Second Woman Found Dead in Missouri Firefighter's Home in Three Years

The firefighter's previous fiancée died under disputed circumstances, leading to a wrongful death lawsuit; the recent death of his current fiancée is under investigation.

Dr. Sarah Sweeney, a 39-year-old podiatrist, was found dead in her fiancé, firefighter Robert Daus's home in St. Louis, Missouri, on January 13, 2024.
Three years prior, in July 2021, Daus's then-fiancée, Grace Holland, was found dead in his previous home in Creve Coeur, Missouri, from a gunshot wound to the head, ruled as suicide.
Holland's family disputed the suicide ruling, citing inconsistencies such as the gunshot wound being on the left temple despite Holland being right-handed, and her $20,000 engagement ring disappearing after being seen in crime scene photos.
Holland's family has filed a wrongful death lawsuit against Daus, alleging he controlled Holland's finances, threatened to end the relationship multiple times, and suspecting him of domestic violence.
Sweeney's cause of death is still under investigation, with autopsy results pending. Her mother mentioned Sweeney suffered from mast cell activation syndrome, a potentially life-threatening condition, but it was controlled through medication.
