A student is in custody after a shooting at a Texas high school left 10 dead and another 10 injured.
The 17-year-old student, identified as Dimitrios Pagourtzis by law enforcement, was arrested at the scene of the shooting at Santa Fe High School on Friday morning.
Galveston County Sheriff Henry Trochesset said he is being held on capital murder charges without bond at the Galveston County jail.
Gov. Greg Abbott said there were few prior warnings about the suspected gunman.

Here’s what we know about Pagourtzis, so far.
Social media presence
A Facebook account, which authorities confirmed belonged to Pagourtzis, was taken down just after the shooting. But social media users shared screenshots of posts online.
On April 30, Pagourtzis shared a photo of a black shirt with the words “BORN TO KILL” written on the front.
An Instagram account linked to the suspect, which has also been removed, showed a photo of a gun and knife.
Pagourtzis was a dancer, member of church
Pagourtzis played on the school’s junior varsity football team, and was a member of a dance squad with a local Greek Orthodox church.
Father Stelios Sitaras of Assumption of the Virgin Mary Greek Orthodox Church in Galveston spoke with the Associated Press about meeting Pagourtzis.
Sitaras said he met Pagourtzis when he danced with a group as part of an annual festival in October. He said the Pagourtzises are members of a nearby parish.
“He is a quiet boy,” the priest said. “You would never think he would do anything like this.”

The Associated Press also reached out to the suspect’s family, who declined to comment on the deadly shooting.
A woman who answered the phone at a number associated with the Pagourtzis family said: “Please don’t call us. Give us our time right now, thank you.”
During a press conference Friday, Abbott said the teenager likely obtained the weapons used in the shooting from his father who legally owned them.
Ongoing investigation and calls for action
Abbott confirmed that two weapons – a shotgun and a handgun – were used in the shooting.
Officials said search warrants were carried out at the alleged shooter’s home. Investigators located information from journals, computers and a cellphone where Pagourtzis said he wanted carry out a mass shooting, then commit suicide.
This is the largest school shooting in the U.S. since the Parkland, Florida incident in February when 17 were killed.
