An investigator needs fingerprints from a knife recovered from a crime scene and prepares the submission for the FBI Crime Lab by placing the knife into a cardboard box after it is secured to a rigid board. The invoice, transmittal form, and property receipt are also secured inside the box, which is sealed and sent to the crime lab. What can be said about the process used to ship the evidence to the crime lab?
◦ The process used was improper because the knife should have been placed in a plastic bag first to ensure that DNA was preserved.
◦ The box used should have been sprayed with a stencil indicating "FRAGILE" but otherwise the process was correct.
◦ The process used was proper.
◦ The process used was improper because the invoice should have been affixed to the outside of the box.
