Alex Murdaugh was convicted Thursday of gunning down his wife and son after a panel of 12 jurors spent less than three hours deliberating.

The jury found Murdaugh guilty of two counts each of murder and weapons possession without posing a single question to the judge while weighing the case.

The panel’s decision came after they endured a grueling six-week trial and testimony from 76 witnesses – including Murdaugh himself.

Prosecutors argued that Murdaugh, 54, used a shotgun to kill his son, Paul, 22, inside a feed room attached to the dog kennels at the family’s estate, Moselle, and a rifle to execute his wife, Maggie, 52, June 7, 2021.

The disbarred attorney carried out the double slayings to stave off a devastating financial reckoning, Assistant Attorney General Creighton Waters told jurors.

The wealthy scion of a once powerful legal dynasty has admitted he’s a drug addict and thief who allegedly swindled his law firm and clients out of nearly $9 million – but denied killing his wife and son.

The most damning piece of evidence against Murdaugh is a cellphone video recovered from Paul’s phone in 2022 that places him at the murder scene with the victims four minutes before prosecutors say they were shot to death at 8:50 p.m.

For months, Murdaugh repeatedly told investigators, friends and his own family that he did not go to the dog kennels the night of the slayings. He claimed, instead, that he was napping at the main house perched on a hill then left to visit his mother in nearby Almeda at 9:07 p.m.

When he returned, he didn’t find them at the main house, so he drove to the kennels, where he said he came upon their mutilated bodies about 30 feet apart, checked their pulses and then called 911.

But GPS data from his Chevrolet Suburban revealed that he dialed 911 less than 20 seconds after he pulled up.

“Nineteen seconds. Is that enough time for a surprised human being to come across that scene, process what they are seeing, get out of the car, go over there, check both their bodies then call 911?” asked Waters in closing arguments.

“The reason why it’s so quick is because he knew exactly what scene he was going to find,” the prosecutor told jurors. Murdaugh claimed when he testified that he had checked their pulses while he was on the phone with 911.

Murdaugh admitted publicly for the first time when he testified to lying to investigators in three separate interviews about his presence at the kennels that night.

He claimed his oxycodone addiction made him paranoid of law-enforcement – although he had an exceptionally cozy relationship with local prosecutors and the surrounding sheriffs’ offices.

Three generations of the Murdaugh family served as the top prosecutor overseeing five counties in South Carolina’s Lowcountry for 87 years – a reign that ended when Alex Murdaugh’s late father Randolph Murdaugh III retired in 2005.
