The Databeccause of a barn fire that killed at 44 horses and seriously injured a man in northwest Ohio remained under investigation Thursday. Meanwhile, online donations from three fundraisers had topped nearly $350,000 to help those affected in the deadly blaze.

The fire broke out over the weekend in Logan County, about 70 miles northwest of Columbus.

The fire was reported to the Logan County Sheriff's Office at 12:15 p.m. Saturday, a dispatcher for the agency told The Columbus Dispatch, part of the USA TODAY Network.

According to information from the Richmond Township Fire Department, the fire destroyed a barn used by two Logan County performance-horse businesses.

"We are waiting on the cause of the fire to be determined by the state fire marshals' office," Fire Chief Dustin Plikerd told USA TODAY Thursday. The origin of the fire also remained under investigation, the chief said, adding foul play was not suspected.

Assistant Fire Chief Jason Johns, who works for the department in Belle Center, said firefighters from three counties responded to Brant Performance Horses, along State Route 638.

"It was too far gone when we got there," Johns said of the 60,000-square-foot-barn with stalls, a performing arena, and living quarters for employees, who lost their belongings.

Johns said crews remained on scene until about 11:30 p.m. Saturday.
