Lizzie Lochner returned home from a night on the town sometime after midnight the morning of June 2, 1894. Her husband Joseph, who stayed home with the children—4-year-old Rosa and her infant brother— berated Lizzie for her for coming in so late. They began to loudly argue the matter as they had done many times before.
Their lodger, Gus Englund, was used to being awakened by the Lochner’s arguing but this night was different. The voices grew to a crescendo followed by a few minutes of silence, then the sound of a gunshot. Joseph Lochner burst into his room and said, “Oh, Gus, Gus, I have done it. I have killed my wife.” He then ran out of the building by the back door.
