You are a police investigator. A distraught wife appears at the local police station and states that her husband has just informed her that he has been putting poison in her coffee for over a week. She also states that she was not feeling well and went to the doctor, who advised her that she had indigestion. Her husband confesses to you that he hates her, wants her dead, and has been putting a poisonous substance in her coffee for the past week. Upon investigation, you obtain the substance from the husband. The lab analyzes the substance and advises you that it is harmless.
a. Do you trust that this is the substance that was used? What else will you do to determine this?
b. If the substance was harmless and could not possibly poison the wife, with what crime(s), if any, will the husband be charged?
