A Roseville police officer is being called a hero after he ran into oncoming traffic to save an 8-year-old boy with autism. Officer Donald Mason was headed north on Foothills Boulevard Saturday morning when he saw the little boy run into the road. "I was about 20 yards from that intersection," Mason said. "I just saw a little kid in green pajamas darting in the road -- and there's traffic going both ways. Cars were kind of locking up their brakes, kind of swerving out of the way -- and the kid was just b-lining toward McDonald's."
