{"id":1948,"slug":"glensheen-duluth-minnesota","story":[{"heading":null,"paragraphs":["At seven in the morning on June 27, 1977, day nurse Mildred Garvue found Glensheen's front door unlocked. On the landing of the grand staircase lay Velma Pietila, the night nurse — sixty-seven, retired a month, back only to cover a sick colleague — beaten to death with a brass candlestick, twenty-three blows, the struggle traced down the stairs. Upstairs in her bed, eighty-three-year-old heiress Elisabeth Congdon had been suffocated with a satin pillow.","The mansion that holds Minnesota's most notorious murder was built to be beautiful, and remains so: thirty-nine rooms on twenty-two acres above Lake Superior, called the most intact house of its kind in the state. The murder file is equally well preserved — conviction, acquittal, reversal, confession, suicide — a case that took eleven years to finish convicting a man who had already confessed to everyone but the court."]},{"heading":"The documented record","paragraphs":["Chester Adgate Congdon — mining lawyer, industrialist, the man behind Duluth's North Shore drive — built Glensheen from 1905 to 1908 for his wife Clara and their seven children. He died in 1916, Clara in 1950, and the estate passed to their sixth child, Elisabeth, who never married, adopted two daughters, and spent her last two decades anonymously funding scholarships at the University of Minnesota Duluth — the institution the family had already willed the house to, back in 1969.","The murder's arithmetic was public record. Elisabeth's adopted daughter Marjorie Caldwell stood to inherit $8.2 million; her husband Roger stood to take $2.5 million of it. The Caldwells were deep in debt — house foreclosed, cars repossessed, living in a Colorado motel — and the Congdon trustees had cut them off. Roger was convicted of the murders in 1978; Marjorie was acquitted of conspiracy in 1979. In 1983 the state supreme court overturned Roger's conviction on evidence questions; facing a new trial, he confessed, took time served — five years — and refused to implicate his ex-wife. He killed himself in 1988. Marjorie later served time in Arizona for arson and fraud, and her third husband died a suspicious death."]},{"heading":"What witnesses file","paragraphs":["The haunting is the quiet kind a house like this generates: reports of figures on the staircase where Pietila fell, of a presence at the top of the stairs, of a wheelchair's occupant — local memory places Elisabeth where she lived, not where she died. Staff and students file the cold-spot catalogue; Duluth ghost tours file the rest.","The museum's own position is the file's most striking entry: the University of Minnesota, which has operated Glensheen as a museum since 1979, deliberately does not interpret the murders on its tours — out of respect for the victims' families, it says — and directs the curious to the printed case file instead. A haunted house that declines to haunt, officially."]},{"heading":"What remains","paragraphs":["Glensheen remains one of Minnesota's top historic houses, its thirty-nine rooms kept as the Congdons left them — silk wall coverings, silver, the Christmas décor Elisabeth favored — the murders included in the estate's official history but not its tour script. Visitors ask anyway; the docents answer carefully.","The record keeps a fortune, a candlestick and a confession that arrived five years late. The legend keeps two women on the stairs. The house keeps both, quietly, the way it was built to keep everything — a mansion that outlasted its family and now gives the state its most elegant, and most reluctant, ghost tour."]}],"name":"Glensheen","aliases":[],"type":"HISTORIC_MANSION","type_label":"Historic Mansion","cats":["DARK_HISTORY","LOCAL_FOLKLORE","HAUNTED_PLACE","HISTORIC_MANSION","HISTORIC_ESTATE"],"groups":["dark-history","hauntings","historic-sites","legends"],"desc":"Jacobean estate of the Congdon family, site of the 1977 double murder.","full_desc":"The 39-room Jacobean mansion on Lake Superior was built 1905–1908 for Chester and Clara Congdon.
