Authorities say a Wisconsin bus driver won't be charged criminally in the death of a 12-year-old boy.

Police say drug and alcohol tests for the 61-year-old Appleton man who was driving the bus came back negative.

Seventh-grader Justin Johnson was struck and killed by the bus on Sept. 6 as he walked home with friends after the first day of class in Kaukauna. The boy attended River View Middle School.

WLUK-TV reports police say the bus driver faces a citation for failing to yield to a pedestrian. The citation carries a fine of $98.
