Thursday a judge sentenced a 58-year-old to 15 years in prison for sexually assaulting an "incapacitated" woman in 2014.

In a release sent by Anchorage District Attorney Clint Campion, the incident happened June 6, 2014 while two soldiers were shopping for cars at an Anchorage dealership. From the car lot, they saw Timothy Walunga sexually assaulting a woman. The soldiers called police and followed Walunga as he walked away from the scene.

The State Crime Detection Laboratory confirmed they found the woman's DNA on Walunga's hands, according to the release.

The District Attorney's Office says Walunga faced a sentence of 15 to 25 years because of a prior sexual assault conviction. The judge decided to suspended prison time by five years and place the 58-year-old on five years probation.

"Judge Corey stated that he considered the sentencing factors of community condemnation and the reaffirmation of societal norms to be 'at the top of the list' in this case," the release said. "He also found that Walunga’s prospects for rehabilitation were unlikely given his criminal history."

When Walunga is released, he is required to register as a sex offender for the rest of his life.
