SANTA FE, Texas — Ten people are dead and 13 injured following a mass shooting Friday morning at a Houston-area high school. 

  • Texas Gov. Greg Abbott says 10 people were killed and 13 injured
  • One person is custody, one or two people were detained for questioning
  • Two explosive devices were located in and around the school. 

The suspect has been identified as 17-year-old Dimitrios Pagourtzis. The shooting took place at Santa Fe High School, in Santa Fe, Texas, which is located southeast of Houston.

According to the Santa Fe Independent School District, Pagourtzis is charged with capital murder and aggravated assault of a peace officer. He is being held in the Galveston County Jail without bond.

During a press conference at 2 p.m. Friday, Texas Gov. Greg Abbott confirmed the number dead and injured. After thanking law enforcement for their efforts, Abbott called the shooting "one of the most heinous attacks that we've seen in the history of Texas schools." 

Abbott said law enforcement, as of Friday afternoon, was still checking the securing the shooting scene. In addition, they obtained warrants to search two residences. They were being extremely cautious, Abbott said, because of the possibility of explosive devices at those homes. Abbott said two explosive devices, a C02 device and a Molotov cocktail, were located on the campus. 

Abbott went on to say that Pagourtzis, the suspected shooter, turned himself in to police and kept records in journals and his cellphone detailing his plan. The governor said the teen wished to commit a mass shooting and then commit suicide. 

In addition to the suspected shooter, Abbott said, one or two people were being questioned. Abbott stated the shooter used two weapons: a shotgun and a 38 revolver. It's believed the shooter obtained the weapons from his father, who owned them legally. 

Abbott said his goals include gathering evidence to ensure the crime is properly prosecuted and to provide the affected children with counseling and support. 

"We need to do more than pray for victims and families. [We need] to step up and make sure tragedy isn't repeated," Abbott said. 

Abbott said the steps he'll take to ensure tragedy isn't repeated include round table discussions with Texas leaders to begin next week. In addition, he mentioned strengthening background checks, addressing mental health issues behind violence and keeping firearms out of the hands of dangerous people. 

Texas Sen. Ted Cruz, who spoke during the Friday press conference, mentioned the mass shooting at a church in Sutherland Springs, Texas, and the Austin, Texas, bombing attacks that took place in March. 

"Texas, as a state, will make it through this. Santa Fe will make it through this," Cruz said. 

Texas Lt. Gov. Dan Patrick echoed what Abbott said, calling for vigilance. 

"If you're a parent and own guns, lock your guns away," Patrick said. 

Patrick also called for increased security measures at Texas schools. 

"We may need to retrofit schools. There are too many entrances," Patrick said. "We need to harden our schools to make them safer." 

A message on the Santa Fe ISD website issued early Friday morning broke the news about the shooting: “This morning an incident occurred at the high school involving an active shooter. The district has initiated a lockdown at the high school.”

One student told Houston television station KTRK in a telephone interview that a gunman came into her first-period art class and started shooting. The student says she saw one girl with blood on her leg as the class evacuated the room.
