Who did it? (A horror mystery with a sudden hint of romance)

Meet Samantha Harvest and Jonathan Cameron, two seniors at Kingston High School, California.
Both are very distance from the 'popular' side of the school. Jonathan is more into what his best friend does and, Samantha just wants time to herself in her 'special' room. On a very particular day, a young girl was murdered in the schools hallway. A huge group of kids by the names of Janet and her sister Jacky, David, Max, Lilly, Zach, Harris, Jason, Mark, Elli, Victor, The math teacher, Samantha and, Johnathan. Each one of these kids could be the killer and or, the victim as the killer kills each one of the group. Who will be blamed and, who will survive? The question that everyone asks, who did it?
