I need an explanation for this Law question to help me study.

You are completing an internship at a defense attorney’s office during your senior year in college. After graduation you plan to enter law school and pursue a career as an attorney, although you have not yet decided what type of law to practice. Your duties as an intern are to assist the private practitioner you work for in a variety of tasks, including interviewing clients and witnesses, organizing case files, running errands, and photocopying.

A case that you are helping with involves a defendant charged with armed robbery. One day while you are at the office alone, the defendant comes in and gives you a package for the attorney. In it you find a gun. You believe, but do not know for a fact, that the gun is the one used in the armed robbery. When the attorney returns, he instructs you to return the package to the defendant.

What should you do? What should the attorney do?
