The Tokyo District Court on Tuesday sentenced a man to 22 years in prison for killing his teenage ex-girlfriend in 2013, a term unchanged from its initial ruling, in the retrial of a high-profile stalking-murder case in Mitaka, western Tokyo.

The trial of Charles Thomas Ikenaga, 23, followed an unusual course because the indictment in the first trial had failed to mention that he also engaged in “revenge porn” — the posting explicit sexual images — of the victim before and after the killing of the girl, who had ended their relationship.

In handing down the ruling, Noriaki Kikuchi, the presiding judge at the court's Tachikawa branch, concluded that the case was "extremely malicious" in that it "took away the life of the victim and (her) dignity."
