Several of the jurors who served on Alex Murdaugh's 6-week murder trial are speaking out.  And they all claim an interrupted Snapchat video Paul Murdaugh was filming at the scene of the double murders was the critical piece of evidence. And it "sealed the deal" in their decision to convict the South Carolina scion in the murders of his wife and youngest son.

On March 3 Murdaugh was sentenced to life in prison for the murders of Maggie and Paul Murdaugh. And his attorneys have already announced they will appeal the conviction.

The Murdaugh trial and Alex’s conviction for killing his wife and son have gone viral and the saga of family legacy, entitlement, and murder is captivating a global audience.

Alex Murdaugh once considered a respected member of the legal community, and high society in South Carolina has been found guilty of a monstrous crime. 

Kennel video had Alex’s voice

Some of the jurors who convicted him made an appearance on TODAY. And explained why it only took 45 minutes to convict him.

The Snapchat video Paul Murdaugh filmed at the dog kennels on the Murdaugh family property contained audio of Alex Murdaugh yelling at one of the dogs just minutes before the time of the murders.

Alex Murdaugh has been widely criticized for taking the stand in his own defense. Juror Gwen Generette said it convinced her of his guilt.

Generette said, "When he got on the stand, I was like, 'OK, so it was him. ‘I don't know him, so I never knew his voice, but I realized it was him in the kennel video, and that just kind of sealed the deal."

The jurors found Alex Murdaugh’s emotional testimony unconvincing. And they believed there were multiple factors that contributed to the murders, including Murdaugh's alleged financial crimes.

The verdict has brought some closure to the Murdaugh family's tragic story, but it has also raised more questions about other deaths tied to the family.
