They want more specific witnesses for a couple locations that day with the white truck. Parking near the school at 8:15-8:30, 2 different Fred Meyer store parking lots, 9:00-9:30? and around 10am-10:30 on that day of June 4th, on particular roads near the school area. The also asked about anyone seen in or near the truck. Some witnesses have came forward and they are looking for some more independent witnesses to collaborate on this information.
This is slow tedious work, yet I feel they are doing their best.
