Timothy "Tim" Carter (at first time called Ross / Red John, in the early draft of the screenplay), then also known as "the Fake Red John", was a Red John pretender. He was only a mysterious criminal man - one of Red John's accomplices -, young girl abductor (with his wife and, maybe, Red John's helping), and probably sex offender and rapist. His official job is businessman, but this identity is fake. He was killed by Patrick Jane, believing Timothy is Red John. Patrick is absolved by murder at trial, because Carter has a gun and threatened Jane with it. As the prosecutor says at trial, it's not known if Timothy had killed anyone in his past life.
