We all share your/our loss. What a waste to lose a loving family/community members. IMHO, the proximal problem was alcohol, the proximal solution to your daughter's long term alcohol problem was AA and counseling, coupled with structured support. I encourage others with loved one's situated similarly to "push" them into alcohol abstinence and counseling. They will not do it on their own. And, no I'm not a teetotaler - just an astute observer of life. Substance abuse problems rarely fix themselves - it takes not just empathy and sympathy but strength from the family and community village. I'm very sorry for your loss and hope efforts on behalf of your daughter move forward.
