School shootings in America: Texas mass shooting was deadliest at a K-12 school since Sandy Hook

• Sandy Hook Elementary School shooting left 27 people dead on December 14, 2012.
• Tuesday's school shooting in Texas is the deadliest K-12 school shooting since Sandy Hook.

A shooting at Robb Elementary School in Uvalde, Texas has left at least 18 students and one teacher dead, making it the deadliest mass shooting at a K-12 school since Sandy Hook.

The Sandy Hook Elementary School shooting left 27 people dead on December 14, 2012, in Newtown, Connecticut. Each of the 20 child victims was aged 6 and 7. On Tuesday evening, the Texas death toll surpassed the 17 people killed at Marjory Stoneman Douglas High School in Parkland, Florida in 2018.

The 20-year-old gunman killed his mother prior to the attack, similar to the suspected shooter in Texas, who is believed to have killed his grandmother before the attack, according to a statement from Texas Governor Greg Abbott.

The Robb Elementary School shooting occurred after 12 p.m. Central Time, two days before the last day of school. The school, located just over 80 miles from San Antonio, enrolled second through fourth graders.

Authorities reported that the 18-year-old suspected gunman is also dead.

Buffalo's mass shooting last week was regarded as the deadliest of 2022, but Tuesday's attack took the title in less than a week.
