A jury has found disgraced South Carolina attorney Alex Murdaugh guilty of brutally murdering his wife and younger son at the family's property in 2021.
The jury reached the verdict after deliberating for nearly three hours Thursday after hearing five weeks of testimony from more than 70 witnesses -- including Alex Murdaugh himself, who denied the murders but admitted to lying to investigators and cheating his clients.
He was found guilty on all four counts -- two counts of murder and two counts of possession of a weapon in the commitment of a violent crime.
Judge Clifton Newman said the court would reconvene Friday morning at 9:30 a.m. local time for sentencing. Alex Murdaugh faces 30 years to life in prison for the murder charge.

The verdict proved that "no one in society is above the law," South Carolina Attorney General Alan Wilson told reporters outside the courthouse following the verdict.
"It doesn't matter how prominent you are -- if you do wrong, if you break the law, if you murder, then justice will be done in South Carolina," lead prosecutor Creighton Waters told reporters.
The jury visited the family's estate, Moselle, on Wednesday to see the crime scene ahead of deliberations. The bodies of Margaret Murdaugh, 52, and Paul Murdaugh, 22, were found dead from multiple gunshot wounds near the dog kennels at the family's estate in June 2021, authorities said.
Alex Murdaugh, who called 911 to report the discovery, was charged with their murders more than a year later.
MORE: Key moments from Alex Murdaugh double murder trialProsecutors claim that Alex Murdaugh, who comes from a legacy of prominent attorneys in the region, killed his wife and son to gain sympathy and distract from his financial wrongdoings.
Meanwhile, the defense has portrayed him as a loving husband and father, and argued that police ignored the possibility that anyone else could have killed them. While testifying, Alex Murdaugh blamed lying to investigators on his addiction to painkillers, which he said caused "paranoid thinking."
During his nearly four-hour closing argument on Wednesday, Waters declared that Alex Murdaugh was the only person "who had the motive, who had the means, who had the opportunity to commit these crimes" and that his "guilty conduct after these crimes betrays him."
Waters told the jurors that credibility is important and painted Murdaugh as someone good at lying who was used to anticipating how jurors read things.
"This is an individual who was trained to understand how to put together cases, complex cases. He's been a prosecutor," Waters said. "He's given closing arguments to juries before. So, when you have a defendant like that, be thinking about whether or not this individual is constructing defenses and alibis."
Waters recounted a timeline investigators put together of the three Murdaughs' cell phones the day of the murders, including a video from Paul Murdaugh's phone that placed Alex Murdaugh at the kennels minutes before authorities believe the shootings occurred -- contradicting earlier statements in which he said he was never at the kennels.
Waters said the last time Alex Murdaugh saw his wife and child alive was the "most important thing" he could have told law enforcement.
"Why in the world would an innocent, reasonable father and husband lie about that and lie about it so early?" Waters said.

Defense attorney Jim Griffin recounted to jurors during his closing argument on Thursday the multiple missed opportunities, pointing out evidence that investigators did not collect including foot imprints, fingerprints and DNA. He also replayed videos in which prosecution witnesses testified about how much Alex Murdaugh loved his wife and son.
"Which brings us to the question, why?" said Griffin, discounting the state's proposed motive that years of lies and theft were about to catch up to Alex Murdaugh and the murders were a way to divert attention.
"Even if the financial day of reckoning was impending, if it was right there, he would not have killed the people he loved the most in the world," he said. "There's no evidence that he would do that."
Griffin also addressed that Alex Murdaugh admitted to lying to investigators about his alibi the evening of the shootings.
"I probably wouldn't be sitting over there right now if he did not lie. But he did lie, and he told you he lied," Griffin told the jurors."He lied because that's what addicts do. He lied because he had a closet full of skeletons and he didn't want any more scrutiny on him."
MORE: Juror removed from Alex Murdaugh murder trial for talking about case to friendsIn the months following his wife's and son's murders, Alex Murdaugh resigned from his law firm, which sued him for allegedly funneling stolen money from clients and the law firm into a fake bank account for years. He also said he entered a rehab facility for opioid addiction.
Alex Murdaugh faces about 100 other charges for allegations ranging from money laundering to staging his own death so his surviving son could cash in on his $10 million life insurance policy. He was also charged for allegedly misappropriating settlement funds in the death of his housekeeper, Gloria Satterfield, who reportedly died after a falling accident at the Murdaugh family home in February 2018.
