In the weeks following her death, her father Gus filed a wrongful death lawsuit against MGM Resorts International (which operates Mandalay Bay), concert promotor Live Nation, and Slide Fire Solutions, which manufactures the "bump stock" accessory. "We are sickened by how this cowardly shooter was able to purchase 33 guns this last year without raising any red flags," says Adam. "Also, how's it possible to obtain an attachment, such as a bump stock, with no serial tracking and enabling him access to pretty much machine guns which took our Andrea and many other sweet souls away?" Adam hopes the lawsuit raises awareness not just around gun control, but also for better security in places like hotels as well as proper exits out of venues. "Andrea would have wanted this. She had so much going on for herself, and so many dreams, and to have it taken away from this coward," says Adam. "She would have wanted us to go as far as we can to make sure this doesn't happen to someone else."
