Hawaii Man Kidnaps Teen Girl, Forces Her to Smoke Meth, and Assaults Her

Mikella Debina

Court documents say a Hawaiian man who is a repeat offender kidnapped a girl at knifepoint, held her captive in a school bus, made her use meth, and raped her.

According to police reports, Duncan Mahi, 52, approached the 15-year-old victim and her boyfriend on Anaehoomalu Beach on Sept. 16, robbed the couple at knifepoint, tied up the girl’s boyfriend with zip ties while threatening to kill her if he got loose, and kidnapped her.

The girl was led to Mahi’s vehicle and instructed to put on a disposable mask and hat.

“Mahi forced [the victim] to smoke methamphetamine while driving on the highway near saddle road. Fearing for her safety, she reluctantly smoked the methamphetamine out of a pipe provided by Mahi,” the police report states.
Mahi is accused of sexually assaulting the girl in his vehicle and forcing her to smoke again. As the ride continued, the victim pretended to sleep. According to the police report, Mahi allegedly shackled the victim inside a yellow school bus when they arrived at his property.
On the same day she was kidnapped, the victim’s boyfriend got free, called 911, and the police issued a MAILE AMBER Alert.

The victim persuaded Mahi to take her to Cafe Pesto in Hilo Bay for lunch on Sept. 17. As soon as they reached the cafe, the victim attempted to get away from Mahi.

Good Samaritans saw Mahi and the victim fighting outside the cafe and saw the girl attempting to run away from Mahi, who allegedly told witnesses she was his “daughter,” the report states.

“That’s the girl on the news,” a witness said aloud, according to the police report.
Afterward, Mahi fled into a vehicle, which a witness photographed and reported to authorities.

Among the 52-year-old’s charges are kidnapping, first-degree terroristic threatening, and first-degree robbery, as well as meth trafficking and first-degree sexual assault. His bail is set at $2 million.

Mahi, who has a lengthy criminal history, was previously charged in 2018 with first-degree terroristic threatening.
