Kriegman and Gabriel move to the east cafeteria where they attempt to ignite a homemade bomb. After a first failure, they destroy a cash register with
second pipe bomb. Kriegman fires on a vending machine. This attracts Officer Halstrom's attention; she stops her cruiser, disembarks and tries to find the
