An Oklahoma man who pleaded guilty to a sexual assault in Wisconsin from 1990.
The man could face up to 20 years in prison.
Glendon C. Gouker is in custody here in Oklahoma right now.
The 41-year-old pleaded guilty in Waupaca County earlier this month to sexually assaulting a 20-year-old woman in 1992.
He's awaiting trial on murder charges from 2010.
Wisconsin court records say he waived his right to appear in person for sentencing, but he will appear by video-conference.
Prosecutors say they'll look for the maximum 20-year sentence.
Gouker has also been named a "person of interest" in the stabbing deaths of two people in Weyauwega last month.
