A woman died early Sunday morning in a mobile home fire in Butler County.

Crews were dispatched to the fire in 18000 block of SW Santa Fe Lake Road in Douglass at 12:45 a.m. The first firefighter arrived on the scene at 12:52 a.m.

"It's about 6 miles from here and the volunteers have to get up, get dressed, get to the station, get the trucks started and go out there, so it takes a lot of time when you have volunteers," said Butler County Fire District #3 Fire Chief Jim Woydziak.

Chief Woydziak said the home had collapsed due to the fire and only a portion of one wall was standing.

"The people that saw it were passers-by and they stopped at the next driveway and called it in at the address and called it in from there."

After the fire was under control, firefighters discovered the body of 75-year-old Lydia Cox in the rubble. Chief Woydziak said she lived in the home alone.

Investigators determined the fire started in the kitchen, but no official cause has been given. A car in the driveway sustained heat damage. The home is considered a total loss.

Woydziak said in the five-and-a-half years he's worked in Butler County this was his first fatal fire. He said it's not likely the department's response times had any affect on the outcome. Butler County Fire District #3 has paid employees during the week but depends on volunteers in the evenings and on the weekends.

"70% of the United States is covered by volunteer firefighters, our response times are not very good unless you live very close."

An autopsy will be performed on Cox to determine her cause of death.

A total of 14 firefighters responded to the scene plus a fire investigator and several deputies.
