"We had a pretty rough storm blow through at that time, so common sense would tell us it was probably related to the storm, but I'm not a structural engineer," said Greenwood Fire Department Lt. Tom Kite.
The two workers who were hurt were taken to an Indianapolis hospital. Kite said the men were "pretty seriously injured."
The workers were building a concrete block and mortar wall inside a prefabricated structure when the wall collapsed on them. It wasn't clear how high the structure had been built.
The accident occurred in a business park near Interstate 65 south of Indianapolis. The workers were building a freight terminal or warehouse for Dayton Freight Lines Inc., but it wasn't immediately clear whether they were working for Dayton or a contractor.
A message seeking comment was left with the company Thursday.
Pitcher said police would turn over evidence to the Indiana Occupational Safety and Health Administration.
