LIBERAL ? A weekend fire claimed the lives of two Oklahoma children.

Rowdy Fox, 4, and Chance Fox, 6, both of Hooker, Okla., died in a camper-type travel trailer that caught fire Saturday morning. Preliminary autopsies showed the children died of smoke inhalation.

Liberal Police Department Detective Jason Ott said the children were visiting their father, Bob Fox, in the older model camper trailer that was parked behind a transmission business.

Fox, 53, was in the trailer at the time of the fire and was taken to Southwest Medical Center in Liberal for treatment of nonlife-threatening burns, authorities said. He was still hospitalized Monday.

Deputy Chief Kelly Kirk, of the Liberal Fire Department, said the cause of the fire was being investigated.

The fire was so extensive it spread to Mata’s Transmission, west of the trailer. The heat melted wall and ceiling insulation in the business, Kirk said.

Liberal is just across the Kansas state line from Hooker.

Two Oklahoma children died early Saturday when this camper-type travel trailer caught fire in Liberal. Rowdy Fox, 4, and Chance Fox, 6, were visiting their father.
