Disgraced South Carolina attorney and convicted murderer Alex Murdaugh was sentenced Friday morning to two consecutive life terms for the grisly 2021 murders of his wife and son.

The once-prominent legal scion was stone-faced as he learned his fate at the Colleton County Courthouse in Walterboro, just hours after the jury returned the guilty verdicts following less than three hours of deliberation.

“I’m innocent,” Murdaugh, 54, said when given the chance to address the court.

“I would never hurt my wife, Maggie, and I would never hurt my son Paw Paw.”

His surviving son, Buster, 26, also remained emotionless, and took occasional sips from a plastic water bottle. The defendant’s younger brother, John Marvin Murdaugh, seemed more emotional, and blinked frequently while clenching his jaw.

In his argument for the maximum sentence, prosecutor Creighton Waters called Murdaugh a “cunning manipulator” who “placed himself above all others.”

“No one who thought they knew this man, thought they were close to this man, knew who he was, and your honor, that is chilling.

“And I’ve looked in his eyes, and he liked staring me down as he would walk by me during this trial and I could see the real Alex Murdaugh when he looked at me.

“The depravity, the callousness, the selfishness of these crimes are stunning, the lack of remorse and the effortless way in which he lies including sitting over there in the witness stand. He should never be allowed to be among free, law-abiding citizens again.”

The sentence was also read after a long speech from Judge Clifton Newman, who said it was “heartbreaking” to witness his former colleague’s spectacular fall from grace as it played out in the media over the last year and a half.

“When will [the lies] end?” Newman asked Murdaugh, who previously admitted on the stand that he frequently deceived his partners and family in the throes of his drug addiction, and continued to lie to police throughout the investigation into Maggie and Paul’s deaths.

After Murdaugh again repeated in court that he would not hurt his wife and son despite the conviction, the judge told him: “It may not have been you … it might have been the monster you had become. You take 50, 60 opioid pills a day, I’ve seen that before, the person before me is not the same person. But it is the same individual.”

The jury deliberated for less than three hours before coming to the verdict Thursday night — following six weeks of wild testimony that chronicled the unraveling of a powerful legal dynasty.

“I am surprised,” Joseph McCulloch Jr., a Columbia, South Carolina, lawyer and close friend of the Murdaughs, said of the verdict.

“I expected much more deliberation after six weeks of testimony and all that evidence. I thought it would end with a hung jury.”

The lurid saga, which garnered national attention, started on June 7, 2021, when Maggie Murdaugh, 52, and her son Paul, 22, were shot dead by the kennels at the family’s Islandton hunting lodge.

During their four weeks of testimony, the state’s attorneys argued that Murdaugh, the heir to a storied legal dynasty, killed his wife and son to cover up his financial crimes that were on the verge of being discovered.

The defense, however, painted a starkly different image of Murdaugh as a fumbling, guilt-ridden patriarch in the talons of drug addiction.

One of the key moments in the closely watched trial was the content of an interview between Murdaugh and investigators three days after the killings.

Prosecutors played the audio of the exchange in court, claiming that Murdaugh clearly sobbed “I did him so bad!” when shown images of Paul’s mangled body.

However, Murdaugh’s defense team countered the state’s argument with a slowed-down version of the recording, which they argued proved that Murdaugh actually cried, “They did him so bad!”

When Murdaugh took the stand in his own defense, he admitted to lying to police about his whereabouts the night of the murders.

Though he initially maintained that he was visiting his mother, who had advanced Alzheimer’s disease, at the time of the killings, Murdaugh testified that he was indeed the voice captured by Paul in a Snapchat video at 8:45 p.m.

The clip was recorded just five minutes before experts believe the young man and his mother were gunned down.

“The evidence is overwhelming but I can’t believe the jury was brave enough to convict him,” an ex-friend of the family, John Wright, said of the conviction.

“I honestly didn’t think they would. Everyone knows these guys, and in addition to that, they had a lot of influence here. I thought the jury might be more reticent or fearful about convicting him.”

A lawyer for the family of the Murdaugh family’s late housekeeper, Gloria Satterfield, told The Post he was glad that Murdaugh “now drinks from the same cup of justice as every other murderer.”

Satterfield, 57, died in 2018 after Murdaugh said she tripped over his dogs, according to the family’s lawsuit. Hampton County Coroner Angela Topper said the death was suspicious, though no autopsy was conducted.

One-time murder suspect OJ Simpson even chimed in on the captivating case, stating in a Twitter video that he felt the Murdaugh trial could have ended with the same not-guilty verdict as his own.

“Do I think it’s more likely that he did it? Yes. But more likely equals reasonable doubt,” said the former football star, who was acquitted in 1995 of the stabbing deaths of his ex-wife, Nicole Brown, and her friend Ron Goldman.

In addition to the murder convictions, Murdaugh faces trial over dozens of alleged financial crimes that could total over 700 years behind bars, Law & Crime reported.
