The Santa Fe High School in southeast Houston joined the long list of United States' campuses, where students and faculty have been killed by gunmen.
The 17-year-old teen, Dimitrios Pagourtzis, who opened fire at his own school was a quiet loner, his classmates told.
Pagourtzis' spray of gunfire on Friday killed nine students and a teacher. This incident once again puts the spotlight on the need for stricter gun laws.

After shooting, Pagourtzis wanted to commit suicide
Pagourtzis is said to have obtained the shotgun and pistol from his father. Texas Governor, Greg Abbott said his father is likely to have acquired weapons legally.
Initial probe revealed Pagourtzis wanted to commit suicide after the shooting. "He didn't have the courage to commit suicide," Abbott said.
At a brief court hearing on Friday, Pagourtzis was charged with capital murder and was denied bail.
Shooter wanted his story to be told, spared closed ones
Investigators revealed Pagourtzis refrained from killing people he was close to, as he wanted his story to be told.
They also discovered a T-shirt on Pagourtzis' Facebook page that read, 'Born to Kill'. However, there were no definite signs that he was planning an attack.
"Here, the red flag warnings were either non-existent or very imperceptible," Abbott told reporters.
