Sandra Horwath was 33 and a mother of three when she disappeared from her Braeburn Circle apartment in Ann Arbor, Michigan. On the evening of October 1, 1973, she returned from a shopping trip with her children, took a phone call about 9:30 p.m., and tucked her daughters into bed at 10:00 p.m. The next morning the children woke to an empty home; Sandra never reported to her job at the University of Michigan hospital.

The scene showed signs of disturbance: flowerbeds outside the residence had been trampled. Sandra’s car and watch were left behind, while her purse and checkbook were missing and have never been recovered. Her ex-husband lived in Rochester, Michigan, had an alibi for the night and was cooperative with police; he later took the children to live with him.

In 1976 investigators learned that Gary Addison Taylor, arrested in Houston, had confessed to killing and burying multiple people near a property he had rented in Onsted, Michigan. Sandra was known to be an acquaintance of Taylor and may have dated him, making him a person of interest, but her remains were not found on his property and he denies involvement. The case remains open and unsolved.

If anyone knew Sandra, her movements that night, or has information about contacts she had in 1973, please share what is known.
