Dr. Emmy Betz sees first-hand the effects of gun violence in the emergency room at the Anschutz Medical Campus where she works. She also researches gun violence as the head of CU Anschutz's Firearm Prevention Initiative. Betz says by far, the largest number of deaths due to gun violence are the result of suicide and she says it's critical to find ways to keep guns out of the hands of people who are a danger to themselves or others. One tool Betz and her team have developed is a map of places in Colorado where people can temporarily store firearms.
