Everybody thought that the killer was angry and just randomly kicked that box in the bus and dropped his shit there. I thought he did it on purpose. He bailed on the killing because things didn't go according to plan. Even if he killed Kayo right then and there, he couldn't set up his scapegoat (Yuuki) this time since Satoru ruined his first attempt.
I interpreted that as a "Fuck you, I'll be back".
