RACINE, Wis. (AP) -- Racine fire officials say a woman who was hooked up to an oxygen tank has died after a fire started in her apartment bedroom.
The 56-year-old woman was found dead early Friday. Her name hasn't been released.
Fire Lt. Jeff Perkins says the fire was small, but he adds that firefighters who opened her door were met with "very thick black smoke."
Perkins says there are no signs of foul play. He speculates the fire may have been accidental.
A Journal Times of Racine report says there were several oxygen tanks in the room. Perkins says the fire didn't reach any of them, and none exploded.
Two other residents of the four-unit building have been displaced. One unit was vacant.
