Richard "Alex" Murdaugh was sentenced to life in prison on Friday for killing his wife and son in what prosecutors said was an attempt to hide his drug addiction and theft of millions of dollars.
He was found guilty on Thursday on two counts of gunning down his wife Maggie, 52, and youngest son, Paul, 22, on their family estate on 7 June 2021. The jury took only three hours to reach their decision after a five-week trial.
At a hearing on Friday, Circuit Court Judge Clifton Newman sentenced Murdaugh to prison for the remainder of his life, with terms for both murders to run consecutively. It was the sentence requested by prosecutors, who did not seek the death penalty.
The 54-year-old's lawyers said they would appeal his conviction.
Murdaugh had faced a minimum of 30 years in prison for each of the two counts of murder under South Carolina law, as well as up to 10 years for two related firearms charges.
Who is Alex Murdaugh?
The case has drawn intense media coverage given Murdaugh's family's immense political power in and around Colleton County — an area west of Charleston in the US state of South Carolina — where the trial took place.
For decades until 2006, family members served as the leading prosecutor in the area, and Murdaugh was a prominent personal injury attorney in the state.
Judge Newman criticised what he described as Murdaugh's "duplicitous conduct" throughout the trial, and said his actions were especially troubling given that the Murdaugh family had "controlled justice in this community for over a century."
He said he did not question the state's decision not to seek the death penalty, but he noted that Murdaugh family members had "been prosecuting people here in this courtroom and many have received the death penalty, probably for lesser conduct."

"I know you have to see Paul and Maggie during the nighttime when you attempt to go to sleep," he said. "It might not have been you (who killed them). It might have been the monster you become."
Murdaugh, dressed in prison garb, professed his innocence again on Friday.
"I'm innocent. I would never hurt my wife Maggie and I would never hurt my son, Paw Paw," he said, using a nickname for Paul, minutes before the judge delivered his sentence and he was escorted from the courtroom in handcuffs.
Throughout the trial, prosecutors portrayed Murdaugh as a serial liar and argued that only he had the means and the opportunity to commit the murders. Prosecutors said he fatally shot his wife and son to distract from an array of financial misdeeds, including the theft of millions of dollars from his law partners and clients — money used to feed a years-long addiction to opioids and support an expensive lifestyle.

They floated alternative theories, with Murdaugh testifying last week that he believed someone angry over a deadly 2019 boating accident involving Paul likely sought revenge on his son.
Murdaugh plans to appeal the verdict all the way to the US Supreme Court, his lawyers said on Friday, arguing that the judge's decision to allow testimony about all of his financial misdeeds unfairly undermined his credibility with the jury.
"They would never, ever, ever acquit him after that," Dick Harpootlian told a news conference.
Among the prosecution's strongest evidence was Murdaugh's admission that he had lied about his alibi, telling investigators he wasn't at the dog kennels where the murders took place on the family estate. Murdaugh changed his account after the jury listened to audio evidence placing him at the crime scene minutes before the murders occurred.

"There had to be quite a bit going through your mind," Judge Newman said, and yet he noted that Murdaugh had testified to that day being like any other, that he had been enjoying life with his wife and son.
"Not credible, not believable," the judge said.
