The Indiana Occupational Safety and Health Administration will assist in the investigation , which will include a reconstruction of the accident . Notre Dame will hold a special Mass Thursday evening in memory of Declan Sullivan , 20 , who died Wednesday afternoon when the scaffolding toppled in strong winds .
