Eight teens are facing charges, and a ninth is still at large, after police say they went joyriding in a stolen van. Police say the incident happened Saturday night, and ended in West Allis. Investigators say the teens, all 17-years-old or younger, sped away from officers after a traffic stop. West Allis police say the van drove over two pairs of road spikes. The 17-year-old suspect who drove the van could face adult charges; the others are being sent to juvenile prosecutors to face punishment.
