The teenager who allegedly used a shotgun and a revolver to kill 10 people and wound 10 others at a Texas high school Friday admitted he didn't shoot people he liked and meant to kill the ones he did target, a probable cause affidavit says.Suspect Dimitrios Pagourtzis, 17, has cooperated with police, said Galveston County Magistrate Mark Henry said. Henry denied bail for the student, who is accused of capital murder of multiple people and aggravated assault on a public servant.Students at Santa Fe High School, not far from Houston in southeastern Texas, scrambled for safety after they heard shots just after class began Friday morning. Nine students and one teacher were killed, a law enforcement official told CNN.Pagourtzis said little during a video court appearance, answering "Yes, sir" when asked whether he wanted a court-appointed attorney. He was not asked to enter a plea.The probable cause affidavit says he told an investigator he spared people he liked because he wanted his story told.The alleged shooter used a shotgun and a .38 revolver that were legally owned by his father, Gov. Greg Abbott told reporters. Two school resource officers were on the campus and confronted the shooter "early on in the process," Abbott said.Live updates on the school shootingLatest developments?

The officer was working as a Santa Fe officer, a police union official tweeted.What we know about the shootingEarly morning attackGunfire erupted at the school, about 20 miles outside Galveston, not long after classes began around 7:30 a.m. CT, officials said. Authorities later found explosive devices -- including pipe bombs and pressure cookers -- in and near the school, the law enforcement official said.The suspect is believed to be a student. A second person -- also believed to be a student -- has been detained as well, Harris County Sheriff Ed Gonzalez said earlier.The male that Gonzalez described as a suspect was injured, a law enforcement official said on condition of anonymity.Investigators believe that the second person, an 18-year-old, may be an accomplice but not a shooter, a law enforcement official said.Two law enforcement officers are among the injured, according to a law enforcement source.One man is in critical condition with a gunshot wound in one of his arms, said David Marshall, chief nursing officer for University of Texas Medical Branch hospital.This is the 22nd US school shooting since the beginning of the year, and the third instance in eight days in which a gunman was on a school campus.Witnesses described students running from the school as they heard gunshots; they also described hearing an alarm at the school, though the sequence of events wasn't immediately clear.Authorities found explosive devices in the high school and in adjacent areas, said Walter Braun, Santa Fe Independent School District police chief. It wasn't immediately clear if any had exploded.Because the devices were found, Braun urged people in the city of about 13,000 people to "not touch any items that look out of place, and call 911" if they see something suspicious.Investigators Friday afternoon were searching a trailer where they believe the devices were assembled, a law enforcement source said.The school has been cleared of all students and staff, who have been directed to a nearby facility to reunite with their families, Braun said.Witness: Shooter fired gun in an art classAn armed person walked into an art class at the school and began firing what looked like a shotgun, a witness told KTRK.The witness told KTRK she saw a girl shot in the leg.Victims were being treated at three hospitals, authorities said. Eight people went to Clear Lake Regional Medical in Webster, Texas; two patients were treated at Mainland Medical Center in Texas City; and four patients went to John Sealy University of Texas Medical Branch in Galveston. It is unclear whether they were all wounded.Six of the eight patients at Clear Lake Regional were discharged by Friday afternoon.Witnesses describe hearing an alarm as well as gunfireAngelica Martinez, a 14-year-old student, told CNN she and her schoolmates were being evacuated at one point "like it's a fire drill.""We were all standing (outside), but not even five minutes later, we started hearing gunshots," she said. "And then everybody starts running, but, like, the teachers are telling us to stay put, but we're all just running away.""I didn't see anybody shooting, but like (the gunshots) were kind of spaced," Angelica said, adding she heard about four shots.A witness who spoke to KTRK also said she heard an alarm. She didn't specify if that was before or after the gunfire she described in the art class.She said she couldn't describe the shooter."I didn't look. I just ran," she said.Another student, Dakota Shrader, told CNN affiliate KPRC that she heard gunshots only after hearing an alarm in the school."I was in the history hallway, and as soon as we heard the alarms, everybody just started leaving following the same procedure as ... (a) practice fire drill," Shrader said, breaking into tears. "And next thing you know, we just hear ... three gunshots, loud explosions, and all the teachers are telling us to run."MaKenna Evans, a 16-year-old sophomore, told CNN she was in geometry class when the shooting started.First, she heard a fire alarm, she said. When the students got outside, her principal told them all to run.Evans said students hid behind a building across the street from the school.The high school has about 1,400 students, according to GreatSchools.org.Trump: Mass shootings have been 'going on too long in our country'Trump addressed the school shooting, saying that mass shootings have been "going on too long.""Unfortunately, I have to begin by expressing our sadness and heartbreak over the deadly shooting at Santa Fe High School in Texas," Trump said from the East Room of the White House. "This has been going on too long in our country. Too many years. Too many decades now."Trump said federal authorities are coordinating with local officials."We grieve for the terrible loss of life and send our support to everyone affected by this absolutely horrific attack," Trump said.Trump has ordered US flags at federal facilities be flown at half-staff.The-CNN-Wire 7385

The world has spent the last several months wearing masks in public, avoiding gatherings and, in general, spending less time outside the home. But a new report suggests household transmission is one of the most common ways COVID-19 is spreading; an individual is most likely to contract COVID-19 from their spouse or significant other.That conclusion is part of a new report from the University of Florida which was published in the journal JAMA Network Open on Monday. Researchers looked at the results of 54 studies across 20 countries that included nearly 78,000 subjects.They found more than one in three, roughly 38%, of COVID-19 patients passed the virus to their spouses or significant others they live with."Infection risk was highest for spouses, followed by non-spouse family members and other relatives, which were all higher than other [close] contacts," the authors wrote.In the studies, about 17% of COVID-19 patients transmitted the virus to children they live with.Anyone living in the same home as someone who has contracted the coronavirus is at a heightened risk, but researchers say spouses and significant others are more likely to pass along the virus for various reasons, including "intimacy, sleeping in the same room, or longer or more direct exposure to index cases," according to the report's authors.The researchers found no significant difference between male and female transmission rates inside the home.A recent study from the Centers for Disease Control and Prevention found that 53% of people who live with someone who has COVID-19 will contract the virus within seven days.Health experts have urged those who have COVID-19 or have symptoms to wear a mask in their home, and isolate within the home as much as possible away from others under the same roof. 1798

The US Centers for Disease Control and Prevention continues to warn against eating any romaine lettuce harvested from the central Coastal growing regions of Northern and Central California amid a multistate outbreak of E. coli illnesses linked to romaine lettuce. The agency also reported Thursday that nine additional people have been reported ill since November 26.Now, 52 people have been infected with E. coli in this outbreak, which was announced in October, according to the CDC.Illnesses have been reported in 15 states: California, Connecticut, Florida, Illinois, Louisiana, Massachusetts, Maryland, Michigan, New Hampshire, New Jersey, New York, Ohio, Pennsylvania, Rhode Island and Wisconsin.Nineteen people have been hospitalized, including two who developed hemolytic uremic syndrome, a type of kidney failure. No deaths have been reported.Last month, the CDC and the US Food and Drug Administration updated their warning against eating or selling romaine lettuce products harvested in the California counties of Monterey, San Benito, San Luis Obispo, Santa Barbara, Santa Cruz and Ventura. 1110

The Wake Forest Institute for Regenerative Medicine says it has a new use for its bioprinting system. In the past they've 3D printed normal-size organs and tissues in hopes of someday implanting them in patients.For the coronavirus, the lab is creating organs using human cells that can be as small as a pinhead. They're focusing on the organs most likely to be infected by the disease. like the lungs.“And so we've been playing with a number of agents to, on both prongs what can make it more infective, what can make it less infective to try to sort this out for the future,” Anthony Atala, director for the institute said.Atala says he hopes the system will help in testing drugs before they hit the market.Drug companies do extensive testing and clinical trials in people before releasing a new medication.Atala says sometimes those companies find no serious side effects, but then years later, discover that it's toxic to patients taking it. Atala says testing a drug using the bioprinting system can tell if a drug is toxic in weeks instead of after years on the market.“Even though we've used the tool extensively for toxicity testing, it's also a tool that can be used for screening,” Atala said. “So we can test agents that are currently being considered for testing against COVID and test the efficacy of the treatment on miniature human organs made up of normal cells”To be clear, Atala said drug tests on 3D printer organs are not meant to replace clinical trials in humans, be are an added step to better predict what will happen in those trials. 1567

The U.S. has now recorded at least 100,000 cases of COVID-19 each day for the last three weeks.On Monday, at least 169,190 new cases of the coronavirus were recorded throughout the U.S., marking 21 consecutive days that the country has seen at least 100,000 new COVID-19 cases.During that time span — dating back to Nov. 2 — the number of people in the country hospitalized with complications from the virus has nearly doubled from 48,557 to 85,836. Currently, about 69% of those hospitalizations are occurring in the South and Midwest, meaning some hospitals in those areas — particularly rural hospitals — are currently operating at capacity.The massive spike in cases has also caused the number of deaths linked to COVID-19 on a rolling 7-day average to nearly doubled from 826 a day to 1,515 a day. The last time the U.S. saw as many deaths per day as it sees now came back in mid-May when the country was still recovering from the virus' silent and uncontained spread in early spring. Over the weekend, the U.S. surpassed 3 million new cases in November alone. The country has recorded 12.4 million cases of COVID-19 since the pandemic began, meaning about one-quarter of all of those cases have occurred this month alone.Despite the bleak outlook on the state of the pandemic in the country, Dr. Anthony Fauci, the county's top expert on infectious diseases, warned Monday that the pandemic could worsen further. He said that if Americans don't follow common-sense public safety measures on Thanksgiving, cases could spike even further in December."The chances are that you will see a surge superimposed on a surge," Fauci said.Fauci recommends limiting Thanksgiving gatherings to members of a single household. He also says Americans need to continue to follow five common public safety measures in order to limit the spread: Adopt uniform mask-wearing, keep social distance, avoid large crowds, gather outdoors as opposed to indoors and continuously wash hands. 1983
