Dimitrios Pagourtzis, 17, is being held on a capital murder charge stemming from the shooting on Friday in Texas

The 17-year-old gunman accused of killing ten in a cold-blooded shooting rampage at his high school has appeared in court for the first time, as cops race to find potential hidden bombs.

Dimitrios Pagourtzis shuffled before a judge in Galveston, Texas on Friday, to hear his rights and the charges against him.

'Yes sir,' he replied softly two times in a row to confirm that he is a US citizen and would be requesting a court-appointed attorney.

Asked if he was out on bond on any other charges, Pagourtzis, who has no known criminal record, quietly replied 'No sir' to the judge.

Pagourtzis was denied bond. He is being held in solitary confinement in the Galveston County jail on charges of capital murder and aggravated assault of a peace officer. He did not enter a plea in his initial appearance.

The accused killer hung his head during the appearance and was clad in a drab green prison outfit, handcuffed and surrounded by deputies.

If convicted he would face the death penalty.

According to court documents, Pagourtzis confessed to the shooting and also said he spared the students he liked so he could 'have his story told'.

Pagourtzis was clad in a 'Born to Kill' T-shirt and black trenchcoat when he embarked on his rampage during first period at Santa Fe High School in Texas on Friday morning, yelling 'Surprise!' while brandishing his father's shotgun and pistol, before opening fire and gunning down eight students and two teachers, police say.

He subsequently surrendered when confronted by police, who say he backed out of his original plan to commit suicide at the end of the massacre, but not before planting explosives around the school.

On Friday afternoon, Texas Governor Greg Abbot said that cops had recovered 'various kinds of explosives,' including a 'CO2 device' and a Molotov cocktail in a home and a vehicle. He added there is 'potential for explosive devices in other sites being investigated.'

Authorities were searching a trailer home associated with the family about three miles from the school on Friday afternoon.

'Please don't call us. Give us our time right now, thank you,' said a woman reached by the Associated Press at a phone number associated with the Pagourtzis family.

The confirmed fatalities from the shooting so far include substitute teacher Ann Perkins, 64, art teacher Cynthia Tisdale and students Sabika Sheikh, Chris Stone, Kim Vaughan, Angelique Ramirez, Aaron Kyle McLeod, Christian Garcia and Shana Fisher.

As well as killing 10, the shooting spree also injured 10 more, including John Barnes, 49, a retired Houston police officer now working as the Santa Fe resource officer who was first to confront the shooter. The hero cop was shot in the arm and was hospitalized in critical condition.

Officials also questioned two other students who were detained after the shooting. At least one was held because of 'suspicious reactions' to the shooting, Abbott said.

They have not been named or charged, and investigators subsequently indicated that Pagourtzis had confessed that he acted alone.

Police are now trying to piece together what motive 'quiet' Pagourtzis had for carrying out the shooting.

Abbott said Pagourtzis wrote about planning the attack in journals on his computer and in his cellphone that police obtained.

'Not only did he want to commit the shooting but he wanted to commit suicide after the shooting,' Abbott said, adding that Pagourtzis told authorities he 'didn't have the courage' to take his own life.

On his now-deleted Facebook page, Pagourtzis shared a photo of a black T-shirt with the words 'Born to Kill' printed across the front on April 30. The suspect is believed to have been wearing the same shirt and combat-style boots when carrying out the massacre.

Other photos shared on Pagourtzis's page the same day in April depicted a dark-colored trenchcoat festooned with various insignia, including the Nazi Iron Cross, which the teen wrote stood for 'bravery.'

Additional patches on the garb included the rising sun, a Communist hammer and sickle pin and a depiction of the idol Baphomet, which Pagourtzis said symbolized 'Evil.'

A week prior, a photo showing a handgun and a knife appeared on an Instagram account associated with Pagourtzis. The page has since been taken down.

Students at Santa Fe High told NBC News that Pagourtzis wore a trenchcoat to school every day.

Dustin Severin, 17, told KPRC-TV he saw Pagourtzis in the hallway before the shooting wearing his 'usual outfit.'

Severin says the teen has been picked on by football coaches 'for smelling bad',' and he described Pagourtzis as someone who keeps to himself.

Tristen Patterson, 16, who introduced himself as a friend of Pagourtzis', said he is interested in guns and war simulation video games, but that he has never about talked about killing people.

He also claimed that the high school junior did not show signs of bullying, but would sometimes enter the classroom 'acting a little bit down or sad. A little bit sluggish.'

Pagourtzis plays on the Santa Fe High School junior varsity football team, and is 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, Texas, said he met Pagourtzis when the young man danced with a group as part of an annual festival in October. He said the Pagourtzises are members of a nearby parish.

Sitaras said he had never heard of the teen being in any sort of trouble.

'He is a quiet boy,' the priest said. 'You would never think he would do anything like this.'

Michael Farina, 17, said he grew up with Pagourtzis and would play video games with him. He said Pagourtzis knew a lot about guns and remembered him asking which one he should get when he was older.

'I'm kind of dumbfounded. We didn't get any warning,' Farina said.

He said a black trench coat and black boots was Pagourtzis's regular outfit to school. 'I guess you could say it was his kind of style,' Farina said. He said he wasn't someone who got into trouble and described him as a 'run of the mill' student.

At a press conference this afternoon, Governor Abbott said the suspect used his father's legally owned shotgun and .38-revolver, but it's not clear whether the father knew his son had taken them.

The suspect's father Antonios Pagourtzis, 63, runs a ship repair and industrial cleaning firm. The elder Pagaourtzis was born in Greece and 'liked' NRA spokeswoman Dana Loesh on Facebook.

According to the governor, explosive devices including a molotov cocktail had been found in Dimitri Pagourtzis' home in Alvin and a vehicle as well as around the school and nearby.

The governor says the suspect said he originally intended to commit suicide, as he had written in journals found on his computer and cellphone, but gave himself up and told authorities that he didn't have the courage to take his own life.

Dr. Safi Madain at Clear Lake Regional Medical Center says six shooting victims have been treated and released. Madain says one patient remains in critical condition and the other is in fair condition. All appeared to be high school students with gunshot wounds.

Other victims have been treated at the University of Texas Medical Branch in Galveston. Dr. David Marshall, chief nursing officer, says Santa Fe school resource officer John Barnes is in stable condition Friday afternoon.

Marshall says a bullet hit Barnes' arm, damaging the bone and a major blood vessel around his elbow. He says the blood vessel has been repaired, and that Barnes is expected to emerge from surgery within a few hours.

Houston Police Chief Art Acevedo tweeted that Barnes, who is married, was sworn in as an officer in 1995 and retired from the force this past January.

'I heard boom boom boom and my friend got shot': Harrowing accounts from inside Texas school during deadly shooting massacre that killed up to ten students Santa Fe High School student Dakota Shrader described, through tears, how she fled from the gunman who opened fire and killed up to ten of her classmates on Friday Harrowing witness accounts have emerged from inside the Texas school where up to ten students died today after a shooter opened fire in an art class. Students described the initial confusion as the fire alarm went off at Santa Fe High School before shots rang out and students fled from the school buildings into nearby streets and woodland. 'As soon as we heard the alarms, everybody just started leaving following the same procedure as [a] practice fire drill,' student Dakota Shrader told CBS News through tears. 'And next thing you know, we just hear three gunshots, loud explosions, and all the teachers are telling us to run. 'You could just hear "boom, boom, boom" so I just ran as fast as I could to the nearest forest to hide and call my mom.' The gunman, who has now been taken into custody, burst through the door of the first-period art class at around 8am and yelled 'Surprise!' before opening fire. Shrader is comforted by her mother Susan Davidson following the mass shooting at Santa Fe High School on Friday A student who saw him walking down the hallway managed to pull the fire alarm before running away. 'My friend said he saw some kid walking down the hallway with a gun so he pulled the firearm and ran out,' a senior called Tyler Turner told KTRK-TV. 'The teachers told everybody to run after three shots were heard so we all took off and ran into the trees 'Then we heard four more shots so jumped the fence into some dude's house and ran into a car wash. Tyler Turner, a senior at Santa Fe High School, said one of his friends pulled the fire alarm when he first saw the shooter walking down a corridor with a gun 'While we were sitting down trying to figure out what had just happened I saw a girl who had been shot in the kneecap.' 'I heard so many people saying there were gunshots and that people were dead,' fellow student Megan Hunter added. Another student told KTRK in a telephone interview that the gunman came into her first-period art class and started shooting. The student said she saw one girl with blood on her leg as the class evacuated the room. 'We thought it was a fire drill at first but really, the teacher said, "Start running," the student told the television station. The student said she did not get a good look at the shooter because she was running away. She said students escaped through a door at the back of the classroom. Another student, called Paige, offered up a different perspective on today's shooting. When asked by local network ABC13 if she was surprised at the massacre, the girl replied, 'No, I wasn't, it's been happening everywhere and I've always felt eventually it would happen here too.'

Police responded to the school on State Highway 6 near Morning Glory Drive in Santa Fe just before 8am after getting reports of shots fired.

Witnesses described how the unnamed gunman burst through the door of a first-period art class and yelled 'Surprise!' before opening fire on his classmates.

Then a fire alarm was pulled somewhere in the building, sending students running into the hallway.

'As soon as the alarms went off, everybody just started running outside,' sophomore Dakota Shrader told reporters, 'and next thing you know everybody looks, and you hear boom, boom, boom, and I just ran as fast as I could to the nearest floor so I could hide, and I called my mom.'

Another student told ABC13 in an earlier phone interview that the suspect came into her first-period art class and started shooting at 7.45am.

The student says she saw one girl with blood on her leg as the class evacuated the room.

'We thought it was a fire drill at first but really, the teacher said, 'Start running,'' the student told the television station.

The student said she didn't get a good look at the shooter because she was running away. She said students escaped through a door at the back of the classroom.

Santa Fe Police, Galveston County Sheriff's Office and ATF agents responded to the school. Medical helicopters were pictured in the parking lot, along with multiple ambulances.

President Donald Trump addressed the latest school shooting in a tweet, which said in part: 'Early reports not looking good. God bless all!'

First lady Melania Trump, who is still recovering from a recent surgery, also tweeted, saying: 'my heart goes out to Santa Fe and all of Texas today.'

Trump again weighed in on the massacre in Texas as he delivered remarks during the Prison Reform Summit at the White House, expressing his 'sadness and heartbreak' and saying that his administration is closely monitoring the situation.

'This has been going on too long in our country – too many years, too many decades now,' he went on to say. 'We grieve for the terrible loss of life and send our support and love to everyone affected by this absolutely horrific attack to the students, families, teachers and personnel at Santa Fe High.

'We're with you in this tragic hour and we will be with you forever. My administration is determined to do everything in our power to protect our students, secure our schools, and to keep weapons out of the hands of those who pose a threat to themselves and to others.

'Everyone must work together at every level of government to keep our children safe. May God heal the injured, and may God comfort the wounded, and may God be with the victims and with the victims' families. Very sad day. Very, very sad.'

Santa Fe High School has more than 1,400 students in grades 9-12. The senior class was scheduled to graduate on Sunday.

In late February, the school was briefly put on lockdown over 'popping sounds' thought to be gunshots that were heard outside. Police arrived on campus to investigate but no threat was found.

CNN reported that Santa Fe is the 22nd school shooting so far this year, and the deadliest one since Parkland.
