GRAND RAPIDS, Mich. — A court document says a 12-year-old boy accused of fatally stabbing a 9-year-old boy on a western Michigan playground told authorities he wanted to go to jail and did not know the victim.

The Grand Rapids Press reports a delinquency petition filed Friday in Kent County Circuit Court says the 12-year-old told investigators he's "bad and always does stupid things." He added he thought he'd be killed "for doing something like this."

A message was left for the boy's attorney, Charles Boekeloo, who entered a not-guilty plea for his client Tuesday, a day after the stabbing of Michael Connor Verkerke in Kentwood, near Grand Rapids.

The Associated Press couldn't obtain a copy of the document because the court was closed. The AP isn't naming the boy.
