He prevented her from leaving the hotel room, holding a knife and a pair of scissors to her throat, the release said. He then repeatedly raped her over the course of several hours.
When he finally allowed her to leave the hotel room, the woman got into her car and blew the horn several times to try to get help, the release said. Dunbar had stolen her phone so she could not call police.
Dunbar had previously pleaded guilty to aggravated sodomy in the case, but the Georgia Court of Appeals reversed the conviction after finding the sentence illegal, authorities said. After that, he chose to proceed with a jury trial rather than plead guilty again.
He was convicted Jan. 30 after a four-day trial. According to Georgia Department of Corrections records, Dunbar was taken to the Wheeler Correctional Facility to begin his consecutive life sentences.
