A 9-year-old boy stabbed his older brother to death with a steak knife during "horseplay," authorities said.
Travis Sutton, 11, was stabbed once in the chest on Saturday and died later at a hospital, sheriff's Deputy Bob Killeen said.Authorities weren't sure whether a woman who was baby-sitting the two boys and her own 11-year-old son was in the house at the time of the killing.
The 9-year-old had not been charged but remained in custody early today.
