Prosecutors say Falkenberg killed LaFramboise in Yankton, where they both lived, then drove to Menominee County, Michigan, where he grew up. Authorities say he discarded LaFramboise’s dismembered body in the Little River, where two boys found it March 16.
A probable cause affidavit says Falkenberg told his sister he argued with LaFramboise, pushed her and she hit her head and died. Defense attorney Clint Sargent says Falkenberg plans to plead not guilty.
