The suspect in Friday's mass shooting that left 10 people dead at Santa Fe High School in southeast Texas has been identified by The Associated Press and other media outlets as 17-year-old student Dimitrios Pagourtzis.
Texas Gov. Greg Abbott confirmed the number of deaths in a news conference Friday afternoon. Nine of the dead were Pagourtzis' fellow students at the high school, and the tenth was a teacher. At least 10 others were injured in the shooting.
CBS first reported the identity of the shooting suspect. Pagourtzis has been charged with capital murder and two counts of assaulting a peace officer. He is being held without bond at the Galveston County Jail.
The shooting in a classroom in Santa Fe started just after 7:30 a.m. The first call to authorities came in at 7:32 a.m.
Multiple media reports indicate that Pagourtzis shouted "Surprise" before he began shooting in an art classroom. When the shooting was over, he reportedly told authorities he originally planned to take his own life after the shooting, but lost his nerve.
According to the Santa Fe Independent School District Police Department, a second person of interest, who has not been identified, was also detained Friday morning. Both are reportedly students at Santa Fe High School.
The Houston Chronicle reported that the assailant was armed with a .38 caliber pistol, a shotgun and pipe bombs. The guns reportedly belong to Pagourtzis' father.
One Santa Fe High School student, Dustin Severin, told KTRK he saw Pagourtzis wearing a trench coat and "big boots" to school, before he heard the initial three shots. Severin also told the station the shooter had been bullied in the past.
Screenshots of Pagourtzis’ now-deleted Facebook page show a picture of a T-shirt with “Born to Kill” written across it and a trench coat covered in insignia that included an iron cross, hammer and sickle and other images, KHOU reported.
Investigators also found explosive devices, including at least one Molotov cocktail, both inside the school and in the area surrounding the campus. Law enforcement officials believe Pagourtzis assembled the explosives himself.
Officials urged residents to exercise caution in the neighborhoods surrounding the school and to call police at 409-927-3310 if they find any suspicious items.
A family reunification center has been established at the Alamo Gym near the high school, located at 13306 Texas Highway 6.
"We hope the worst is over, and I really can't say any more about that because it would be pure speculation," Assistant Principal Cris Richardson said, according to The Associated Press.
Students interviewed by local media outlets say they heard loud gunshots, possibly from a shotgun, ring out from an art classroom during the first period of the school day.
Raul Reyes, a spokesman for University of Texas Medical Branch Hospital, told media that UTMB Galveston admitted three patients Friday after the shooting: a middle-aged male in critical condition with gunshot wounds to his chest, a middle-aged woman in good condition with a gunshot wound to her leg, and a younger female, also in good condition with a gunshot wound to her leg.
Dr. Safi Madain, ER director at Clear Lake Regional Medical Center in the neighboring town of Webster, told CNN that his team treated eight patients with gunshot wounds, six of whom were sent home from the hospital before 6:30 p.m. At that time, one victim at Clear Lake was in good condition, and the other remained in critical condition, Madain said.
According to the advocacy group Everytown for Gun Safety, there have been 311 school shootings across the U.S. since 2013.
The bloodshed roughly 30 miles southeast of Houston is the worst mass shooting in the U.S. since February, when 17 people were gunned down and 15 more were wounded at Marjory Stoneman Douglas High School in Parkland, Fla.
Students at Santa Fe High School joined other students across the country on April 20 in walking out of school to bring awareness to the issue of school shootings. Just 21 school days later, the very horror and tragedy they raised their voices against manifested itself in their classrooms and halls.
President Donald Trump weighed in on the Santa Fe shooting from the East Room of the White House.
"Unfortunately, I have to begin by expressing our sadness and heartbreak over the deadly shooting at Santa Fe High School in Texas," Trump said Friday. "This has been going on too long in our country. Too many years. Too many decades now."
Santa Fe is a city of about 13,000 residents. Santa Fe High School has an enrollment of about 1,400.
Local authorities as well as officials with the Bureau of Alcohol, Tobacco, Firearms and Explosives, FBI and Texas Department of Public Safety responded to the scene. As of 11:15 a.m., Santa Fe ISD police were taking the lead on the investigation.
