Social media platforms like Facebook and Twitter have become valuable tools for finding missing children. The 21st Century Milk Carton Project empowers families to create content-rich missing person profiles on Facebook that can reach a large international audience at no cost. These profiles often include pictures, videos, and updates that can aid in recovery. Law enforcement also uses Facebook to feature missing persons and connect with online communities dedicated to solving open cases. Similarly, Twitter allows sharing of cases and media in real-time to a large international audience, and has proven effective in locating missing children across borders.
