Jeffrey Drye, 25, has been sentenced to 21 months in federal prison, a year’s supervised release, and a lifetime requirement to register as a sex offender with the state of Hawai‘I following his conviction for sexual assault of a minor in the park in January, 2010. Drye, two other men, and a female minor hiked into the park’s Kahuku unit at night. After making a campfire, the two other men walked back to their car, which was about a mile away, to get some food, leaving Drye alone with the girl. The assault occurred during their absence. Drye was indicted last year for abusive sexual contact and sexual assault in the first degree. A jury found him guilty of the former charge and not guilty of the latter during a four-day trial last June. The investigation was led by the Investigative Services Branch and park rangers from Hawai‘i Volcanoes National Park, with assistance from the Hawai‘i County Police Department, and the Federal Bureau of Investigation. The case was prosecuted by the United States Attorney’s Office for the District of Hawai‘i.
