-year-old wife, Maggie, and 22-year-old son Paul.

Buster actually testified on behalf of his 54-year-old father last Tuesday, when his testimony was supposed to punch holes in the prosecutors’ case.

His father cracked a smile as his surviving son took the stand, and even patted his son’s buttocks during a break in testimony.

Onlookers have paid close attention to Buster Murdaugh’s behavior as the trial dragged on, and he particularly stood out when he buried his head in his hand during his father’s cringeworthy testimony last week.  

Alex Murdaugh, a disgraced and disbarred legal scion, was also emotionless as he stood when his guilty verdict was announced — despite frequently being overcome with emotion throughout the proceedings, to the point where tears and snot ran down his face as he testified last week.

Sentencing is set for 9:30 Friday morning.
