Detention (S03E12)

When a small piece of a note is found, Rush and the team reopen the 1994 death of a teenager that was previously classified as a suicide. After several interviews with local neighbors and childhood friends, it seems the teenager jumped off the roof of his school to his death. The depressed teen was obsessed with Kurt Cobain's suicide and had called into a crisis hotline for help numerous times, all pointing to a clear suicide. However, Rush pursues a new angle that she won't relinquish. (Warner Bros. UK)
