My 9-year-old great nephew, Grady, was shot and killed with an unsecured semiautomatic handgun by another boy. Since that time, so many things have changed for our family. His mom and grandma, my niece and sister, will never be the same. In an effort to keep his memory alive and also to help prevent this tragedy from happening to others, my daughter and I both joined Moms Demand Action in 2016. Grady’s life was cut short because irresponsible adults left a firearm where children could access it. We miss Grady every day.
