Gunman opens fire in Texas school shooting leaving 10 people dead

A 17-year-old boy with a shotgun and revolver has killed 10 people and injured 10 others at a Texas high school, authorities say.

The suspected gunman, who is in custody, also had explosive devices, including a Molotov cocktail, that were found in the school and nearby, said governor Greg Abbott.

He said the assault was “one of the most heinous attacks that we’ve ever seen in the history of Texas schools”.

The governor said the assailant intended to kill himself but gave up and told police that he did not have the courage to take his own life.

A law enforcement official identified a person in custody over the shooting as Dimitrios Pagourtzis, 17.

Another 10 people were wounded at the school in Santa Fe. One was listed in a critical condition and another in fair condition.

Michael Farina, 17, said he was on the other side of campus when the shooting began and thought it was a fire drill. A principal came rushing down the hall telling everyone to run. Another teacher yelled: “It is real!”

Pagourtzis, who is charged with murder, 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.

The suspect used a shotgun and .38 revolver obtained from his father, who owned them legally, Mr Abbott said last night.

One or two other people of interest were being interviewed about the shooting, Mr Abbott said.
