Criminalist Matt Hughes arrives at the scene of an explosion. He first carries out a search of the periphery of the crime scene, questions several witnesses, and then locates the crater caused by the blast. After finding the crater, he uses a sifter to separate the debris at the site for evidence. Any large pieces of detonators or foreign materials that did not fall through the mesh are collected and packaged in small paper bags. Large, jagged pieces found in the crater are wrapped in paper then placed in another paper bag. What mistakes, if any, did Matt make in collecting and storing this evidence?
