Here's What We Know About Dimitrios Pagourtzis, The Suspected Santa Fe High School Shooter

Dimitrios Pagourtzis is suspected of killing at least eight people at Santa Fe High School in Texas.

Dimitrios Pagourtzis, 17, was identified as the shooter suspected of killing at least 10 people at Santa Fe High School on Friday.

Pagourtzis is being held on a capital murder charge with no bond, the Galveston County Sheriff's Office said. He might face additional charges, authorities said. The suspect has been booked into the Galveston County Jail.

The suspect had information contained in journals on his computer and cell phones that indicated that he "wanted to commit the shooting" and also wanted to kill himself after, Texas Gov. Greg Abbott said Friday.

The shooter gave himself up because he didn't have the "courage" to kill himself after the shooting, Abbott said.

Abbott did not identify the suspect.

He used a .38 revolver and a shotgun, Abbott said. But he did not own or legally possess either of these weapons — the suspect's father did. Authorities did not know if the father was aware that his son had taken the weapons from him.

Authorities detected various explosive devices, including a CO2 device and a Molotov cocktail, that belonged to the shooter. The explosives were found at a home and a vehicle, Abbott said. Authorities are cautious in searching two residences believed to be associated with the suspect because of the potential of finding explosive devices inside.

"One of the frustrating things in the early status of this case, unlike Parkland and Sutherland Springs, there were not those type of warning signs. We have what are often categorized as red flag warnings," Abbott said.

"Here the red flags warnings were either nonexistent or imperceptible. There is on his Facebook page a t-shirt that says 'Born to kill.' But as far as investigations by law enforcement agencies, as far as arrests or confrontation with law enforcement, as far as having a criminal history, he has none. His slate is pretty clean."

A man who answered a phone at a number associated with the family's residence declined to comment to BuzzFeed News.

A Facebook page that appeared to belong to Pagourtzis showed a photo of a custom t-shirt with the words "Born To Kill" on it. The photo was uploaded on April 30.

On the now-deleted Facebook page, Pagourtzis had also uploaded photos of a military green trench coat with what appeared to be Nazi-related insignia and a reference to "kamikaze tactics."

Facebook confirmed that they had removed the suspected shooter's profile.

"In line with our policy against mass murderers, we removed the shooter’s profile," the spokesperson told BuzzFeed News.

In another Facebook photo, the suspect appeared to be wearing a bisexual pride pin on his hat.

Students who knew Pagourtzis described him as a quiet teen who kept to himself and who appeared to "believe in evil."

The Instagram account followed several gun-enthusiast pages as well as President Trump and his family.

Here's another shot from what appeared to be his Instagram:

 16-year-old sophomore at Santa Fe High, told BuzzFeed News that her cousin was in the room when Pagourtzis allegedly began shooting.

Pagourtzis was quiet and kept to himself, Bailey said. He often wore a trench coat, she said, and someone had once told her he “believed in evil.”

Avery Garza, another sophomore at the school, said a friend of his was in the room when Pagourtzis allegedly opened fire.

Garza, who was in a football class with Pagourtzis, told BuzzFeed News, that Pagourtzis was “always quiet.”

Pagourtzis was a defensive tackle for the Santa Fe JV Indian football team, according to a 2016 report.

“We would have never thought it was him,” he said. “I’ve never talked to him. He never talked to anyone.”

Garza said Pagourtzis hadn’t been at school for several days prior to the shooting.

Another student, identified only as Dustin, told ABC 13 that the shooter was wearing a trench coat and big boots.

“I used to talk to the shooter himself and he used to not seem like he would do that,” Dustin said. He added that Pagourtzis would "snap" and that “the coaches would bully him and call him names – he just didn’t have a lot of friends.”

“I believe one of the victims that he shot bullied him," Dustin said.

An Instagram account that appeared to belong to the suspect, contained a photo of weapons with the caption "Hi fuckers."

The Instagram account followed several gun-enthusiast pages as well as President Trump and his family.
