WHEATON, MO (KMOX)-The five people killed in an early morning fire in the small southwest Missouri town of Wheaton, are identified as four adults and a child.  Their names and ages are not being released yet.

Wheaton Volunteer Fire Department Chief Bob Lombard tells KMOX  the blaze in the Blue Ridge Complex on South Hill Street broke out at about 3 am, “It was fully involved in the stairwells and it was already through the roof in the middle and those people who were in those end units didn’t get out.”

Lombard says a man and woman were in one apartment. A man, woman and six or seven-year-old child in another, “It looks like they all probably died of smoke inhalation.”

He says one resident noticed the fire and knocked on doors to wake up the other residents, who got out on their own.  The Red Cross is helping them.

Lombard says he doesn’t know if the building had working smoke detectors.

The State Fire Marshal’s office is looking for the cause.

Wheaton is a town of about 800, 60 miles southwest of Springfield.
