The Kenai Superior Court sentenced Kevin Tuckfield, 35, to serve 100 years for sexual assault in the first degree and assault in the third degree last Wednesday, according to a news release from the state Department of Law.

The charges were related to a 2014 incident in which Tuckfield sexually assaulted a female civilian employee while working in the Spring Creek Correctional Center library in Seward, the release said.

At the time of the assault, Tuckfield was incarcerated for a prior sexual assault conviction.

The release also says Tuckfield has two additional cases pending trial in Anchorage. In one case, he is charged with both first-degree and second-degree murder. In the second case, he is charged with escape, attempted kidnapping and first-degree robbery.

According to the release, Tuckfield faced the maximum sentence for a single offense — 99 years — since the incident was his third felony sexual assault conviction. He was given one additional year of consecutive jail time for the assault in the third degree conviction.
