A school shooting at a Florida high school that killed 17 people and injured 15 on Wednesday is the 17th school shooting in the U.S. this year, a gun advocacy group reports.
Authorities say Nikolas Cruz, 19, confessed to the mass killing at Marjory Stoneman Douglas High — the worst school shooting in Florida history, according to police accounts released Thursday, the Miami Herald reported. He was held without bond at his first court appearance on murder charges, The Herald said.
There have been at least 16 other U.S. school shootings in 2018, according to data from gun control advocacy group Everytown for Gun Safety.
But what the group defines as a “school shooting” is disputable, The Washington Post reported. Everytown says a school shooting occurs "any time a firearm discharges a live round inside a school building or on a school campus or grounds."
Never miss a local story.
Five of the 17 school shootings, which originally listed 18, for 2018 happened during school hours and resulted in any physical injury, The Post said.
The most recent school shooting took place Feb. 1 in Los Angeles, when a 12-year-old female student allegedly opened fire inside a middle school classroom, leaving four students injured, Fox News reported.
A 15-year-old student opened fire last month inside a rural Kentucky high school, authorities said, killing two of his classmates and injuring dozens, the Associated Press reported.
Clarification: The statement that there have been 18 school shootings so far in 2018 was based on information from the organization Everytown for Gun Safety, which defines a school shooting as “any time a firearm discharges a live round inside a school building or on a school campus or grounds.” Not all of those instances occurred doing school hours and/or involved students.
