1. DEADLY CHEMISTRY

2. The Crime
Poor Cynthia had many enemies that she didn’t know about. She was found face down murdered last week in Lab C206. Police couldn’t find any clues besides 8.40 L of a solution next to her body. The detectives on scene soon determined that the solution was one of 2 possibilities: sodium hydroxide or sodium chloride, both of which can cause death if ingested in huge amounts.
