 SANTA FE, Texas — A shotgun-toting teenager opened fire at a Texas high school Friday, killing at least 10 people and leaving a cache of explosives in and around the area. 
 
 Nine students and one adult were killed at Santa Fe High School in Santa Fe, Texas, amid gunfire that erupted before classes began, a law enforcement official not authorized to comment publicly told USA TODAY. The suspect was later taken into custody. 
 
 Ten other people were wounded, Texas Gov. Greg Abbott said during an afternoon news conference. 
 
 “We come together today as we deal with one of the most heinous attacks that we’ve ever seen in the history of Texas schools," Abbott said. "It’s impossible to describe the magnitude of the evil of someone who would attack innocent children in a school." 
 
 The attack once again heated up opinions about gun control laws and how to stop America's gun violence. 
 
 The shooting was the worst since Feb. 14, when a former student killed 17 people at a Florida high school and caused polarized debate about gun control. 
 
 The official said multiple pipe-bomb-type explosives were recovered at the school, but investigators were still going through the building. Authorities also found other explosives, including a CO2 device and a Molotov cocktail, Abbott said. 
 
 Dimitrios Pagourtzis, 17, was arrested after the shooting and charged with capital murder and aggravated assault of a peace officer. 
 
 After being read his rights, he admitted to the shootings and told officers he targeted students he didn't like, according to a court filing. 
 
 "He did not shoot students he did like so he could have his story told," an officer wrote in a probable cause affidavit filed in Galveston County court. 
 
 He made his first appearance in court Friday evening, hanging his head and looking down as a judge asked him routine questions, such as whether he wanted a court-appointed attorney. 
 
 "Yes, sir," he mumbled as he fiddled with his hands. 
 
 Pagourtzis kept a journal on his computer and a cell phone that detailed the plans for his attack, Abbott said, adding Pagourtzis also hoped to take his own life after the shooting but instead gave himself up to law enforcement. 
 
 It’s not USA TODAY’s policy to identify minors charged with crimes. Due to the magnitude of the event and the fact the suspect could be charged as an adult, USA TODAY has decided to identify the suspect. 
 
 Pagourtzis was armed with a shotgun and a .38-caliber pistol, Abbott said. The guns were owned by the boy's father, Abbott said. 
 
 Investigators were working on search warrants for two residences and a car, but were hampered by concerns about the potential for more explosives, Abbott said. 
 
 “They want to make sure they can enter them without anybody being harmed," Abbott said. 
 
 The school had two police officers on duty, and one was critically wounded in the shoot-out, according to Steven McGraw, director of the state Department of Public Safety. A state trooper also engaged the gunman, McGraw said. 
 
 “We know that because they were willing to run into that a building and engage them right now, other lives were saved," McGraw said. 
 
 At least one other person was in custody, but the official believed the person was not believed to be a suspect. 
 
 After explosives were found at the school and off campus, police and the Santa Fe Independent School District urged people to report any suspicious items found around town. 
 
 First responders received the first calls about a gunman opening fire in a classroom at 7:32 a.m. Witnesses fleeing the school described chaos as they jumped over fences and ran to nearby businesses. 
 
 "I was shaking, my anxiety was bad," Megan Hunter said after fleeing her classroom. "I don’t even know what to think." 
 
 The fire alarm went off during the attack, adding a level of confusion for those at the school and for first responders. 
 
 It's unclear whether a student, teacher or the gunman pulled it. Some students told reporters that students pulled the alarm after seeing the gunman, and one said a former Marine who is a teacher at the school pulled the alarm. 
 
 But Tyler Turner, a student at the school, told Fox News that the gunman pulled the alarm. Turner said a few of his friends walked past the gunman, who looked suspicious. 
 
 "He pulled the fire alarm so we all went outside, and then we heard 3 shots," Turner said. 
 
 The suspect in the Florida high school shooting in February also was accused of pulling the fire alarm, allowing him to mow down students fleeing the school. 
 
 For some students inside the school, the fire alarm made them think the emergency wasn't as dire. Branden Auzston, an 11th grader at the school, heard the alarm and thought it may have been a fire since they had a drill two weeks ago. 
 
 “We go outside and we were told to get in the grass,” Auzston said. “Then I see my teacher and she screamed ‘Just run!’” 
 
 He said it felt like a movie and nothing seemed real. 
 
 Eight hours after shots were fired inside his high school, Auzston and his girlfriend, Daisy Sullivan, gathered at the H-E-B parking lot across from what is being referred as the Alamo Gym, where parents and guardians are being reunited with students. 
 
 They hoped to find Auzston's best friend, Chris Stone. He said no one has talked to him since this morning. 
 
 "I fell asleep earlier because I didn’t feel good, and I thought I would wake up and it would be over and everything would be normal — but it’s not," Sullivan said, adding in two weeks she's scheduled to graduate. 
 
 Leila Butler, another student, told CNN she didn’t hear gunshots, but just the fire drill that prompted the evacuation. 
 
 “We’re all really just devastated that such a tragedy could happen in our small town,” she said. Coupled with Hurricane Harvey at the start of the school year, “it’s more than we can handle,” she said. 
 
 TV aerial footage showed groups of students being herded out of the rear of the school and a sheet believed to be covering a body on the lawn outside. Yellow buses stood at the ready to shuttle students away. 
 
 President Trump called it a "very sad day" at the White House. He spoke with Abbott and pledged to work with the governor to provide appropriate federal assistance. 
 
 "My administration is determined to do everything in our power to protect our students, secure our schools and to keep weapons out of the hands of those who pose a threat to themselves and to others," Trump said. "May God heal the injured and may God comfort the wounded."

 The president ordered flags be flown at half-staff. 
 
 Later Friday evening, hundreds of locals crowded into a grassy lot next to Texas First Bank for a vigil honoring the slain and injured. 
 
 Some cried and hugged, others held roses or white candles. Many were students who, just hours earlier, had hid under desks or flung themselves over fences to flee the gunman. 
 
 A table held 10 candles, 10 white roses and 10 bibles for the 10 victims. 
 
 “Words cannot express the sorrow of our hearts for those we have lost,” said Leigh Wall, superintendent of Santa Fe ISD.

 SANTA FE, Texas (AP) — The Latest on a shooting at a high school in Santa Fe, Texas (all times local): 
 
 1:05 p.m. 
 
 A law enforcement official has identified a person in custody in the Houston-area school shooting as 17-year-old Dimitrios Pagourtzis. 
 
 The official was not authorized to discuss the shooting by name and spoke on condition of anonymity to The Associated Press. 
 
 Authorities say eight to 10 people, mostly students, were killed in the nation's deadliest such attack since the massacre in Florida that gave rise to a campaign by teens for gun control. 
 
 A woman who answered the phone at a number associated with the Pagourtzis family declined to speak with the AP. 
 
 She said: "Give us our time right now, thank you." 
 
 Pagourtzis plays on the Santa Fe High School junior varsity football team, and is a member of a dance squad with a local Greek Orthodox church.

 SANTA FE – Seventeen-year-old Trey Lemley was one week past prom, two weeks from the end of his junior year. 
 
 He was surrounded by safe, familiar things. The long tables of the Santa Fe High School art lab. 
 
 The walls covered in murals and paintings. The friends who had made them. 
 
 Then, one of his classmates, clad in a trenchcoat, entered the room with a shotgun and a revolver. 
 
 Trey dropped his phone, flung himself inside a closet and barricaded the door, according to his sister, Courtney Lemley. 
 
 When Trey came out, three bodies lay on the floor in pools of blood. 
 
 When Trey came out, the old, safe Santa Fe High School was gone. 
 
 Now Playing: 
 
 When Trey came out, he and his district of more than 4,000 students, about 30 miles south of Houston, had joined a growing cadre of U.S. communities with children who will never come home, racked by a mass shooting and represented by political leaders who have no clear consensus on how to stop them. 
 
 About 7:30 a.m. Friday, 17-year-old Dimitrios Pagourtzis killed 10 and injured at least 10 more before a Santa Fe school police officer and a Texas state trooper intercepted him. He eventually emerged from the art class and surrendered, according to an arrest affidavit.

 The school officer, 49-year-old John Barnes, suffered a gunshot to the upper arm, critically wounding him with severe blood loss. The dead included students and an educator. 
 
 Police also detained two people of interest in the case, Gov. Greg Abbott said at a news briefing Friday at the school. One was at the scene and had "suspicious reactions" after the shootings, and officials were unsure whether that person was involved in the attack, Abbott said. The other was being interviewed. Abbott gave no other details about them. 
 
 Pagourtzis claimed to have acted alone and was cooperating with authorities, said Galveston County Judge Mark Henry, the county's top elected official. 
 
 Authorities said Pagourtzis deployed inoperable explosive devices, perhaps to stoke fear. They were checking for more devices in Pagourtzis' vehicle and home, about three miles northwest of the school, Abbott said. 
 
 The dead include students Angelique Ramirez, 15, and Jared Black; and Cynthia Tisdale, a teacher's aide in the art class, according to their family members. 
 
 Among the injured were Rome Shubert, 16, a member of the school's baseball team who was treated and released after being grazed on the back of the head; student Clayton Horn, shot in the arm and leg; and sophomore Trenton Beazley, one of Shubert's baseball teammates, who was struck in the back by bullet fragments. 
 
 It was the worst mass shooting in America since Valentine's Day, when 17 people died at a high school in Parkland, Florida, and perhaps the worst school shooting in Texas since Charles Whitman killed 17 in a rampage from his perch in a University of Texas tower in 1966. There have been 16 school shootings nationwide in 2018, according to a database maintained by the Washington Post. 
 
 The shooting set off another enactment of the nation's familiar scenes of school terror: Students watching classmates die. Fleeing, their belongings searched by armed officers. Parents, tortured by lack of information, flocking to the school and hospitals. Desperate pleas for word of the missing on social media. 
 
 Blake Wingate, 16, and Kane Hopkins, 15, were getting ready to leave their first-period class near one of the school's three gyms when they heard fire alarms blare. They moved toward a hallway. 
 
 Three gunshots. Inches away, a window shattered. A teacher screamed for students to run. 
 
 The teens tried to run back to the gym. The door was locked. Other students joined as they tried to muscle open doors to the second gym. 
 
 Those were locked, too. 
 
 They found one unlocked door leading to the third gym and ran across a basketball court and outside to the school's parking lot. 
 
 Wingate saw a classmate begging for help, holding a teenager, the body limp. He and Kane kept running, intent on escape. 
 
 Eight people crammed into Wingate's two-door Jeep as more students streamed out of the school and across Highway 6. 
 
 Wingate drove to Hopkins' house. As they arrived, one friend threw up. 
 
 They spent the rest of the day watching news and texting friends in a desperate attempt to learn their classmates' fates. 
 
 They still don't know what happened to a friend whose parents tried and failed to find him at local hospitals. 
 
 They don't want to go back to school. It doesn't feel safe. 
 
 "It keeps replaying in my head," Wingate said. "It's a weird story that will stay in my head for the rest of my life. Just how close I was." 
 
 Other students jumped fences and fled to nearby woods or took shelter behind a mechanic's shop across the freeway. 
 
 Avari Creekmore, 16, got to school a little late. She heard fire alarms. She saw blood on a hallway floor and heard shooting. 
 
 "I took off running. I turned and saw him with whatever he had and I ran," she said, referring to the shooter. "I called my mom and said 'We have an active shooter at school,' and she said, 'I'm on my way.'" 
 
 The odor of gunpowder hung in the air. 
 
 "I just thought to run away from it," Avari said. "I just thought if he was near me just, God, get out of his sight." 
 
 Suzannah Salazar, 17, said she heard what sounded like four pops in the nearby art classroom, then she ran. 
 
 Hours after the shooting, she was still waiting to hear what had happened to her 16-year-old sister, Sarah, who she believes was in the room. 
 
 "I'm just hoping my sister comes back," she said. "I'm trying to stay as calm as I can." 
 
 Freshman Kali Reeves, 15, ran to a convenience store on the highway. 
 
 "All I know is, several are dead, a friend of mine was shot," Reeves said. "I know one girl is dead; she took a shot to the head." 
 
 Parents rushed to a complex of school district buildings about three miles from the high school, at a landmark known as the Alamo Gym. Some met relief as they found their children there. Others met only frustration. 
 
 "You shouldn't have to be waiting three hours to hear where your kid is," said Lesley Tribble, a 29-year-old who said she is the legal guardian of student Angelique Ramirez. 
 
 "She's easily identifiable — she has fire-red hair and two lip piercings," Carli Daffern, 14, said of Ramirez, who she said is her best friend and neighbor. 
 
 "None of us can get any real intel," Tribble wrote in a text message. "We've been calling hospitals asking because we still can't get any names or anything ... (Authorities are) trying to keep people calm but names aren't being released and now certain parents are getting riled up." 
 
 Leia Olinde, a local business owner, came to look for her aunt, Tisdale, but acknowledged she was growing more concerned. 
 
 "If everything was fine and she was OK she would have found a way to contact her husband by now," she said. 
 
 Community members and officers escorted families out of the facility by early Friday evening. Some walked briskly, heads down. Others, sobbing, needed guidance, a supportive hand on an arm. One woman pulled her T-shirt up to cover her face. 
 
 Officers blocked traffic. Friends or family had cars waiting. The community had seemed to reach a silent agreement that, at the very least, they could help the families leave this place, saturated with 10 solid hours of stress and uncertainty, quickly. 
 
 Tribble stayed. Just before 6 p.m., she learned Ramirez died. 
 
 Pagourtzis appeared in the evening before Henry, the county judge, who arraigned him on charges of capital murder and aggravated assault on a public servant. Henry denied bond. Pagourtzis made a quick appearance and stayed mostly silent. He asked for a court-appointed lawyer. 
 
 Investigators found carbon dioxide canisters wrapped with duct tape but no detonators, and a pressure cooker with an alarm clock and nails, but no explosive, Henry said. They also discovered an unspent Molotov cocktail — a bottle filled with flammable liquid. 
 
 "I think he wanted people to think they were explosives, but they were not," Henry said, adding authorities have no reports of explosions during the shooting. 
 
 Still, investigators took their time searching Pagourtzis' vehicle and house, several miles from the high school on Highway 6. 
 
 Pagourtzis used guns owned by his father, Abbott said, and did not have a legal right to possess them. 
 
 "I have no information ... whether the father knows the weapons were taken," he said. 
 
 No clear motive emerged, but Abbott said the teen revealed in journals that he had planned to kill himself after the attack. 
 
 "He didn't have the courage to end his life," Abbott said. 
 
 The student's social media persona included a photo of a "BORN TO KILL" T-shirt, German nationalist symbols and indications of an affinity for guns. 
 
 He also participated in a Greek Orthodox dance team, according to a church website. 
 
 Hopkins and Wingate, who fled the school in the Jeep, said they knew Pagourtzis from the football team and welding classes. 
 
 "He always wore dark clothes and that trench coat," Wingate said. "He would go outside and sit in a corner. The teacher always had to go out to find him." 
 
 A woman who answered the phone at a number associated with the Pagourtzis family declined to speak with The Associated Press. 
 
 "Give us our time right now, thank you," she said. 
 
 In the arrest affidavit, officers said Pagourtzis told them he avoided shooting students he liked, "so he could have his story told." 
 
 REACTION: 'Yall been sending thoughts and prayers for two decades now' 
 
 The high school's Earl Routh Field House turned into a command post for law enforcement. They established a mass casualty unit, and a makeshift morgue. Bodies remained inside the school into the evening. 
 
 Gulf Coast Regional Blood Center put out a call for donations, especially for type O negative. 
 
 Leaders across the political spectrum condemned the violence. Abbott, a Republican, said he planned to convene a roundtable on school shootings to hear from victims as well as proponents of gun rights. 
 
 Lt. Gov. Dan Patrick, a Republican from Houston, said a response should be focused on access to schools and retrofitting schools to prevent attacks. He said gun owners should lock them up to keep them safe. 
 
 Democratic State Rep. Gene Wu of Houston, however, tweeted: "Y'all been sending thoughts and prayers for two freaking decades now. Time to try something new." 
 
 President Donald J. Trump in February promised to stand up to the National Rifle Association to impose new gun restrictions, before telling the NRA in May that the Second Amendment would "never ever be under siege as long as I am your president." 
 
 On Friday, Trump emphasized keeping guns away from people who shouldn't have them. 
 
 "This has been going on too long in our country. Too many years. Too many decades now," he said. "We grieve for the terrible loss of life and send our support and love to everyone affected by this absolutely horrific attack. To the students, families, teachers and personnel at Santa Fe High, we're with you in this tragic hour and we will be with you forever. My administration is determined to do everything in our power to protect our students, secure our schools and keep weapons out of the hands of those who pose a threat to themselves and to others." 
 
 Former Astronaut Mark Kelly, who lived in the area of Santa Fe, near Johnson Space Center, for 15 years, said he and his wife, former Congresswoman Gabrielle Giffords were devastated. Giffords was injured in a shooting at an event in her Arizona district in 2011. 
 
 "It is our moral obligation to protect the vulnerable," Kelly wrote on social media. "The adults, the politicians, are responsible for the safety of children." 
 
 Santa Fe had an active shooter drill in February, junior Brittany Hale said. It then went on lockdown Feb. 28, 14 days after Parkland, after a threat was reported, junior Jacob Smirkik said. Though school was in session the next day, he said few attended. 
 
 "This time," he said, "there was no warning." 
 
 On Thursday, David Hogg, a Parkland student, had a chilling premonition as he spoke to reporters at an event in Los Angeles. 
 
 "There is someone alive right now that will not be alive at this time tomorrow and has never even thought about gun violence," he said, "but everyone around them will have to for the rest of their lives." 
 
 Minutes after the Santa Fe shooting, it was becoming clear that the schools would forever be linked. 
 
 "Santa Fe High, you didn't deserve this," tweeted Emma González, an outspoken Parkland survivor. "You deserve peace all your lives, not just after a tombstone saying that is put over you. You deserve more than Thoughts and Prayers, and after supporting us by walking out, we will be there to support you by raising up your voices." 
 
 Santa Fe students walked out just last month in support of the national protests against gun violence in schools. 
 
 In one photo that surfaced again Friday, a group of those walking out held up a poster. 
 
 Someone had scrawled on it in black marker: "Santa Fe High School says #NeverAgain."

– Ten people are dead and 10 more wounded after Friday morning's shooting at a high school in Santa Fe, Texas, says Gov. Greg Abbott. No IDs have been released, but earlier Harris County Sheriff Ed Gonzalez said most victims were students at Santa Fe High School. USA Today reports that nine of the dead are students. The suspected gunman, a student at the school, is in custody, and Abbott said "one or two" other people of interest were being interviewed, but it was unclear what, if any, role they might have played in the attack. Identified: The alleged shooter has been identified as 17-year-old Dimitrios Pagourtzis, a junior at the school. The AP says he played on the school's JV football team and belongs to the dance squad of a local Greek Orthodox Church. KHOU reports that he recently posted an image of a T-shirt reading "Born to Kill" and a caption of "we all die sometime." He also reportedly posted images of knives, guns, and a coat with Nazi insignia. Abbott said Pagourtzis told police he planned to commit suicide but couldn't go through with it. Explosives: Police say possible explosives were found at the school as well as at a site off campus. "Evidently this guy threw pipe bombs," one law enforcement official tells the Houston Chronicle. "We don't know if any of them went off." Bomb technicians also were at a home in Galveston County, a few miles from the school, reports KTRK. Weapons: Pagourtzis used two guns in the attack that he stole from his father, a shotgun and a .38 revolver, said Abbott, per the Washington Post.
