The Kansas State Fire Marshall's office and Winfield fire authorities spent Sunday investigating an apartment fire that killed a Winfield man late Saturday.
The fire broke out shortly after 10 p.m. in the 500 block of East 11th in Winfield.
The Winfield man's name has not been released.
An autopsy has to be completed, but authorities believe the Winfield man in his mid-50s may have succumbed to smoke inhalation, Winfield Deputy Chief Fire Marshall Alan Stoll said.
No working smoke detectors were found in the apartment, Stoll said. The fire and smoke caused $8,000 to $10,000 in damages.
