Ten people were killed and at least 10 more were injured after authorities say 17-year-old Dimitrios Pagourtzis opened fire on fellow students at Santa Fe High School in Texas Friday.
A substitute teacher, a Pakistani exchange student and a teen who reportedly spurned the shooter's romantic interests were among those killed, as Pagourtzis allegedly yelled, "Surprise!" and screamed, "Woo hoo!" in what Gov. Greg Abbott called "one of the most heinous attacks that we've ever seen in the history of Texas schools."
Friday's tragedy is the latest school shooting to occur in the United States in recent history. Others include the following:
Marjory Stoneman Douglas High School
Former student Nikolas Cruz, 19, pulled the fire alarm before firing on students and staffers at Marjory Stoneman Douglas High School in Parkland, Fla., on Feb. 14, 2018. Fourteen students and three staff members were killed, while 17 others were wounded.
Virginia Polytechnic Institute and State University
In April 2007, a senior at the university committed the deadliest school shooting in modern U.S. history, killing 32 people and injuring 17 others in two separate attacks on campus — one in a co-ed dormitory and the other in the Engineering, Science and Mechanics building.
Sandy Hook Elementary School
In December 2012, 26 people were killed, including 20 schoolchildren ranging in age from 5 to 6, inside the Newton, Conn., school after a 20-year-old entered and opened fire. The gunman killed his mother before heading to the school. After committing the heinous shooting, he killed himself as police closed in.
University of Texas
On Aug. 1, 1966, a former Marine sharpshooter, 25, opened fire at the University of Texas in Austin. The gunman positioned himself on the observation deck atop the UT Tower and shot his targets one-by-one. He killed 14 people and wounded 31 others. He also killed his wife and mother before the attacks. The massacre ended when police located the shooter and fatally shot him.
Columbine High School
Two high school students, ages 17 and 18, opened fire at the Littleton, Colo., school in April 1999. They reportedly spent weeks prepping for the massacre, killing 13 people while injuring 24. They later committed suicide in the school’s library together.
Red Lake Senior High School
A 16-year-old sprayed the Red Lake Senior High School with bullets in March 2005 after robbing his grandfather of police weapons and a bulletproof vest. He killed his grandfather before heading to the school, where he murdered seven people and wounded five others. He committed suicide after a gun battle with police.
In April 2012, a 43-year-old gunman in California committed Oakland's worst mass killing when he opened fire at the Korean Christian school. Witnesses said the shooter stood up in class and told everyone to get up against the wall while holding a gun. He killed seven people and wounded three others. He fled the school after the murders and later surrendered at a supermarket. The gunman pleaded no contest and is serving life without the possibility of parole.
