GREEN BAY - A former University of Wisconsin-Oshkosh student has been sentenced to three years and four months in prison for possessing the deadly poison ricin.
Twenty-one-year-old Kyle Allen Smith of Oshkosh pleaded guilty in March. He admitted growing castor beans and extracting ricin from them. A count of developing a toxin for use as a weapon was dropped in a plea agreement.
Smith was arrested and charged in November after two professors became concerned over what they said were his questions about producing ricin.
