 Although the crime scene was cordoned off, the police were unable to remove the bodies or inspect the area due to a sudden snowstorm, therefore the bodies were not taken away until the following morning after they had been checked for booby-trap bombs.When the security forces inspected the scene, they found Kleenex tissue and a Lucozade bottle, but later forensic tests on the items did not find any fingerprints or saliva.Ballistic testing showed that the weapons used in the attack were two .223 Armalite rifles, one Ruger Mini-14 and a 7.62 Short rifle.
