Katie Holt's decision to have a gunshot wound kit in her classroom wasn't just a sobering reminder of America's mass shooting reality. On Thursday, it likely saved a life.

Holt, a choir teacher Saugus High School in Santa Clarita, California, used that kit to wrap the wounds of a student who ran into her room after she'd been shot. The student survived — but in this case, that single kit was barely enough, NBC News reports.

Two students were killed and three more were hurt when a 16-year-old fellow student opened fire over a 16-second period as school began Thursday morning. Those injured included the freshman girl Holt treated, who was among 30 to 40 who rushed into Holt's room. "The rookie teacher, who started in January, quickly wheeled a grand piano in front of the door and ushered dozens of her students into an office, locking the door behind them," The New York Times writes.

But after confirming the girl had been shot twice, Holt left the office and got her gunshot wound kit — she "only had one," she said. Holt wrapped the girl's wounds on her shoulder and torso while a "really brave freshman" helped apply pressure, she tells NBC News. And all around her, students were muffling their crying while one called the police and another "grabbed a fire extinguisher — just in case the gunman made it inside," the Times continued.

The alleged shooter was found after more than an hourlong search in the surrounding neighborhood and as schools in the district were locked down. The suspect was taken to a hospital for treatment of presumably self-inflicted gunshot wounds in the head and is still alive. Kathryn Krawczyk

Japan is warning fans not to get their hopes up too high about watching the Olympics next year, NBC News reports. Speaking Friday, Tokyo organizing committee CEO Toshiro Muto said, "I don't think anyone would be able to say if it is going to be possible to get [the pandemic] under control by next July or not" — suggesting that yes, there's once again a big question mark about if the summer Olympics are even going to happen.

The 2020 Olympics were already pushed back to 2021 last month over concerns about the coronavirus outbreak. Muto, though, downplayed guarantees of the rescheduled 2021 Games, saying "we're certainly not in a position to give you a clear answer."

When asked about if there was a plan B for the Olympics, Muto stressed that the athletic competition shouldn't be on the forefront of anyone's minds right now. "Rather than think about alternatives plans, we should put in all of our effort," he said. "Mankind should bring together all of its technology and wisdom to work hard so they can development treatments, medicines, and vaccines." Jeva Lange

Thousands of people normally attend the pope's Holy Week celebrations at the Vatican, but needless to say things are going to be a little different in the Eternal City this year. For what is believed to be the first time in modern history, "all the Liturgical Celebrations of Holy Week will take place without the physical presence of the faithful" due to the coronavirus outbreak, the Vatican writes.

Pope Francis will still head two masses on Friday: The Vatican Liturgy of the Lord's Passion at 12 p.m. ET, and the Stations of the Cross, or Via Crucis, at 3 p.m. ET, which will be held in front of Saint Peter's Basilica rather than at the Colosseum, as is traditional.

There are several options for watching virtually. The simplest is to tune into the Vatican's ongoing live stream at the corresponding time, below. The Vatican's full Holy Week streaming schedule, which is listed in Rome's time zone, can be viewed here.

CatholicTV will also stream the Celebration of the Lord's Passion with Pope Francis at 12 p.m. ET, and rebroadcast it at 5 p.m. ET. The Stations of the Cross will be broadcast at 8 p.m. ET. You can watch their broadcasts here, and access the CatholicTV schedule here. Another option is to view the events through Aleteia; you can access the Celebration of the Passion here and the Stations of the Cross here, along with more information about this year's liturgies.

Forbes also notes that the Holy Week events will be "archived for later viewing," in case you miss them. You can browse the Vatican's YouTube videos here. Jeva Lange

The economic toll of the COVID-19 coronavirus pandemic is severe and growing, and "no one wants to reopen America more than Donald Trump," Vice President Mike Pence said Thursday, albeit "responsibly." The U.S. is at "the top of the hill," Trump said at Thursday's White House briefing. "Hopefully, we're going to be opening up — you could call it opening — very, very, very, very soon, I hope."

Trump can't actually restart the economy since he did not shut it down — most states have issued stay-at-home orders to halt the spread of the disease, and only states can lift them. Nevertheless, the president has privately "sought a strategy for resuming business activity by May 1," The Washington Post reports, and "in phone calls with outside advisers, Trump has even floated trying to reopen much of the country before the end of this month."

Trump's top advisers are more conservative, to varying degrees, The Wall Street Journal notes. Treasury Secretary Steven Mnuchin told CNBC Thursday he thinks the U.S. economy may be ready to reopen by the end of May, while Federal Reserve Chairman Jerome Powell said "most people expect" employees to be able to safely return to work "after the second quarter, which of course ends on June 30." Dr. Anthony Fauci told CBS News he could see public gatherings resuming this summer "if we do the things that we need to do to prevent the resurgence" of the coronavirus.

"Health experts say that ending the shutdown prematurely would be disastrous," the Post reports, creating another spike in infections and forcing another shutdown "because U.S. leaders have not built up the capacity for alternatives to stay-at-home orders — such as the mass testing, large-scale contact tracing, and targeted quarantines." Pence said Thursday the U.S. has tested two million people, or less than 1 percent of the U.S. population, and Trump rejected the idea that mass testing is necessary to restart the economy.

An early opening is "an aspirational goal," Sen. Lindsey Graham (R-S.C.), a Trump ally, told the Post. "It has to be a science-based assessment, and I don't see a mass reopening of the economy coming anytime soon." Peter Weber

John Prine, who died this week from complications of COVID-19, left the world a catalog of great songs and a legion of fans who revere them. His death during an unprecedented time of mass self-quarantine also shaped the tributes — a singer and an instrument. Among Prine's ardent admirers is Stephen Colbert. He asked Brandi Carlile to sing one of Prine's songs on Wednesday's Late Show, and Dave Matthews continued the tribute on Thursday. Watch him perform Prine's elegiac "Speed of the Sound of Loneliness," alone at his house, below. Peter Weber

To limit the spread of the COVID-19 coronavirus, the Centers for Disease Control and Prevention (CDC) started advising last week that Americans wear face masks in public in areas where they can't keep a safe six-foot distance from people. But U.S. health officials don't want people buying masks — the limited supply is needed in hospitals dealing with the pandemic.

Not everyone knows how to make a mask at home, though, and in a CNN town hall Thursday night, Dr. Sanjay Gupta demonstrated some options, including creating a mask from a bandana and large hair bands. Dr. Celine Gounder fielded a question on how to safely use and sanitize your homemade cloth mask: remove the mask from behind your ears, then throw it in the washing machine and wash your hands.

Surgeon General Jerome Adams also demonstrated how to make a mask using two rubber bands and a cut-up T-shirt, though a bandana, hand towel, tea towel, or old scarf would also work.

Researchers suggest using tighter-knit fabrics — hold it up to the light to get a sense of the density of the weave — but say any fabric is better than none. You don't need to wear the mask when you go for a walk outside by yourself, Gupta said, but when you can't social distance, the mask can help prevent you from spreading the virus to others, just as their masks protect you. "Everyone has to behave like they have the virus," he said. Peter Weber

The Health and Human Services Department announced Thursday evening that it will no longer end support for community-based COVID-19 testing sites on Friday, as originally planned. "The federal government is not abandoning any of the community-based test sites," Adm. Brett Giroir, assistant secretary for health, told reporters over the phone. "I want that to be loud and clear." Instead, the local authorities hosting the testing sites can decide whether to shift to running the program themselves, as HHS had envisioned, or continue getting federal assistance.

After a late, botched start, U.S. labs are processing thousands of coronavirus tests a day, the Centers for Disease Control and Prevention reports. But "testing availability remains a signature failure of the battle against the coronavirus in the United States," and "as the virus has spread from state to state infecting hundreds of thousands of Americans, demand for testing has overwhelmed many labs and testing sites," The New York Times reports. "Doctors and officials around the country say lengthy delays in getting results have persisted and that continued uneven access to tests has prolonged rationing and hampered patient care." CNN looked at what went wrong in a Thursday night report.

Giroir said the 41 community testing sites around the country had proved a success, testing more than 77,000 people, mostly health-care workers and first responders, NPR reports. And given the enduring testing setbacks, the HHS decision to stop sending testing materials, protective equipment, and other support to the sites had surprised some people, including members of Congress. "I'm extremely relieved that HHS has reversed its decision," Rep. Madeleine Dean (D-Pa.) told NPR. Peter Weber
