A Yankton man has been indicted on murder charges by a federal grand jury.
Stephen Falkenberg, 45, is charged in connection with the March 1 death of 46-year-old Tamara LaFramboise, also of Yankton, whose body was found in Menominee County in Michigan on March 16, Attorney General Jason Ravnsborg announced Monday afternoon.
Falkenburg is facing one count of second-degree murder and one count of first-degree manslaughter. If convicted on the murder charge, a Class B felony, he would be required to spend life in prison; if convicted of manslaughter, a Class C felony, life in prison would be the maximum possible sentence he could receive.
The South Dakota Division of Criminal Investigation, the Yankton County Sheriff's Office, the Yankton Police Department, the FBI and Michigan authorities are investigating the case.
