Doctor Courtney Sithe was the newly-established head coroner of Scotland Yard. She had actually been Asman's true killer, and turned what had ended in an attempted murder into a successful one. Defeated, Sithe slammed her fist on the witness stand, while telling those present that they had no idea what it was like protecting the Professor case all those years. She, along with Drebber, were arrested and sent to prison. Likely as a result of her sensitive knowledge of the Professor incident, Sithe was forbidden from having visitors. This ban was later lifted after the entire truth of the Professor case surfaced. Courtney Sithe, then known under the surname Stevens, was once the second assistant of Doctor John Wilson, along with exchange student Yujin Mikotoba. The two were present during the autopsy of Klint van Zieks, the supposed final victim of the infamous "Professor." When neither Mikotoba or Stevens were watching, Wilson supposedly found the ring of Genshin Asogi in the victim's stomach; in truth, this was a forgery to frame Asogi and protect the identity of the true Professor, Klint. Though Mikotoba had some reservations, the ring was used as decisive evidence to arrest Asogi. [Taken from her Ace Attorney Wiki page.]
