The day nurse arrived at Glensheen at seven on Monday morning, June 27th, 1977. She had worked for Elizabeth Congden for years. She knew the routine, the house, the layout, what to expect when she walked through those doors. Everything felt wrong immediately.

The mansion was silent, too silent. Normally Velma Pietila, the night nurse, would be moving around, preparing breakfast, getting Elizabeth ready for the day. The transition between shifts was always smooth, professional; they had done it hundreds of times. But Velma was not in the kitchen.

She was not in Elizabeth’s room. The house felt empty in a way that made the nurse’s skin crawl. She walked through the first floor, past the reception rooms, past the library with its thousands of books, past the breakfast room with its distinctive green tile walls. Everything looked normal, furniture in place, no obvious signs of disturbance.

Then she reached the grand staircase. Velma Pietila lay at the bottom, blood pooled around her head. A brass candlestick, bent from impact, lay a few feet away. The nurse ran upstairs.

Elizabeth’s bedroom door stood open. Dresser drawers had been pulled out, contents dumped. A jewelry box was missing from the dresser top. The room had been searched, ransacked.

Elizabeth Congden lay in her bed, the covers pulled up neatly, almost peaceful, but something was wrong with her face, the color, the stillness. The nurse checked for a pulse. Nothing. Elizabeth was dead.

A satin pillow lay next to her head. She ran back downstairs and called the police. Officers arrived within ten minutes. They recognized the address immediately; everyone in Duluth knew Glensheen, the Congden mansion, one of the city’s most prominent landmarks, a museum-quality estate still occupied by the family that built it.

They found Velma Pietila first. She had been beaten repeatedly. The candlestick had been used as a weapon. This was not a single blow that accidentally killed someone; this was rage or determination or both.

Upstairs, Elizabeth Congden lay in her bed, eighty-three years old, partially paralyzed from a massive stroke thirteen years earlier. She could not walk, could barely speak. Someone had suffocated her with a pillow, held it over her face until she stopped breathing. It would have taken several minutes.

The killer had to stand there, pressing down, waiting for an elderly, disabled woman to die. The initial assessment was straightforward: burglary. An intruder had broken in during the night. Velma heard something, came to investigate.

The burglar panicked, killed her, then went upstairs and killed Elizabeth to eliminate witnesses. It was a reasonable theory. Wealthy homes got targeted. Glensheen sat on valuable lakefront property in a relatively isolated area.

But the theory had problems. Nothing else was taken. The house was filled with valuable antiques, art, silver, collections worth hundreds of thousands of dollars. A burglar who went to the trouble of breaking into Glensheen would have taken more than one jewelry box.

The violence was extreme. And the entry point bothered investigators: a window in the billiard room showed signs of forced entry, but the glass had fallen outside, not inside. Someone familiar with the house might know that detail mattered. Staged crime scenes often got small things wrong.

By mid-morning, detectives were asking different questions. Who benefits from Elizabeth Congden’s death? Who knew the house layout? Who knew Elizabeth was helpless and Velma was the only person protecting her?

The answers led to family. Elizabeth Congden had two adopted daughters: Jennifer, who lived a quiet life and maintained good relationships with everyone, and Marjorie. Marjorie Congden LeRoy Caldwell, a woman with a reputation, a history, and serious financial problems. Within hours, investigators learned Marjorie stood to inherit over eight million dollars when her mother died.

They learned she was broke, her house foreclosed, cars repossessed, living in a hotel in Colorado because she could not afford rent anywhere else. They learned her new husband Roger Caldwell was unemployed, that the couple had been cut off by the Congden family trustees, that Marjorie had been begging for money for months. And they learned something else that made the hair on the backs of their necks stand up. Three months earlier, in March 1977, the Colorado Bureau of Investigation had contacted the Congden family trustees.

They had received information that Marjorie Congden Caldwell was looking for someone to kill her mother. The trustees had increased security at Glensheen, but Elizabeth had refused to believe her daughter would hurt her. She had dismissed the warnings, insisted Marjorie loved her. Now Elizabeth was dead, suffocated in her bed, and detectives had to figure out if a daughter had murdered her mother for money.

To understand how it came to this, the story has to go back, back to when Chester Congden was just a struggling lawyer. Chester Adgate Congden was born on June 12th, 1853, in Rochester, New York. His father was a Methodist minister. His mother came from a respectable but not wealthy family.

Chester grew up with modest means, religious values, and an understanding that success would require hard work. Nothing about his childhood suggested he would become one of the wealthiest men in Minnesota. He attended Syracuse University in 1871. There he met Clara Hesperia Bannister, daughter of another Methodist minister from San Francisco.

They both graduated in 1875. Chester studied law; Clara took a teaching position at a women’s college in Ontario. They wrote letters, made plans, but Chester needed to establish himself financially before he could marry. The years after graduation were difficult.

He was admitted to the New York bar in 1877, but work was scarce. He wrote Clara letters filled with self-doubt, called himself a second-rate lawyer, joked bitterly that he should have become a cowboy instead. In 1878, desperate for income, he took a job as a school principal in Chippewa Falls, Wisconsin. The pay was terrible.

He lasted less than a year. In 1879, Chester moved to St. Paul, Minnesota, opened a law practice, and was admitted to the Minnesota bar. The practice did modestly well, enough to survive, not enough to thrive.

Then he met William Billson, the United States District Attorney for the state of Minnesota. The two men hit it off immediately. When a position opened, Chester became Billson’s assistant. Chester borrowed several hundred dollars from a friend and proposed to Clara.

On September 29th, 1881, ten years after they first met at Syracuse, they married in a small ceremony. Their first child, Walter Bannister Congden, was born in 1883, then Edward in 1885, Marjorie in 1887. The family was growing, expenses mounting. In 1892, William Billson made Chester an offer.

Billson had left the district attorney position and established a private practice in Duluth. The city was booming. The Mesabi Iron Range, sixty miles north, had just been discovered. Duluth was becoming a shipping hub.

Billson wanted a partner, someone he trusted. Chester accepted, and the Congden family moved to Duluth in May 1892. The move brought tragedy: their son John Robert, nearly two years old, died in May 1893 from scarlet fever. A daughter, Elizabeth Manoring, was born in April 1894, then Robert in 1898.

In 1896, the Congdens purchased their own home, a three-story Victorian masterpiece called the Redstone, faced in red Lake Superior sandstone, designed by renowned Duluth architect Oliver Traphagen. It was the kind of house that announced a family on the rise. But what really changed everything was iron ore. The Mesabi Iron Range had been discovered in 1890 by Leonidas and Alfred Merritt.

They had found hematite ore lying close to the surface, rich deposits, easy to extract, the largest iron ore body on the planet. But the Merritts struggled to find investors. Andrew Carnegie, who ran the largest steel company in America, dismissed the ore as a sample of dirt, inferior quality, not worth investment. Henry Oliver disagreed.

He ran Oliver Steel in Pittsburgh, the second-largest steel manufacturer in the country. Oliver traveled to Minnesota in 1892, visited Duluth, and toured the Mesabi Range personally. He liked what he saw. He needed local legal representation, so he went to William Billson’s office in Duluth.

Billson was away. On a tight schedule, Oliver reluctantly agreed to meet with Billson’s junior partner instead: Chester Congden. The two men connected immediately. Oliver proposed a partnership.

He would create the Oliver Mining Company. Chester would serve as the company’s agent in Minnesota, leasing and purchasing mining property. In exchange, Chester would receive fees, commissions, and stock. Chester accepted.

For several years, Chester worked tirelessly. His income increased dramatically. But the Mesabi Range attracted the attention of even larger players. John D.

Rockefeller wanted control of the range. Andrew Carnegie, despite his earlier dismissal, changed his mind and aggressively pursued Mesabi properties. Henry Oliver was caught between two titans. In 1901, J.

P. Morgan stepped in, brokered a deal, bought out Rockefeller, Carnegie, and Oliver Mining’s holdings, and combined them into a new entity: United States Steel Corporation, the first billion-dollar company in history. Chester Congden, as a stockholder in Oliver Mining, saw his shares skyrocket. In six years, his stock rose 555 percent.

Almost overnight, he went from successful lawyer to one of the wealthiest men in Minnesota. Chester did not stop there. He purchased cheap mining land on the western Mesabi Range, land others thought worthless because the ore needed processing before it could be used in steel mills. He partnered with Guilford Hartley and convinced U.

S. Steel to invest ten million dollars in a concentration plant. When the plant was built, Chester and Hartley’s land became extremely valuable; they leased it back to U. S.

Steel at enormous profit. Chester diversified: copper mines in Arizona, an irrigation canal in Washington’s Yakima Valley, board seats at banks and mining companies. By 1904, he was arguably the richest man in Minnesota. Only railroad magnate James J.

Hill may have had more money. Chester wanted something more: an estate, a mansion, a palace on Lake Superior that would announce that Chester Adgate Congden had arrived. In 1905, he began planning Glensheen. He and Clara traveled, studied architecture, visited grand homes on the East Coast.

They purchased twelve acres on the shore of Lake Superior, between Tischer Creek and Bent Brook, heavily wooded, running from London Road down to the lake. Clara wrote in her diary, “I will have quiet neighbors,” referring to the cemetery west of the property. Chester hired Clarence H. Johnston as architect, Minnesota’s most prominent designer.

Johnston proposed Jacobethan Revival style, inspired by seventeenth-century English country estates: asymmetrical design, brick construction with granite trim, prominent gables. For the landscape, Chester hired Charles Welford Leavitt Jr. from New York. The William A.

French Company handled interior design. Construction began in 1905 and would take three years and nine months. Underground tunnels were dug from London Road to bring in water, gas, and power lines, so utilities would not mar the landscaping. Water for the gardens came from Tischer Creek, diverted into a 60,000-gallon reservoir between Superior Street and London Road, still in use today.

Leavitt designed the landscape to retain much of the original vegetation, with trails and rustic bridges through the natural growth. The estate included a large vegetable garden, greenhouse, orchard, and cow barn, tennis courts, a bowling green, a large pier on Lake Superior, a boat house, and four gardener’s cottages. The main house rose steadily: thirty-nine rooms across multiple floors, 20,000 square feet of living space. Johnston used different woods throughout: Circassian walnut, mahogany, cypress, fumed oak, enameled birch, American walnut.

Each room’s furniture matched the wood used in that room’s trim and paneling. The hallways featured original stenciling in Arts and Crafts style, hand-carved wood details, wall and ceiling coverings made from wool, silk, filled burlap, and gold leaf. Even the doors showed craftsmanship, each using two kinds of wood: oak on the hallway side, the room’s signature wood on the interior side. The house had central heating and humidification, a central vacuum system, and both gas and electric lights as backup for the unreliable electricity of 1905.

The lower level held utilitarian spaces: milk room, laundry, butler’s quarters, but also leisure areas, a billiard room, a recreation room, and what the family called the “little museum. ” Throughout the house, symbols appeared repeatedly: lions representing power, pineapples representing hospitality. The breakfast room became one of the house’s highlights. Designed by John Bradstreet of Minneapolis, it featured green tile on walls and floors, three walls of stained-glass windows overlooking the terrace gardens and Lake Superior.

The grand staircase rose through the center of the house with carved railings and art-glass windows. The final bill came to $854,000, equivalent to over twenty-two million dollars today. Chester paid without complaint. On November 24th, 1908, the Congden family moved into Glensheen.

The name came from two sources: Chester’s ancestral village of Sheen in Surrey, England, and “glen,” the Scottish word for narrow valley, referring to the ravines of Tischer Creek and Bent Brook that framed the property. Chester was fifty-five when Glensheen was completed. He had eight more years to enjoy it. In November 1916, he died of a pulmonary embolism in St.

Paul. He was sixty-three. Clara remained at Glensheen for another thirty-four years, maintaining the house and gardens exactly as Chester had envisioned. In 1950, Clara died at age ninety-six.

She had lived at Glensheen for forty-two years. After Clara’s death, Elizabeth was the logical heir. She had never left. She inherited the estate.

She was in her fifties, unmarried, living alone in thirty-nine rooms. The solution came through adoption. In 1932, Elizabeth adopted her first daughter, an infant originally named Jacqueline Barnes, renamed Marjorie Manoring Congden. Three years later, in 1935, she adopted a second daughter, Jennifer Susan Congden.

The girls grew up at Glensheen with every advantage, but there were differences. They were adopted, not blood Congdens. Some family members never quite accepted them, made subtle distinctions between real family and adopted children. Marjorie seemed to feel this more acutely.

She was temperamental, difficult, required more attention. Jennifer was quieter, easier. Then, in 1964, Elizabeth suffered a massive stroke at age seventy. It left her partially paralyzed, unable to walk, barely able to speak.

She required round-the-clock nursing care. Nurses were hired, day shifts and night shifts. In 1968, Elizabeth donated Glensheen to the University of Minnesota Duluth. The university would own the property after her death, but Elizabeth retained a life estate.

She could live there as long as she survived. The university would convert the estate to a museum. By 1977, Elizabeth was eighty-three, completely dependent on her caregivers. She had no idea her daughter Marjorie was desperately broke in Colorado.

Marjorie had married Richard LeRoy in 1951 at age nineteen. The marriage produced seven children and lasted nineteen years, ending in divorce in 1970. The family had lived in Marine on St. Croix, Minnesota, in constant financial crisis.

In the late 1960s, their house burned under suspicious circumstances; the insurance investigation raised questions, but nothing was proven. After the divorce, Marjorie moved to Colorado in 1975, leaving most of her children behind. She met Roger Caldwell, recently divorced, struggling financially. They married quickly in 1976.

They hatched plans for a horse ranch, purchased property and horses with borrowed money, and within months lost everything to foreclosure and repossession. They moved into the Holland House Hotel in Golden, Colorado, because they could not qualify for an apartment lease. Marjorie received approximately $22,000 per year from one of the Congden trusts. It was never enough.

By spring 1977, they were desperate. In March 1977, the Colorado Bureau of Investigation contacted the Congden family trustees. They had received information that Marjorie was looking for someone to kill her mother. The trustees increased security at Glensheen.

Elizabeth refused to believe her daughter would hurt her. Three days before Elizabeth’s death, Marjorie signed a document: a power of attorney authorizing Roger to receive approximately $2. 5 million of her expected inheritance directly, not subject to the trustees’ control. On the weekend of June 24th through 26th, Roger disappeared from the hotel.

He left a note for Marjorie’s sixteen-year-old son Rick, saying he and Marjorie would be with real estate agents all weekend, and left fifty dollars. The real estate agent never saw Roger that weekend. He vanished, with no airline records, no credit card receipts, no witnesses. Then early Monday morning, June 27th, Elizabeth Congden and Velma Pietila were found murdered.

Roger reappeared at the hotel Monday afternoon with bruises on his face and cuts on his hands. He claimed a horse had kicked him. At the funeral three days later, relatives noticed Roger’s injuries and his nervousness. Family members approached investigators, told them about Marjorie’s financial problems, the hitman rumor from March, the pattern of fires and suspicious incidents, the inheritance worth millions.

A week after the murders, a coin dealer in Colorado contacted investigators. Someone had mailed him a Byzantine gold coin asking for an appraisal. The return address was Roger Caldwell’s. The coin matched items from Elizabeth’s jewelry collection.

Detectives obtained a search warrant for the Caldwells’ hotel room. They found more jewelry matching items taken from Glensheen and a wicker basket similar to the missing jewelry box. Then came the fingerprint on the envelope containing the gold coin: a thumbprint belonging definitively to Roger Caldwell. He had mailed himself stolen property from a murder scene and put his thumbprint on the envelope.

On July 6th, 1977, police arrested Roger Caldwell on two counts of first-degree murder. He maintained his innocence, claimed he was being framed. On July 7th, authorities arrested Marjorie, charging her with conspiracy to commit murder, aiding and abetting, being an accomplice to two killings. She was released on $100,000 bond.

Roger’s trial was moved to Brainerd, Minnesota, Crow Wing County, due to pre-trial publicity. It began in July 1978, exactly one year after the murders. The prosecution presented the stolen jewelry, the wicker basket, the Byzantine gold coin, the fingerprint, the injuries, his missing whereabouts, and the motive of an eight-million-dollar inheritance. The defense attacked each element but could not produce proof of how Roger traveled.

The jury deliberated for three days and returned a verdict: guilty on both counts. First-degree murder. Two consecutive life sentences. Marjorie’s trial began in April 1979 in Hastings, Minnesota, Dakota County.

She had not been at Glensheen that night. Proving conspiracy required showing intent and planning. The prosecution built the case around motive and timing: the financial desperation, the inheritance, the power of attorney signed three days before the murders, the hitman rumor, and testimony from Rebecca LeRoy, Marjorie’s own daughter, who claimed her mother had once tried to strangle her. The marmalade incident also came up: years earlier, Elizabeth had become violently ill after eating marmalade Marjorie brought her; blood tests showed drugs, and the jar disappeared.

Marjorie’s attorney, Ron Meshbesher, made her sympathetic. She dressed conservatively, wore minimal jewelry, and sat at the defense table knitting quietly, looking harmless and grandmotherly. Meshbesher attacked every piece of the prosecution’s case: the power of attorney was normal financial planning, the hitman rumor was unverified gossip, Rebecca LeRoy was a troubled daughter with grudges, the marmalade incident was never investigated, the house fire was never proven as arson. He argued that Roger committed the murders on his own, hoping to secure the inheritance, without telling Marjorie.

Marjorie testified in her own defense. She spoke about loving her mother, about the adoption, about feeling rejected by some family members. She cried discussing Elizabeth’s death, said Roger must have acted alone. Prosecutors tried to break her on cross-examination, but she held firm.

The jury deliberated for nine hours and returned a verdict: not guilty. All charges. Marjorie walked free. After the trial, some jurors threw a party and invited her.

She attended. Four of Marjorie’s own children filed a civil suit contesting her right to inherit, arguing she should not profit from Elizabeth’s death. Eventually a compromise was reached: Marjorie would receive income from the trusts, limited to $40,000 per year. The millions she had supposedly killed for never materialized.

Roger Caldwell sat in Stillwater Prison serving two consecutive life sentences. His lawyers found something: during Marjorie’s trial, a witness named Candace Buyers had testified about other Congden family members possibly being involved, suggesting alternative suspects and a possible frame-up. The Minnesota Supreme Court reviewed the appeal in 1982 and made a stunning decision: the conviction was overturned. Roger deserved a new trial.

The prosecution, facing faded memories and the complication of Marjorie’s acquittal, made a calculated decision: offer a plea deal. On July 5th, 1983, Roger Caldwell appeared in court. He accepted a plea bargain: guilty to two counts of second-degree murder in exchange for time served, five years, and immediate release. Part of the deal required confession.

Roger admitted he had traveled to Minnesota, entered Glensheen through the billiard room window, encountered Velma Pietila on the staircase, beat her to death with the candlestick, went upstairs, suffocated Elizabeth with a pillow, took the jewelry box, drove Velma’s car to the airport, and flew back to Colorado. He claimed he had used cash and possibly fake identification. His confession did not implicate Marjorie. Roger Caldwell walked out of Stillwater Prison in July 1983, age fifty.

He struggled with depression and alcoholism. On May 18th, 1988, he committed suicide at age fifty-five, by poison, leaving no note. Marjorie continued living. She remarried, to Wallace Hagen, though it later emerged she had never properly divorced Roger, making the marriage bigamy.

In 1982, the house she shared with Wallace burned down, another suspicious fire with an insurance claim. Marjorie was charged with arson, convicted, and served twenty-one months. More incidents followed: forgery, theft, fraud. Her children remained estranged.

Glensheen opened as a museum in July 1979, two years after the murders. Initially, tour guides were instructed not to mention the murders; the university wanted the estate appreciated for its architecture and history, not sensationalized as a crime scene. But visitors knew, and the policy eventually changed. Guides acknowledged the murders and answered questions.

The mansion attracted over 100,000 visitors annually. Ninety-five percent of what visitors saw dated to 1908. The estate appeared on the National Register of Historic Places. School groups visited, weddings were held on the grounds, and the gardens still functioned as Leavitt designed them.

Marjorie moved to Arizona. In 2007, she was arrested again on fraud charges, writing checks on a friend’s account. By 2010, she was largely confined to Arizona, her children estranged. She gave occasional interviews, always maintaining her innocence, always claiming Roger acted alone.

She had been acquitted; double jeopardy protected her. She could claim innocence forever without fear of being tried again. Jennifer Johnson, Marjorie’s adopted sister, lived until 2017, dying at eighty-two. She had maintained throughout her life that Marjorie was guilty.

The family division never healed. The murders will always be part of Glensheen’s story, impossible to separate. Two women killed in a house built for beauty and family harmony. Yet visitors leave Glensheen impressed by beauty more than darkness.

The architecture dominates. The murders became a footnote: important, memorable, but not defining. The house is bigger than the crime. The crime Marjorie committed to get money ended up benefiting the house she tried to inherit, not her.

Chester’s mansion survived, thriving, open to everyone, a public treasure rather than a private residence. The house Chester built survived everything, including murder, and it will stand long after everyone involved is forgotten.
