He

- "He had come this far, he wasn't just going to stop now. When he looked back on it he had done everything wrong, literally everything. He had made the wrong choices, he had talked to the wrong people, he had been at the wrong places, he had done everything wrong."-

He is a boy who is not happy with his life, so he takes it. Alva finds his dead body and calls the police. They take his body away, but his ghost follows Alva around.
