Four people were killed and seven were injured in Tuesday's shooting at Oxford High School in Oakland County — the deadliest U.S. K-12 school shooting since 2018.
Nationwide, there have been more school shootings with injuries or deaths this year, but fewer people were killed or injured than in 2018.
Three school shootings contributed a large share to the number of people killed or injured in 2018: Marjory Stoneman Douglas High School in Parkland, Florida; Santa Fe High School in Santa Fe, Texas, and Marshall County High School in Benton, Kentucky.
Mark Bryant, executive director of the Gun Violence Archive, a nonprofit formed in 2013 to track gun violence in the U.S., said more shootings should be expected as students return to the classroom after a year — or more — of remote learning.
"I think that as we get back to the normalization of the school year … we're going to continue to see more shootings," Bryant said. "It reflects the growing patterns that we're seeing with adults: more guns available, more guns not secured, more guns sold on the streets and that equals more shootings."
In Michigan, 10 shootings causing injury or death have taken place at K-12 schools since 2014. The 15-year-old high school student's shooting spree on Tuesday was the most lethal. In total, six people were killed and 18 were injured at Michigan schools during the roughly eight-year time span.
An additional six school shootings with no injuries or fatalities took place during the same time period in Michigan.
School shootings that resulted in no injuries or fatalities — despite the discharge of a weapon — include an incident at Oxford High School on Oct. 3, 2017. An Oakland County sheriff's deputy's holstered gun was discharged inside the school when a then 18-year-old student struggled with the deputy during an arrest.
