LEBO ? Coffey County officials say that they still have not determined what started a fire that killed two adults and two children in eastern Kansas.

County Undersheriff Ken Roney says all four of the victims in Saturday’s fire at a mobile home in Lebo died of smoke inhalation.

The blaze apparently started in the front of the mobile home.

The victims were 25-year-old Michael O’Clair, 28-year-old Heather Super, 5-year-old Tafani Merrell and 2-year-old Taylan Super.

Roney told Emporia radio station KVOE that O’Clair and Super were an unmarried couple. Super was the mother of the two children and was pregnant when she died.

Tafani’s father, James Merrell, lives in Ottawa.
