Investigate a brutal death and its connection to an urban legend

A student has been found dead! His head was covered with a paper bag with an eerie smiling face drawn on it—much like the victims of Emio, the Smiling Man—a killer of urban legend who is said to place such a bag over his victims’ heads.

As an assistant private investigator, you are tasked with helping police solve this crime, which is reminiscent of a series of unsolved murders from 18 years ago. Has a serial killer returned, or is this the work of a copycat? Are these crimes inspired by the Smiling Man story, or the origin of it?
