(CBS/AP) MILWAUKEE - A Wisconsin judge ordered 73-year-old Robert Hill to stand trial Monday in order to determine whether he's sexually violent after being suspected of murdering a young girl in 1970.
Hill finished serving a 10-year sentence for allegedly sexually assaulting four children under the age of 10 between 1995 and 2002. Police said he confessed to the murder of 9-year-old Donna Willing in February 1970 but later recanted. They say he knew details that hadn't been released.
Biological evidence was destroyed or lost in the 1990s that could help convict Hill, so prosecutors are trying to use the state's sex offender law to keep him in custody. A judge determined Monday there's enough evidence to move to trial. Prosecutors will have to prove he's a sexually violent person.
