"We were just touring the building and the stairwell was weak but we did not realize how weak it was until several people had gone down it and then we heard the crash and saw the stairs fall," another visitor at the site named Coby Scherrill recalled to the outlet.
The city's Emergency Management Director, Travis Mullins, confirmed to Fox News that the incident took place on Tuesday.
McEntire confirmed to Fox News that she was at the historical building, but was "safely evacuated."

"While my team and I were in Atoka, OK yesterday checking out an old historical building, a staircase collapsed," the country music star told Fox News in a statement. "Thankfully, no one was seriously injured. We were safely evacuated from the building thanks to the quick response from the Atoka fire and police departments."
Reports say McEntire was checked by paramedics on site and is ok. Reps for McEntire did not immediately return Fox News' request for comment.
McEntire was reportedly checking out the site for an upcoming project but little details were provided as to what exactly the reason for her visit was.
The building is reportedly over 100 years old.
