WELEETKA, Oklahoma -- Family and friends said goodbye to the two youngest victims killed in a Weleetka house fire Monday.
Three-year-old James Southern and his 2-year-old sister Barbara were laid to rest Saturday. Their mother said the two were buried together in the family cemetery in Bryant.
The two were staying with a babysitter on Monday when a fire started in the home, killing two other children and two adults inside. Renee Buck, her daughter LaToya Bush and Bush's two children, Tristin and Kurstyn Pelegrin, also died in the fire.
A joint funeral was held for the four on Thursday.
Investigators said they think the fire may have been started by an electrical problem in the living room.
Eight-year-old Tavis Southern was the survivor in the home.
