Coroner Butch Benedict has identified all three workers who died after a construction site collapse at the Hattiesburg-Forrest County Industrial Park.
The three men's names are: Leonardo Navarro Diaz, 30, of Sumrall; Brandon Edward Rathbone, 19, of Hattiesburg; Wayne Dale Kelly, 55, of Columbia.
All three men have worked for American Air Specialists, formerly known as Tucker Heating and Air.
The three workers were buried alive and crews attempted to excavate them by hand early around 10 a.m.
The incident took place near Kohler Engine Co. where a Sam's distribution center is under construction.
The men were completing work on a sewer line, according to Hattiesburg mayor Johnny DuPree.
