Utah mom Kouri Richins is set to go on trial after being arrested and charged with her husband's death. She self-published a children’s book on grief called “Are You With Me?” after her husband died in 2022. She told a local TV station that writing it helped her and her three sons cope with the loss. Weeks later, she was shockingly arrested and charged with murder in her husband’s death. Richins has vehemently denied the allegations. Her lawyers hope to convince a jury that she is telling the truth when her trial begins Monday in Park City.

For years, social media companies have disputed allegations that they harm children’s mental health through the way they design their platforms, deliberately addicting kids and failing to protect them sexual predators and dangerous content. Now, these tech giants are getting a chance to make their case in courtrooms around the country, including before a jury for the first time. Some of the biggest players from Meta to TikTok are facing federal and state trials that seek to hold them responsible for harming children’s mental health

The trial has started for a man whose teenage son is accused of killing two students and two teachers at a Georgia high school in 2024. Lawyers gave opening statements Monday in the case against Colin Gray. Prosecutors say Gray gave his son, Colt, access to a gun and ammunition despite warning signs. They link that decision to the four deaths at Apalachee High School. Investigators say the 14-year-old planned the attack and brought a rifle in his backpack. Gray's attorney says his client wasn't told about the planning and timing of the shooting and shouldn't be held criminally responsible The trial is being held in Winder, where the shooting happened, with jurors from nearby Hall County.

Former CNN host Don Lemon has pleaded not guilty to federal civil rights charges in Minnesota. The veteran journalist is among several people accused in a Jan. 18 protest at Cities Church in St. Paul, where an Immigration and Customs Enforcement official serves as a pastor.

Lemon says he was chronicling the protest as an independent journalist. Prosecutors have accused him of joining a “mob.” Lemon says he will fight to defend his First Amendment rights. Nine people have been indicted in the case.

Alex Murdaugh's lawyers are asking the South Carolina Supreme Court to overturn his murder convictions. They argue that the trial judge's rulings and a biased court clerk prevented a fair trial. Murdaugh's lawyers told the justices at Wednesday's hearing that allowing evidence that Murdaugh stole from clients biased jurors into thinking he could be a killer, in a case that lacked any physical evidence linking him to the deaths of his wife and younger son. Even if the convictions are overturned, Murdaugh won't get out of prison. He is serving a 40-year federal sentence for stealing $12 million from clients.

Jurors in a landmark social media case that seeks to hold companies responsible for harms to children got their first glimpse into what will be a lengthy trial characterized by dueling narratives from the plaintiffs and the two remaining defendants, Meta and YouTube. At the core of the Los Angeles case is a 20-year-old identified only by the initials “KGM,” whose case could determine how thousands of other, similar lawsuits against social media companies will play out. She and two other plaintiffs have been selected for bellwether trials — essentially test cases for both sides to see how their arguments play out before a jury.

The world’s biggest social media companies face several landmark trials this year that seek to hold them responsible for harms to children who use their platforms.

TikTok and Snap, which were originally named in the lawsuit, settled for undisclosed sums. The companies will argue their case before a jury, and the outcome could have profound effects on their businesses and how they will handle children using their platforms.

Luigi Mangione spoke out in court against the prospect of back-to-back trials in the killing of UnitedHealthcare CEO Brian Thompson. The 27-year-old Mangione on Friday told the judge presiding of the New York case against him: “It’s the same trial twice. One plus one is two. Double jeopardy by any commonsense definition.” He made the remarks as court officers were escorting him out of the courtroom after the judge scheduled his state murder trial for June 8, three months before jury selection in his federal case.
