Gabby Petito's body believed to have been found in Grand Teton National Park, FBI says

Federal authorities have discovered the remains of a body they believe to be Gabby Petito, 22, a blogger whose mysterious disappearance has fueled national intrigue and a cross-country effort to solve the complex and increasingly bizarre case. The FBI made the announcement on Sunday, explaining law enforcement had combed through a camping area in Wyoming's Grand Teton National Park and found human remains that appear to be Petito. Authorities will conduct a full forensic review to verify the remains, according to the FBI.

Petito went missing while on a cross-country trip with her fiancé, Brian Laundrie, 23. She was last seen in Grand Teton National Park in late August. Laundrie returned home alone on Sept. 1 from the couple's weekslong trip, only to disappear himself last week.

Inspiration4 crew splashes down after historic trip to space

To the SpaceX Inspiration4 crew, welcome back to Earth. Days after the four "non-astronauts" made history by launching into space, the trip ended Saturday with a splashdown in the Atlantic Ocean off the coast of Florida. "Thanks so much, SpaceX," said tech billionaire Jared Isaacman. "That was a heck of a ride for us and we're just getting started." The mission was paid for by Isaacman, who promoted the flight as a massive fundraising effort for St. Jude Children's Research Hospital. Rather than just climbing to the edge of space and returning to land in less than an hour as Virgin Galactic and Blue Origin did, Inspiration4 circled the Earth for three days and did so in a higher orbit than the International Space Station.

Experts confident FDA will soon back booster shots for broader population

Dr. Anthony Fauci defended the Biden administration's booster rollout plans on Sunday, downplaying confusion over the initial target date and who should actually get the additional jabs. President Joe Biden previously said boosters would be available to all this week. However, Fauci said it was always up to the FDA and its advisers to determine "exactly what that rollout would look like." On Friday, a key federal advisory committee recommended a third dose of the Pfizer-BioNTech COVID-19 vaccine six months after full vaccination for only people 65 and older and those at high risk of severe COVID-19. Dr. Francis Collins, director of the National Institutes of Health director, called the decision a preliminary step and predicts broader approval for most Americans “in the next few weeks.”

US closes part of Texas border, begins flying Haitians home

The U.S. on Sunday blocked the Mexican border at Del Rio, an isolated Texas town where thousands of Haitian refugees have crossed and set up a camp, hoping to stop the flow of migrants. About a dozen Texas Department of Public Safety vehicles lined up near the bridge and river where Haitians have been crossing from Ciudad Acuna, Mexico, into Del Rio, Texas, for almost three weeks. Many of the migrants have lived in Latin America for years, but they are now seeking asylum in the U.S. as economic opportunities in Brazil and elsewhere dry up.

The U.S. sent three flights of Haitians back to their homeland Sunday. Some said the recent devastating earthquake in Haiti and the assassination of President Jovenel Moïse make them afraid to return to a country that seems more unstable than when they left. The announcement marked a swift response to the sudden arrival of Haitians in Del Rio.
