On February 16, 1982, Garnetta Haggard, 22, was one of seven people killed at her parents’ farmhouse in Farwell, Michigan, in what investigators later called the Rock Road massacre. The victims included Garnetta; her parents, George Post, 54, and Vaudrey Post, 43; her half-sister Helen Gaffney, 29; and three of Helen’s children, Angela, 10, Thomas, 7, and Amy, 4. A one-year-old child survived, found alive and shielded by her mother’s body.

Authorities say the killings were carried out by Garnetta’s estranged husband, Robert Lee Haggart, 31, who reportedly went to the Post family farm armed with a shotgun and a handgun amid contentious divorce proceedings and a scheduled court hearing the next day. Haggart fled Michigan but was captured on February 18, 1982, in Jasper, Tennessee, and returned to face charges.

The case left a rural community reeling. If anyone knew Garnetta, the Post family, or saw anything relevant around February 16–18, 1982, please come forward with information.
