Defense attorneys say that the brother of the man accused in the 1980 rape and murder of a UW-Madison student confessed to the crime and that state prosecutors have withheld that information for the past 13 years.
In a motion filed April 17 with the 4th District Court of Appeals, attorneys for Ralph Armstrong also say that a state prosecutor knowingly destroyed DNA evidence that might have proved that it was Armstrong’s brother, Steve, who killed Charise Kamps.
