A Bowie County Sheriff spokesman says the body of one child has been taken to the Southwest Institute in Dallas for an autopsy.
Texas Rangers believe injuries to the child are consistent with a homicide.
Bossier City police have arrested the owner of a cheerleading instructional business on felony theft charges after she accepted thousands of dollars from parents for the purchase of uniforms and equipment only to keep the money for herself.
Officials have released the names of the mother and children killed in Wednesday's house fire.
The mother's name is Amanda Doss. The children are 11-year-old Gweneviere Doss and 8-year-old Texas Johnson.
