The Ramsey County Sheriff’s Office is asking the public’s help in locating the remains of a Vadnais Heights woman that investigators believe are buried in an abandoned farm building in eastern North or South Dakota. They’re urging residents to check barns, outbuildings and other areas on their property. Authorities allege 51-year-old Timothy Barr of Lakeville killed 45-year-old Michelle Newell and buried her under hay or grass clippings in late August. Barr is charged with second-degree murder and criminal vehicular homicide.
