In-home firearm homicides of children and teenagers have more than doubled since 2010, a new study suggests.

Nearly a quarter of children and teenagers killed by guns died in their own homes between 2020 and 2021, including two-thirds of child victims 12 and under, researchers wrote in findings published Friday in JAMA Surgery.

These cases are most often associated with murder-suicide (23%); child abuse (20%); and intimate partner violence (17%), the study found.

What's more, children are more likely to die by gunshot in their own home in states with looser gun control laws, additional results reported Friday at an American Academy of Pediatrics' meeting in Denver indicate.
