Ten people have been killed when a student opened fire Friday morning inside Santa Fe High School in Santa Fe, Texas.
KHOU-TV in Houston reports that Texas Gov. Greg Abbott confirmed that 10 people have died in the attack that occurred Friday morning. Another 10 people were injured, including a school district police officer, who is in critical condition, Abbott says.
The suspected shooter has been identified as Dimitrios Pagourtzis, 17. He is in custody at the Santa Fe Police Department.
The shooter opened fire in an art classroom. Harris County Sheriff Ed Gonzalez told reporters most of those who lost their lives were students.
The Santa Fe Independent School District says authorities have found explosive devices at the school and off campus.
Abbott said at a news conference that the attacker was armed with a shotgun and a .38-caliber revolver. The shooter's father is believed to be the owner of the weapons.
Police also were working to find and defuse several explosive devices that are believed to have been left in homes and vehicles.
KTRK-TV reports that a suspect has been taken into custody.
Abbott says that police have recovered journals and other information on the attacker's cell phone that spell out his intention to carry out the attack. The material also indicated that he had planned to commit suicide before he could be arrested.
Investigators also are interviewing two other persons of interest, including one person who was at the scene of the attack who "may have had some level of involvement in the crime," Abbott says.
