HILO, Hawaii (KHON2) -- The man who was found guilty of kidnapping and sexually assaulting a teenager in 2022 was sentenced on Friday morning. Prior to sentencing Duncan Mahi, Judge Wendy Deweese said that she had reviewed the investigation and found that "the behavior described in the pre-sente nce investigation and by the victims, evidence is that your actions were planned and predatory and not spur-of-the-moment driven by your drug use," the judge told Mahi. "And while Iʻm sure drugs played a role, you cannot blame your actions on drug use." Man in 2022 Big Island kidnapping, assault case faces minimum 20 year sentence The victims agreed to allow a plea deal for Mahi, which likely allowed him to avoid life in prison for forcing the teenage girl to restrain her boyfriend before abducting her from a beach in Waikoloa. The case spurred the use of the Maile Alert system and was only the second time it had been used in its nearly, at that time, 20-year history. 10 facts about Obama’s $18M Hawaiʻi beachfront mansion Mahi was found guilty on three counts. Count one, kidnapping, a class A felony; count two, kidnapping, a class B felony; and count eight, sex assault. Judge Deweese sentenced Mahi to 20 years with a mandatory minimum sentence of 13 years and four months for count one; 10 years with a mandatory minimum six years and eight months for count two; and 20 years with a mandatory minimum of 13 years and four months for count eight. Hawaii residents urged to make sure they receive Amber Alerts on their phones Counts one and two will run consecutively and the sentence in count eight will run concurrently with count one, totaling 30 years with a mandatory minimum of 20 years. Mahi was also charged $1,010 to be added to the crime victims fund. Mahi declined to address the court. "Once I sentence you in this case this will be over for you. But the victims and their families will continue to suffer the consequences of your selfish and cruel actions." The victimʻs family expressed relief after the hearing but mostly praised the victim for her smart and quick thinking which allowed for her escape when she told Mahi that she was hungry and asked him to take her to Cafe Pesto, where she was freed. "I really want to commend her for really saving herself in this situation. She was so smart, so brilliant. She manipulated and outsmarted her abductor and she is her own hero," the victimʻs mom said. "We would also like to thank Cori Takaki and Bridge Hartman who assisted in her rescue at Cafe Pesto. Wonderful people. Thank you so much." She also thanked Hawaii police and fire departments, the prosecutors, family, friends and Judge Deweese.
