Law enforcement sources have reportedly identified the suspect in Friday morning’s deadly shooting at Santa Fe High School is Dimitrios Pagourtzis, a 17-year-old student who attends the high school.

Sources told CBS News that Pagourtzis is the Texas student that’s in custody. The identity of another male student being detained and questioned isn’t immediately known.

A student who claimed to have been next door to the shooting told CBS News that he saw a student with a “black trench coat,” sawed-off shotgun, pistol grip, and “something sharp” emerge from the classroom. He said the student went back into an art room. A teacher pulled the fire alarm as the students had no phone service, the student said.

As CrimeOnline previously reported, Santa Fe Independent School District (SFISD) Police Chief Walter Braun revealed Friday afternoon that they believe “fewer than” 10 people died and six were injured in the high school shooting. He went on to confirm that explosives were spotted at the high school and in surrounding areas.

Law enforcement sources told KHOU that several agencies are searching a mobile home where Pagourtzis is believed to have lived.

According to the news station, the 17-year-old recently posted a photo of himself wearing a shirt saying “Born to Kill.” Another social media post reportedly displayed a long coat with a Nazi cross.
