Dimitrios Pagourtzis was seen entering the low-slung building at Santa Fe High School on Friday morning, armed and wearing a trench coat.
Like others who’ve terrorized American students, the 17-year-old planned to kill his peers and then himself, the authorities said. He opened fire, and the school erupted in chaos.
An alarm clanged, and in the art room, bloodied students cried for help. But once the bullets pierced his classmates’ bodies, the suspect surrendered, said Gov. Greg Abbott of Texas, and admitted “that he didn’t have the courage to commit the suicide.”
“Born to Kill” appeared on a T-shirt he posted on his Facebook page, along with images of the trench coat and an explanation of its decorations.
“Hammer and Sickle=Rebellion,” he wrote. “Rising Sun=Kamikaze Tactics. Iron Cross=Bravery. Baphomet=Evil.”
Mr. Abbott said that the gunman had used a shotgun and .38 revolver, both of which appeared to be obtained from the suspect’s father, who legally owned them.
The suspect also kept a journal, which detailed his plans for the attack and his suicide. Investigators, meanwhile, are scouring his journal, a computer and a cellphone that Mr. Abbott said showed the suspect had been planning the attack, and his own death.
Mr. Pagourtzis had no known confrontations with law enforcement, Mr. Abbott added. “As far as having a criminal history, he has none. His slate is pretty clean.”
He made the honor roll. He played defensive tackle on a school football team that was the pride of the town. His family was involved in the Greek Orthodox Church.
The day before the shooting, Mr. Ray and Mr. Pagourtzis went on a class field trip to Schlitterbahn, a water park in Galveston. On Friday, though, a different young man showed up at school in Santa Fe, wearing the coat and the “Born to Kill” T-shirt.
