A new study that analyzed 156 cases of children in St. Louis injured by guns found that more than 70% of cases involved victims “shot outdoors by an unknown shooter, the motivation of which was unknown.” The study’s lead author Dr. Mary Beth Bernardin discusses why scientists need to better understand why and how children are shot. Dr. Lindsay Clukies, an emergency medicine physician at St. Louis Children’s Hospital, connects the study to what she sees while treating patients.
