Episode Andy in C Minor
Status Arrested

Carlos Ramirez was a deaf kid, the best friend of Andy Rierdan and ironically his murderer. Despite Carlos having a bit of a temper, he and Andy were close friends. But that friendship started to fall apart when Andy began developing feelings for a girl named Emma Walker, who was volunteering at their school. Unlike them, she was not deaf, and falling for her was the push Andy needed to find a way to get his hearing back. With his father's approval, Andy and Carlos went to a consultation for a cochlea implant. Andy was chosen as a candidate since he lost his hearing at age 7, but Carlos wasn't so lucky. Since he was actually born deaf, the doctors didn't choose him. After Andy received the implant, he immediately went to the school's basement to hear himself play piano. Carlos happened to stumble upon him and witness Andy hear the music. Hurt and jealous, Carlos grabbed the metronome off the shelf above the piano and smashed it against Andy's head in a rage, killing him.
