A ransom note was found and the police need your help. They are backlogged with work and hopes your knowledge of chemistry can be put to use. There are three suspects who wrote the ransom note, and
their pens have been confiscated. To protect their identities, we'll refer to these students simply as
Suspects 1, 2, and 3. Suspect 1 had the permanent marker. Suspect 2 had the black crayola. Suspect 3
had the black Vis A Vis marker. Determine which suspect's pen, if any of them, was used to write the
ransom note.
