Bentonville police have added another charge against Jonesboro school shooter Mitchell Johnson.

Johnson was arrested and jailed over the weekend on a marijuana charge while awaiting sentencing on a federal weapons conviction.

On Tuesday, police added a theft charge stemming from reported use of a debit card that was left at a convenience store where he had worked. Johnson had a court appearance scheduled Tuesday.

Now 23, Johnson was a boy when he and Andrew Golden were found guilty in juvenile court of killing four fellow students and a teacher at Westside Middle School near Jonesboro in 1998.
