On the morning of her 59th birthday, June 9, 1997, Bongak 'Jackie' Koja set out from her home on Mie Place in Oahu, Hawaii, for her customary pre-dawn walk. It was a routine she followed diligently, typically starting at 3:00 a.m. and covering a path to California Avenue, past Leilehua High School, and toward the Wahiawa Hongwanji Mission before heading back home.
She was a woman of habit and a caring wife to her husband, who relied on her for daily assistance due to his arthritis, and a devoted owner to her four dogs. On this particular morning, however, she did not return. The quiet of the early hours was reportedly broken around 4:00 a.m. by screams, which neighbors at the time dismissed as the sounds of rowdy teenagers. This assumption would later prove to be a tragic misinterpretation of a devastating event unfolding in the darkness.
As the sun rose, the first signs that something was terribly wrong began to surface near Leilehua High School. At approximately 7:10 a.m., a janitor discovered a significant amount of blood on a concrete walkway. Believing it to be a prank, he washed the area clean. It was only after news of Koja's disappearance spread that a witness who had seen the janitor cleaning the area contacted the police. A subsequent search by law enforcement uncovered a grim trail of evidence. A trail of blood led to a dumpster behind the school, and in a trash can at a school bus stop, an employee found and discarded Koja's headphones and can of pepper spray. In front of the school, investigators found a piece of her dental bridgework and broken pieces of eyeglasses that matched her prescription, painting a violent picture of her final moments.
The investigation quickly led to a man named Frank Janto, who had a significant criminal history. He voluntarily came to the police and confessed to the brutal attack, stating he had ambushed Koja during her walk while under the influence of drugs. Janto admitted to beating her to death, dragging her body, and disposing of it in the school's trash bin. Tragically, by the time he led law enforcement to the location, the dumpster had been emptied, and its contents were taken to be incinerated. In April 1998, Frank Janto was convicted of second-degree murder for Koja's death and was eventually sentenced to a minimum of 75 years in prison. Despite his confession and conviction, Bongak Koja's remains have never been found and are believed to be unrecoverable. The case stands as a harrowing example of a life cut short by a random act of violence, leaving a family to grieve without the solace of a final resting place for their loved one. The investigation into Koja's murder also led authorities to solve another cold case, as the method of operation was strikingly similar to the 1987 killing of another woman, Rose Chiquita.Last Seen: Jun 9, 1997
