Authorities say a fire that killed five children and their mother at a Michigan motel appears to have been an accident.
The Berrien County sheriff's office says experts found no evidence of an accelerant that would have started the deadly blaze early Saturday at the Cosmo Extended Stay Motel in Sodus Township.
The precise cause still is under investigation.
The fire began in a first-floor room of the two-story motel, about 100 miles from Chicago.
Twenty-six-year-old Kiarre Curtis and five of her children died in a room on the second floor.
The sheriff's office said Sunday that autopsies confirmed all six died of smoke inhalation.
Curtis' husband and a 1-year-old child survived.
The sheriff's office says investigators are also examining the motel's fire alarms and smoke detectors.
