Time in a state mental institution has been ordered for an 18-year-old Janesville man accused of attempted first-degree intentional homicide. Gavin D. Roetteger is accused of stabbing his grandfather three times at their home on May 18th. Roetteger’s defense attorney says the county filed a civil action resulting in the commitment to the Winnebago Mental Health Institute. The Rock County Jail Commander says the civil commitment is part f normal care for people suffering from “various difficulties”. A judge could rule on Roetteger’s competence to stand trial June 14th.
