Harnoko Dewantoro

Harnoko "Oki" Dewantoro (November 3, 1964) is an Indonesian serial killer who killed three people in Los Angeles, California, between 1991 and 1992. Despite committing the crimes on the territory of the United States, he was convicted of all three murders by an Indonesian court and sentenced to death, but paroled in 2019 following a clemency from President Joko Widodo.

Biography Born on November 3, 1964, as the son of a prominent Indonesian banking family, Dewantoro and his girlfriend came to the United States on student visas in the late 1980s, initially settling in Kansas, where he attended school. About a month later, he repeated the act with his 26-year-old brother, Eri Triharto Dharmawan, whom he also bludgeoned to death at an apartment in West Los Angeles.

During his interrogation by Indonesian authorities, Dewantoro confessed that he had indeed killed Aswan and Dharmawan, but denied killing Mirchandini, claiming instead that his brother had killed him in a dispute. In an act of cooperation, detectives Ted Ball and Ed Ramirez, as well as 14 other individuals, traveled to Indonesia, where they would serve as witnesses in the trial. On November 20 that same year, he was pardoned and allowed to leave prison on conditional parole. This theory was put into question by Dewantoro's former lawyers, Ruhut Sitompul and Henry Yosodiningrat, who were only aware that their client had had a daughter.
