Investigators still do not know why Stephen Paddock shot and killed 58 people during an outdoor music festival in Las Vegas last October, CBS News reports. In a press conference Friday, authorities conceded that three months of investigation had not yielded any findings on Paddock's motivations, though Clark County Sheriff Joe Lombardo did emphasize that Paddock acted alone and that his girlfriend — who was at one point suspected of helping him — would not be charged with any crime.

During the press conference, Lombardo also discussed a newly released 81-page report that examined Paddock's actions in the months leading up to the shooting, which was the deadliest in modern American history. The evidence indicated Paddock had been planning an attack for a while; investigators found he purchased over 50 firearms in the 12 months leading up to the shooting, and that he had studied the response strategies of various law enforcement departments.

Lombardo noted that "disturbing" internet searches Paddock had conducted indicated he may have considered carrying out the attack at other concerts or at beaches in California, CBS News reported. Investigators also found child pornography on Paddock's computer.

Pope Francis made what has been described as an "almost revolutionary" decision, the Vatican announced Saturday, expelling Theodore McCarrick from the priesthood. The decision came after an expedited Vatican trial found the former cardinal and archbishop of Washington guilty of sexually abusing three minors and harassing adult seminarians and priests.

This is believed to be the first time the church has defrocked a U.S. cardinal. McCarrick is also the highest-ranking church official to be dismissed for sexual abuse. "Bishops and cardinals are no longer immune to punishment," Kurt Martens, a professor of canon law at the Catholic University of America, told the The New York Times.

Allegations against McCarrick reached church officials as early as 2000, CNN reports, just months before he became a cardinal. After the accusations became public in 2017, McCarrick resigned from the College of Cardinals but denied he had any recollection of the incidents. Francis ordered a Vatican investigation into the matter, as did the Archdiocese of New York, where several of the alleged incidents occurred. The probes found the accusations to be "credible and substantiated."

The news comes just ahead of this week's meeting of top Catholic officials from around the world, who will gather in Rome to discuss the church's sex abuse crisis. The summit is the first of its kind. Tim O'Donnell

Six people were killed, including a shooting suspect identified by authorities as a man named Gary Martin, in a workplace shooting at a manufacturing plant in Aurora, Illinois, on Friday afternoon.

Martin was a 15-year employee of the Henry Pratt Company and was scheduled to be let go from his job Friday. In addition to fatally shooting five people, he wounded six police officers, all of whom are in stable condition. Though initial reports said the suspect was taken into custody, Aurora Police Chief Kristen Ziman said he was killed in an exchange of gunfire with police.

Illinois Sens. Dick Durbin (D) and Tammy Duckworth (D) both tweeted their thanks to first responders and said they were monitoring the situation. "My heart hurts for the victims, their families, the brave first responders, Aurora, and all of Illinois right now," Duckworth wrote in a follow-up post. "Our nation's epidemic of deadly gun violence is a real national emergency." Bonnie Kristian

White House Press Secretary Sarah Huckabee Sanders has been interviewed by Special Counsel Robert Mueller's team, Sanders said in a statement Friday.

"The president urged me, like he has everyone in the administration, to fully cooperate with the special counsel," Sanders said. "I was happy to voluntarily sit down with them." Sanders did not comment on the content of the conversation, and CNN reports, citing unnamed sources, the White House did not immediately accede to Mueller's request for the interview.

Sanders' interview took place in the fall of 2018, around the time Mueller's investigators spoke with other current and former senior administration figures, including then-Chief of Staff John Kelly, former White House Communications Director Hope Hicks, and former Press Secretary Sean Spicer.

Daisy Ridley, John Boyega, and Oscar Isaac may have just taken their last steps in a larger world.

Director J.J. Abrams on Friday announced that Star Wars: Episode IX, which is being billed as the conclusion of the franchise's Skywalker saga, has officially wrapped production. "There is no adequate way to thank this truly magical crew and cast," Abrams wrote, posting a photo of the film's main three stars hugging on set. "I'm forever indebted to you all."

Boyega wrote that this is "the end to a chapter of my life that I couldn't be more thankful for," also thanking Abrams for "making my dreams come true."

The photo is only the second glimpse of Episode IX, following a picture taken in the Millennium Falcon that Abrams tweeted when production began in August. The photo posted Friday reveals that Episode IX will feature scenes on a desert planet, perhaps Luke Skywalker's home, Tatooine, or Rey's home, Jakku. The photo also shows Rey and Finn sporting new hairdos, while Poe seems to be rocking some suspenders.

With 10 months to go until Episode IX is released, Lucasfilm still hasn't yet revealed the film's official title, but that announcement could be imminent. The title of The Force Awakens, after all, was announced shortly after production wrapped in 2014. Then again, the title of The Last Jedi wasn't announced until four months after production wrapped.

In addition to the returning cast, Episode IX will feature Billy Dee Williams reprising his role of Lando Calrissian, as well as a posthumous appearance by Carrie Fisher as Leia Organa using footage shot for The Force Awakens. The film hits theaters on Dec. 20. Brendan Morrow

Roger Stone may need to cut down on his Infowars appearances.

U.S. District Court Judge Amy Berman Jackson on Friday issued a gag order in the trial of the former adviser to President Trump, saying Stone must "refrain from making statements to the media or in public settings that pose a substantial likelihood of material prejudice to this case," Politico reports.

Stone was arrested last month as part of Special Counsel Robert Mueller's investigation, and he pleaded not guilty to charges of witness tampering, lying to Congress, and obstruction, The New York Times reports.

But that hadn't slowed down Stone's media appearances, and he jumped on Alex Jones' InfoWars two times within a week after his arrest. This prompted Jackson to warn him earlier this month that he must stop acting like he's on "a book tour."

Axios reports that the gag order prevents Stone from making any comments "within the vicinity of the courthouse." But Politico notes that the gag order only prevents him from talking about his case, and Jackson says he can continue talking about "foreign relations, immigration or Tom Brady" to his heart's desire.

Police have arrested two potential suspects in connection with the alleged assault of Empire star Jussie Smollett, ABC News reported on Friday.

Chicago police told ABC that two men were arrested on Wednesday at the airport, with detectives having "probable cause that they may have been involved" in the alleged assault. The suspects have not yet been charged with a crime, however.

Authorities also told ABC that the suspects "have a relationship with" Smollett but did not offer specifics. According to CNN, they are two Nigerian brothers, and CBS 2 Chicago reports they have worked as extras on Empire.

This development comes after two local news stations reported Thursday that investigators now believe the attack on Smollett was staged, per Variety. But chief police spokesperson Anthony Guglielmi said that there is "no evidence to say that this is a hoax" at this time, USA Today reports. One of the Thursday reports had also said investigators believe Smollett staged the attack because he was being written off Empire, something 20th Century Fox denied in a statement, calling the notion "patently ridiculous."
