Criminal prosecution may not be an option against the person responsible for the fire at a Kansas City foster home where two young sisters were killed. She is a nine-year-old girl. Fire department spokesman Brad Humston says the child has admitted lighting some toys on fire. The resulting blaze last Saturday killed sisters Alyah and Alexus Brown, ages 6 and 2. Humston says they’ll wait a couple of days before questioning the girl who set the fire.
