Locals were shocked when prominent St. Paul, Minnesota butcher and prominent local citizen Louis Arbogast was murdered. Arbogast, his wife, and four daughters lived a mundane, uneventful life in a large home near the city’s downtown. From the outside, they appeared to be a happy family that loved each other.
In the early morning of May 13, 1909, everything changed, and the once-unified family was torn apart. In the end, the death of the family patriarch left both the authorities and the community with infinitely more questions than answers.
Smoke emanated from the second floor of the house. Ida Arbogast found her unconscious father lying in bed in her parents' bedroom. Flames engulfed his mattress. Despite the help of a sixteen-year-old newspaper boy and neighbors, Mr. Arbogast, who had suffered a series of blows to the back of his head, died on the way to the hospital.
Police discovered a blood-stained ax in the house's basement during their investigation. Because the windows and doors were locked, the initial assumption was that the murderer had open access to the home. The police questioned everyone who was in the house. Authorities found it impossible to get information about the crime from the family. The family's unwillingness to cooperate baffled them.
Arbogast's murder was gruesome. He was repeatedly struck in the back of his head with a four-pound ax. His kerosene-soaked bed was set on fire while he lay on it covered in blood and feathers. Sadly, death didn't occur until well after firefighters removed him from the flames.
Based on evidence discovered in the house, the police soon zeroed in on wife, Minnie, and daughter Louise. Both were charged with first-degree murder, and if either was convicted, would likely face death by hanging.
Since the murder was so brutal, the authorities believed a “crazy person” committed the crime. They investigated Louise. They weren't the only ones looking into the matter. Her mental health became a focus of everyone involved in the case. Although her father clearly regarded her as his favorite child, she had not been considered mentally sound for several years.
Besides her long-time fascination with fortune-tellers and clairvoyants, Louise believed a mysterious man was pursuing her and her sister Ida, intending to hurt them. Because of her condition, she spent the previous winter away and only recently returned home.
As soon as authorities put mother and daughter in the same room, Mrs. Arbogast, who had initially asserted Louise's innocence, went on the offensive. Louise told her daughter that since she didn't kill her husband, Louise must have murdered her father. Mrs. Arbogast, who claimed to have been in the bathroom when the crime happened, confessed that Louise was in the bedroom when she exited the bathroom.
“Louise, it is either you or me! Tell the truth — tell the truth. You were outside father’s door when I came from the bathroom. You must tell the truth!" ~ Mrs. Arbogast to daughter Louise (reported in the May 19, 1909 New Ulm review.)
Four days before her father was killed, Louise had returned home from an extended stay at an Eau Claire sanitarium. Her mother told authorities that Louise had attacked her with a hammer the night before the murder occurred, and doctors had warned Mr. and Mrs. Arbogast not to bring their daughter home too early. Upon further investigation, police concluded Louise had developed some kind of 'demonic frenzy' because of her interests.
As a result, she went temporarily insane and killed her father.
Mrs. Arbogast wasn't exactly in the clear. The ever-changing stories she told weren't incriminating, but they didn't exonerate her either. Initially, she testified she was in the bathroom for five minutes while the crime was being committed, but people were skeptical. She later said she was in the bathtub. According to a neighbor, Mrs. Arbogast had told her she was making breakfast when the murder took place, not in the bathroom, as she had previously reported. Ida said she had pulled her mother from the flaming bed, but she did not mention the bathroom.
There was also a question about the intensity of the relationship between Mr. Arbogast and his daughter. The papers reported he had recently told his wife he was leaving the family to go to Alaska with Louise and her fiance. There was soon talk of a father and daughter having a secret sexual relationship. If Mrs. Arbogast had learned about it, she may have attacked her husband and killed him in anger. The police had to consider it as a motive.
Both ladies pleaded not guilty, and the trial was set for the fall of 1909. The first case to go to trial was Mrs. Arbogast's. After two weeks of evidence and witness testimony by the prosecution and defense, a jury of twelve men ruled she was not guilty of first-degree murder. A lighter sentence was proposed to the judge by the jury - possibly justifiable homicide; however, he refused, saying that the first-degree murder finding was all-or-nothing.
A little over a week after the case against Mrs. Arbogast resulted in acquittal, the prosecution dropped the case against her daughter. The Ramsey County Attorney felt the evidence against the girl, similar to that used against her mother, wasn't enough to secure a conviction.
The case was eventually relegated to history books, unsolved.
People were shocked when none of those responsible for Louis Arbogast's gruesome death would be held accountable. Clearly, someone who lived in the house caused his death. The local authorities agreed. In newspaper interviews following the end of the trial, the police stated they believed they had found the killer or killers but did not achieve the conviction they had hoped for.
Eventually, life in the Arbogast household returned to normal - or at least as normal as possible considering the circumstances. Even though the killing of the family patriarch likely haunted each of the surviving members, they refused to discuss it.
