As the nation continues to grieve the loss of 17 high school students in the mass shooting in Parkland, Florida, Cronkite News took a deeper look into just how many deaths among Arizona children involve firearms.

According to a 2017 report by the Arizona Child Fatality Review Program, firearm-related fatalities increased by 29 percent from 2015 to 2016. Firearm-related deaths accounted for 5 percent of all child deaths in 2016, and the numbers have steadily increased since. Twelve firearms-related deaths were suicides; 24 were homicides.

A review team has determined that all firearms-related deaths are preventable, and they represent 11 percent of all preventable deaths.
