You find a note written in black ink by the victim that he had stolen and sold a valuable gold bracelet for $750,000, but he cannot live with what he did. Near the victim, is a pen with black ink. **Did the victim write the note? Describe a technique you have learned in this unit to help you decide whether or not the victim wrote the note.** (hand writing experts are not available). Also, in a notebook, you find these numbers next to the word bracelet: mass 255g, volume 20mL, density 12.75, and melted in autoclave at 300oC. You know that gold has a density of 19.3g and melts at 1,947oC. **Did the victim commit suicide because of his greed or did something else occur? Explain you reasoning.** ||
