The St. Joseph News-Press reports the boy was one of three minors investigated in the death of 14-year-old Cameron Satterley. Investigators believe Satterley died in a house fire on Feb. 20 but his body was not found until April 25.
At a hearing Tuesday, the 10-year-old was placed in the care of state social services. Chief Juvenile Officer Linda Meyer said the length of time the boy will be committed has not been determined.
A judge ruled in September enough evidence existed to show the boy committed involuntary manslaughter and arson.
A case against a 12-year-old is pending. The case against a 15-year-old was dismissed in May.
