LANCASTER (WKOW) -- A Wisconsin inmate serving a life sentence will spend another 20 years in prison after he pleaded no contest to killing a prostitute nearly 30 years ago.
Prosecutors charged Gregory Otterbeck, now 54, with second-degree murder in the death of 23-year-old Rockford, Ill., prostitute Thomasina Dunivant. Authorities found her dead on the side of a Grant County road in December 1980.
State investigators matched DNA found on her body to Otterbeck in September 2007 and have been working to build their case ever since. In a matter of hours Friday, prosecutors charged him, he pleaded no contest and Judge Robert P. VanDeHey gave him 20 years.
Otterbeck's attorney, Rose Oliveto, says he wanted to do the right thing.
Otterbeck already is serving life in the death of another woman, Jodi Bausman of Dubuque, Iowa, in 1981. VanDeHey ordered Otterbeck to serve the 20 years simultaneously.
